This kit can be installed on any Gaggia Classic with a boiler like this, however the power tapping may vary based on machine age. The kit should work with any machine that has a solenoid valve and an M4 thread in the boiler for the temperature probe, such as the Rancilio Silvia. Want to support the channel? Shop Amazon with my affiliate link: amzn.to/3tU9btX (it doesn't cost you anything more, but I earn a small provision if you buy anything). Here's a pick of how to place the reed switch: th-cam.com/users/postUgkxokXcHxXrk3V10UkKw8E6yxQhLUvz7kZ9 From the maker: "When customers ask us about compatibility, our easiest answer for them is what their boiler looks like, is it like in your video?. If so the PID kit will fit their machine. Regarding other machines (such as the Silvia): if the boiler has a M4 thread for the temperature sensor and a solenoid valve for the timer the kit will be compatible."
I plan to purchase the Gaggia Classic Pro in the future. I appreciate that you make these videos as I will watch it again once I am able to buy my dream machine.
I just completed this upgrade following your instructions as well as the ones included. It was just as easy as it looks here and anyone can do it. I also like the included tank light, very useful.
I just received my new Gaggia Classic Evo Pro, and now I’m thinking of tearing it apart! Haven’t even pulled one shot of espresso yet LOL! But this looks fun!
Thank you so much for making this video. It made me realise that modifying the Gaggia with PID temperature control is absolutely not for me! If I attempted this I just know something would go wrong. You have the patience of a saint and a useful tool kit, I have neither! I want a machine with PID control so I’ll buy something else.
@@TomsCoffeeCorner Thank you, very helpful suggestions. My current favourite (at about £1,300, my budget is creeping up!) is the Fracino Piccino PID. I haven't looked at either of your suggestions yet so I'll get onto that.
Before this video I would'nt have even thought about this mod,but your tuition is so clear and precise Tom you have made it possible,thanks very much.Once again a great video and superb tuition.
Thanks for the video! I decided to get the Barista Gadgets PID because I thought it looked the best out of the options currently available - while not being as intensive of an install as the Gaggiuino. I followed your video as I installed this after work the other day and everything went smooth. As a base, I also copied your temp/PID settings as well. Pulling a shot works perfectly, however I had some issues w/ steam. This started out as a question, but I've been doing some testing as I was writing here and stumbled on the solution to part of my problem. I was having the same issue as others have mentioned - low pressure, temps dropping below 140, etc. The instructions suggest to start steaming at 155c, which I still had those issues. However I decided to try steaming at 150 and that seemed to do the trick to avoid the overheat/shutdown. On my machine, steaming to 150c took 32 seconds. That's typically when I'd start steaming w/ the GCP prior to the PID anyhow. I opened up the steam wand and let it run and to my delight, the temps never dropped below 150c. They did continue to rise before briefly dipping, I'd say it averaged 153c before the PID automatically reverted back to Brew mode. However, not quite the 155-157 range I dialed into settings. So for steaming, this is kinda hit & miss. My hopes was that the PID could set & maintain the steam temps. However it has the same failings as using the GCP steam switch. If you wait too long, it exceeds the temperature limits, shuts off the boiler and you get subpar steam pressure. Worse, it only runs for a total of 90 seconds. This starts when you select Steam Mode so you can't even hold out for the pressure to build up. I understand if the boiler struggles to continue to increase the temperature while I am currently steaming. I'd happily to wait for it to reach the temp range I input, if it would stop before shutting down. Was there another setting that I missed to this? A max-max steam setting?
Hi there! Thanks for your input. Barista Gadgets told me to increase the steam temp setpoint, because I originally had mine too low (140). I think I have it set for 150 or 155 now. That way, it triggers the heating earlier. One thing to remember is, it's a tiny boiler, and no more water is coming in while steaming, so it will eventually lose power as the remaining water turns to steam, and escapes through the wand. I think that's why it's limited to 90 seconds. That time is fine as long as you're prepared ahead of time with your milk in the pitcher. But yes, I have been caught a couple of times too, before I noticed the 90 second limit. Cheers! Tom "Regarding the stemp temperature the Min temp should be about 1-2c less than the Max temp. Doing so will energize the heater sooner when the temperature drops while frothing. An Important tip is to start frothing around 155-156c - before the brew light turns on." Some tips from the maker.
I installed this about 2 weeks ago. A few things I noticed is that even though it says you can do the steam switch on the machine or the steam switch on the PID, they don’t work the same way. Using the PID switch will heat to the steam temp you configured. Using the steam switch on the machine heats up to like 165C and then down all the way to around 140C ish. Also noticed that sometimes after steaming, the temperature would not drop below about 125C until i hit the brew switch for a few seconds. After that it would start dropping to the configured temperature. I just noticed the steam temp difference this morning, so maybe that is also related to the brew temp not dropping after steaming. I would suggest just using the PID switches for selecting brew and steam temps.
Thank you for this video Tom. I hav e his PID on the way and should be here in a few days. I'm really surprised I don't see more videos on this specific PID. Looks way better than what others offer at a better price.
Agreed. I just think the maker needs a little better marketing, like a website for example. Shades has dominated the GCP market, and also has an informative website. But this PID is in my opinion much more modern, and I really like the clever shot counter, and LED for the tank. Cheers!
@@TomsCoffeeCorner Just installed mine. Love it so far. Install was very simple thanks to your video and the clear directions from Barista Gadgets. I am a little unclear on what the PID settings mean exactly so i'll have to do some more research. Maybe an in depth video on what all these settings do?
@@nickzourikian4555 But my comment simply talked about the costs of a retail PID, not how much more Gaggia would charge for one with it. I think they realize it’s better to keep the base product cheaper and make money from add ons and the PID being a non proprietary set of electronics isn’t very high margin.
Great Video Tom, very informative and well explained! As soon as I‘m gonna buy the Gaggia Classic I will install a PID as well. Might be the one from Barista Gadgets!
I'd need an electrician to come in the box. I really apricate videos like this and find them enjoyable but actually doing this would give me an anxiety attack (no exaggeration). That is ultimately why I went the Bambino Plus route.
Thanks for your feedback, but it's really not bad. It comes with a thorough manual, and with this video, it should be pretty easy to follow. At least that's my aim. You don't have to do any wire stripping or anything like that. Just install the pre-fabricated connections. :) The toughest thing was removing a few stubborn connectors, but they acquiesced to my screwdriver.
@@TomsCoffeeCorner I'm sure with the video my wife could install the pid. It is well put together and thorough. As I said, videos like this are great. I just stress out easily over electronics.
Hi Tom. Thanks for the video. I just installed the PID and it works great. Your walkthrough was certainly indispensable. Have you setup a temperature offset yet? I'm thinking of using a temperature probe to get a reading at the group head during a shot and adjusting as needed.
Well, you can either use an offset, or just make the setpoint value higher. I took the default way for now, but let me know what offset you find. I measured myself, but I lost that note of what offset I measured. It might have been around 10 degrees. Cheers!
Thanks for doing this. Now I'm pretty sure I won't. I was wondering how complicated it is to install PID. It looks like you taking apart basically everything inside the Gaggia. Pas 😊
Really the only hard thing is getting at the brew thermostat, which is on the bottom. Therefore, you have to remove the boiler...not a bad mod to do though.
Hello Tom thank you for this video, it's awesome as always! Can you give some feedback on what's the difference in the coffee and taste without the PID and after installing it? Is it really worth the upgrade? Maybe give some rating 1 - 10 before/after :) Thanks and keep up the good work!
I'd say the PID makes the results more consistent, but doesn't guarantee awesome shots. You still need to experiment with temperatures, pressure, and your coffee beans. For me, I'd say lowering the pressure has made the most noticeable difference in getting a more balanced shot, and then you can fine tune it further with the PID. Cheers!
Hi Tom! Thank you for the video, it's very detailed and well-explained. In the manual, I would like to know if there is an explanation on how to set the PID to 93 degrees but measured in the group head? I assumed it was set with the offset function. Also, where exactly were you measuring the temperature for the test you ran in the video? Thank you and cheers!
The temp probe is at the bottom of the boiler which is not quite the same as the group head, but close. Maybe add 2 degrees for an offset would be my guess. Cheers!
It's a dimmer, yes. It affects flow and not directly temperature, although if one limits the flow, the water might get hotter as it is slower going through the thermoblock...
Hey Tom Great video - couldn’t seem to find any stock online, did you get this direct from barista gadgets or was it in stock at the time you ordered it?
Great video, thank you for the wonderful explanation. Do you know if the interface allows you to always keep it in horizontal mode? Having to switch between landscape and portrait depending if you're in the menu or not seems a bit cumbersome
Hi Tom, great video! In Germany Gaggia + PID is around the same price as the Lelit Grace with PID. What would be your choice or would you choose something different? Found your channel today and directly subscribed ;)
Servus, Simon! The Grace is better. It looks way cooler in my opinion, comes with the PID installed and calibrated, has a manometer, and is way more modern in all regards. Also much better cup height. I did a review on the Grace here: th-cam.com/video/pogxzJMoUMs/w-d-xo.html
@@s1mmiki Well they are both capable machines, but the Grace is more consistent, which is better for finding the right temperature and pressure for your bean of choice. I also like the aesthetics better on the Grace, so considering how close they are in price, I'd recommend the Grace every time.
@@TomsCoffeeCorner Great to hear! So the Grace will be my choice. Thanks a lot for your help! Looking forward to watch more of your content 😊 Best regards!
THX for the video, probably will return to it when my delonghi finally gives up as I was aiming for GCP as a next machine. Are the P, I, D settings shown in the video the default ones? On the XMT 7100 PID installed on my EC230 the numbers are totally different (3; 273; 68) But these- were found by the built-in auto-settings mode, not manually. I understand that machines are different, yes, but so much difference...not sure how to find the best solution except for hopefully yet blindfoldedly struggling through this forest of numbers...how much math is sufficient? ) ah, missed the answer...so those were default ones...
Yes, default was 40 for P, 2 for I, and I think 250 for D. The most important one is the proportional gain, which determines how quickly the target is reached. The derivative gain helps to avoid overshooting
I wouldn't really say that. It's pretty well prepared...if you watch the video it should take about an hour to do. But yes, it will require a little patience. Cheers!
Hi there! I would suggest that you use the machine first in its base configuration, then upgrade it. Start with the 9 bar spring, and later you can do the PID as well. Cheers!
Hi Tom awesome video as always. I notice you have preinfusion at 6seconds but your first drop of coffee at 3sec. Would you be able to share more on the preinfusion?
That setting just stalls the shot counter if you shortly stop the extraction and restart. I don’t actually think it’s relevant, because when pre-infusing, one should only stop the pump (can be done with a dimmer) but the solenoid should remain open in my opinion.
@@TomsCoffeeCorner Hi tom, the pre -infusion works great for me. I interduce water for 3 seconds then I turnoff the brew switch to let the puck to absorb the water and after 5 seconds I activat the brew switch again.
I installed the pid kit according to your video. Everything is good. Thank you very much. I have a small question: the temp(boil temp) is set as 103 degree, while I measured the brewing temp which is only 83 degree(after 15 mins of preheating). I am surprised with the huge difference between the boil temp and the brewing temp. Is there something wrong?
@@TomsCoffeeCorner I removed the shower screen and inserted a thermoprobe into one outlet hole of four outlet holes arranged on the dispersion plate. Many people share their parameters, for example, the offset is set between -7 and -10, but my measurement is -20. It is weird.
Hi Tom, This is an excellent video that I had been awaiting for quite a bit of time now. I had the same aesthetics concerns about the different PID kits actually on the market. The only part of the explanations that I am unsure is about the use of the tweezers to glue the timer attachment to the solenoid. The space that you are then working in is very cramped and, at that point, we cannot clearly see the solenoid on the video image. The same goes for your maneuvers when you talk about using tweezers and glue. Is the glue already on the surface of the piece to be attached to the solenoid or does it have to be applied separately?
Those are justified questions. It was really hard for me to film down inside. It’s not actually glue, it’s double-sided tape, which is already attached to the reed switch holder. But because it’s tight down there, it’s best to use a tweezers to get it on the solenoid. If you just open up your GCP, you will find the solenoid attached to the side of your boiler. At that point, it’s pretty obvious where it goes. Just make sure that the bottom of the reed switch holder sits flush with the bottom of the solenoid valve, and you will be good to go. 👍🏻
Dear Tom, thanks for your excellent video. I have just finished installing my kit and I was wondering how pre-infusion does actually work here. Without any noticeable sound variation from the pump I am struggling to understand.
From the directions: "Pre-infusion - Set the hold time for Pre-infusion. In case the user turns off the brew button during the initial brewing process, the timer will hold the count time for xx seconds if the user will not continue the brew process within the “Pre-infusion” time the timer will rest to zero. If the user continues the brew process within the “Pre-infusion” time the timer will continue to count from the time it stopped. Any total brew time above 18-99seconds, the timer display will maintain the last brew time until the next brewing."
Hi Tom I have the same setup as you. That being said I can’t for the life of me figure out how to turn the profile on the lid on. All I can do is pull a manual shot I have my profiles saved but I can’t figure out how to turn them on and use a profile while brewing. Please make a video as the info from barista gadgets and correspondence with them has been confusing to say the least. Not saying it’s their fault more than likely mine but I need a hand please and thank you
Thanks for the video instructions. My machine is stuck at 18 Celsius after installing the PID. Any advice on what is causing this and where I start on troubleshooting? Thanks
18 degrees? I am guessing the temperature probe is correct, but that the relay was not connected to the boiler properly, and that it's therefore not heating.
@@TomsCoffeeCorner Thank you! I opened it up and noticed that the steam thermostat was broken (most likely when I closed the top of the machine). When I used the brew thermostat there to test, the machine does heat up. How is the steam thermostat being used, now I can control the steam temperature with the PID? Can I use the brew thermostat where the steam thermostat should have been? Or do I need to replace the steam thermostat? Thank you!
Hi Tom, thanks for this in depth instructional video. I'm definitely interested in getting this PID. One question- do you think that this PID could be adapted to the previous generation Gaggia Classic?
Hello Tom, I just installed the PID thanks for your recommandation. I have a question Why is your degree Settings at 103 celsius and Not at 93 ? Is there a Offset of 10 degrees ? Do you still use the Same Pid Settings ? Sorry for my english and have a nice day
Yes, there's a pretty large offset. It might be 10 degrees if I remember right. I didn't alter the PID settings, except the P value, I think I raised it just very slightly to experiment. Have fun!
My US model doesn’t hold the temperature very well. I’m having trouble finding the right settings. Any recommendations from anyone who had to tune up the PID. Mine basically drops to 98 from 102. Tried to increase Kp, Ki, Kd but I find it difficult to get the reactivity without overreaching or bouncing.
Great video Tom! Does it matter which order the red and white cables connects to the brew thermostat as the thermostat terminals are not indicative of positive and negative? ( Just a general question and not related to the PID install )
No, that does not matter. I think it even says in the manual that it does not matter. The thermostat acts similar to a resistor, behaving the same regardless of the orientation.
Thank you so much for this video! I installed the device like you said. Did you find any other interesting settings? Is there a workaround for eu models when the machine is turn off after 20min and I turn it back on - it seems the heat time Is again 10min instead of knowing the Temperatur is still the 100°
You can bridge the contacts together on the brew switch. There's two columns of contacts. One for engaging the pump and expansion valve, and the other just resets the 20 minute timer. That's the one on the right. If you bypass the switch, then the timer will be constantly reset, and your machine will not turn off until you do it. Maybe I will make a video on it.
I have a pid installed gaggia classic aswell. It takes ages to heat it properly. 4-5 flushes when porterfilter is on, waiting for at least 15 min. How is your first shot process?
Hi. Does this kit work for the Gaggia EVo Pro 2023 , I'm in the UK so it's the EU version. I'm just starting out so any advice would be great. Thank you! I love your channel.
Good question - I have not tried it on the Evo yet, but it should be the same. I think the Evo just adds different materials in the portafilter and shower plate over the previous models.
Hi ,Tom I have a 2015 ninja coffee machine after seeing your videos I decided to get a new machine cause I love coffee. What do you recommend in a dual expresso and coffee for $500 .thank you for your videos
Hey there! What market are you in? In Europe, you can snag the Sage Barista Express for that price. In the states, you could try this Delonghi combo, with some modifications. Not sure how it performs though. amzn.to/3IvaF1O
Hi Tom! If I set the temperature for steaming, this means that the temperature will be always on that number and, on consequence, the pressure won't go down? Thanks.
@@TomsCoffeeCorner Tom, what a fantastic video you made. I just received my barista gadgets PID. I decided to buy this one because of your video, and now with the kit in my hands, it is even more clear. I'm so looking forward to install it this afternoon. Thank you!!
When I'm done steaming, I do always relase the pressure in the machine by opening wand in machine off mode. Is it reasonable? and why must I refill the boiler?
You refill the boiler after steaming, because as you consume the steam, the heating element will also be turning water into steam, therefore decreasing the water level in the boiler. You want to refill it, first of all because in most machines the heating elements should be submerged in water (GCP admittedly has the heating elements on the outside of the boiler however), and you want the level of water in the boiler at the right amount to start for your next shot.
Can you set a specific steam temperature? Do you have to go into the menu each time you change from steaming to pulling a shot to adjust the temperature?
Thank you Tom! I've just. purchased it based on your video, I'm looking forward to installing and thank you for creating a very clear guide for us Gaggia lovers :)@@TomsCoffeeCorner
I noticed that you set the brewing temperature as 103 rather than 95 and you initiated the steam by pressing the button at the back of display unit. Does it mean this kit has an offset of 8 degree and I cannot use the customized steaming temperature by press the stock steam button on the GCP?
You can still use the steam button in the GCP. That works parallel to the PID unit, since we did not remove the steam thermostat. As for the brew temp, you can either set the setpoint at 103 degrees like I did, with an offset of 0, or you can set an offset, and then the setpoint temperature will be closer to what's actually at the brew head. You just have to experiment a little. Cheers!
@@TomsCoffeeCorner Thank u very much. Actually, I just wander if I can leave the buttons of kit idle once I finish setting all the parameters and it also ensures a good control of steam temp by the stock steam button (the stock team button can also initial the PID controlling). I believe it would bring more neat appearance since the display unit can be embedded in the rectangular hole (pre-cut) of GCP or be attached to the front side of GCP through a drilled cable hole. Even though it has to keep both control manners of steam, I don't think it is a best idea to arrange the buttons on the back of the display unit and look forward to adjusting the position of buttons on the front or side surface of kit in the next version by baristagadget.
Hi Tom! Wonder if you can make a review of the Ariete Moderna 1318? Ariete is owned by De'Longhi and the Ariete Moderna 1318 looks like a sibling to the DeLongi Dedica but with a pressure gauge on it?
That model does not have a manometer - perhaps you mean a different one? I really prefer to review established models, and I have never heard of Ariete. Cheers!
@@TomsCoffeeCorner that's strange because in this TH-cam advert: th-cam.com/video/NmpMHVIhLHg/w-d-xo.html They say it has a nanometer? I know it's not a known brand, but that is also why it puzzles me. But due to that DeLongi owns it makes it more interesting if it worth looking at or if it is just carp and on the plus side there are no in depth reviews on it so you would be more or less alone to have one if you would do a review on it?
@@123Ryanist Hmm, the one in the video is different than the one I find on Amazon with that name. Maybe it is mislabeled on the YT video. Feel free to send me an Amazon link if you can find it. Cheers!
Your steaming note says that you can use the PID or the Steam Switch for steaming but I noticed you used the PID. When using the Steam Switch will you still achive the steam settings entered into the PID? Also, how does the pre-infusion fuction work?
You can use either the PID, or the steam switch for steaming. If you use the original switch, it will heat until reaching the still remaining steam thermostat. If you use the PID to steam, then the PID will control the temp. I have to look into the pre-infusion setting.
@@TomsCoffeeCorner I'd be interested to see how the pre-infusion functionality works once you look into it. From the instructions provided, it didn't make much sense to me. It talked about turning off the brew switch and it continuing the brew timer if you turned it back on within the pre-infusion time set. It sounds more like a failsafe if you accidentally turn off power while pre-infusing using a dimmer? I don't have a dimmer installed in mine, so I use the "poor-man's pre-infusion" method as Lance Hendrick calls it, which is open the steam valve slightly while brewing to divert water flow and pre-infuse. Using that method, the pre-infusion time counts towards your overall brew time.
@@ForerunnerChief I got an answer from the developer. This setting just bridges the pause of stopping the pump for pre-infusion, so that the pause is not counted in the shot timer. That's it. The PID has no control over the pump or the solenoid - just over the heating.
Well, they are two different things. The PID controls the temperature of course, and the dimmer controls the pump frequency, affecting the flow. I would recommend the PID and the nine bar spring over the dimmer, because many dimmers do not behave linearly. Mine is starting to go kaput, in fact.
@@TomsCoffeeCorner exactly what I wanted to know. Thank you Tom I became a big fan about 8 months ago when I saw your video over the Delonghi ecp3420. You got some great videos keep it up!
Is that a baratza grinder you have back there? Having trouble with my baratza sette 270. It makes a hell of a mess when grinding. My guess, is grinded coffee is getting electrostatic charge. Do you have any ideea what i could to do prevent it, or does this even happend to you at all?
hello, Are the baristagadgets springs calibrated correctly? have you tried them? do you recommend them? since you do the test with those from Shades of Coffee. thank you
Hey Tom , so you inspired me to buy a brand new Gaggia Classic Pro Eco . I also bought the Barista Gadgets PID control system and the dimmer flow control , I installed that and the upgraded silicone "O" ring with the IMS screen . But I have watched your video and you go into some of the PID programming , but not on the PID option in the settings menu . So I do not know what the KP , KI or KD setting are for , or what they mean and most of all how I should configure them . I could use some help if you know !!! Thanks
Thanks Tom , but I'm new to this , so what is the proportional gain ? How do I adjust it ? And why would I adjust it ? Thanks for your assistance !!!!@@TomsCoffeeCorner
The proportional gain is the main gain of the feedback loop. The D gain helps with not overshooting the target (oscillations), and the I helps the P if not being at the target for a long time. This is explained in a video here: th-cam.com/video/qKy98Cbcltw/w-d-xo.html @@roytromb_strength
Well, I think the Dream is ugly, so I wouldn't get that one. But that's just me. :) In all honestly, I would recommend buying a machine though that has a PID built in, because the aesthetics are better (and no machine warranty issues). What about the Lelit Grace?
Do you still use Dimmer mod with this PID. I thought the PID has pre-infusion. Does Dimmer mod provide separate flow control? Is Dimmer mod necessary if someone already has PID.
The PID does not do pre-infusion. It just won't reset the timer if you cut the pump off, then back on. So yes, the dimmer could still be interesting. But honestly I'm actually satisfied with just using the 9 bar spring most of the time.
@@TomsCoffeeCorner Thanks Tom. Recently I bought PID controller based on your product review and recommendation. The GCP sits in my dad's house and he didn't use it for long time until I installed PID. When I told him about Dimmer mod, he said that the espresso is already good with PID. So I wanted to hear your opinion. I think the Dimmer itself is discontinued from amazon (US link you provided).
Hey Tom I just finished adding the pid but the light to indicate that the water has reached its temperature on the gaggia seems to flicker and never stops, any ideas on why this is?
Hi Juan. The "flickering" that you're noticing is the PID at work. Now that it is PID controlled, the heating is much more filigrane. When the light goes out, the element is heating. Before, the heating element would heat until the thermostat was met, and then the light would come on, until the temperature went down below the threshold. But that 2 point system is not as accurate as how your temperature is being controlled now. Hope that helps.
@@dshafrowith single boiler machines like the Gaggia Classic Pro, you always have to prime the pump after steaming milk. Every single boiler machine requires this. Just a simple flush from the group head for a few seconds will fill it back up. Whole Latte Love and other TH-cam channels have great videos discussing why it's so important for single boiler machines and they show you how to do it. In the Gaggia Classic Pro video section on Whole Latte Love they have a good video on tips and tricks and this is included. The boiler isn't empty, by the way. Only a few inches from the top are exposed but this is enough empty space to impact the life of the heating element if you continue to heat it up the next time with a big gap like that. Priming the pump fills it back up to the top for your next brew.
Hi Tom, can I ask? I recently bought off Gaggiadirect a Classic from 2019. The brew temperature never gets higher than 77, and I reported this to the Gaggia direct. He replied with "our machines are all set at 70-90 celsius" This is news to me, and my coffee is now awful but was ok the 1st two days after receiving my Gaggia Classic 2019. He wouldn't suggest repairing but instead offered full refund if I sent it back. Do you happen to have a suggestion? Or should I send it back. I am really sad today, thanks.
@@TomsCoffeeCorner Hi, hanks for replying. I hit the brew switch and purged into a meal pitcher. The temp always stayed under 80c upon immediately measuring the temp. A Gaggia salesman told me their machines are set at between 70-90 celsius. I did many tests and the water is never ever above 80 celsius.
Well, the Gaggiuino mod looks really cool, but I have not found the time to source the parts and do the install. It seems extremely involved, and I heard putting the SW on the board can require some debugging, too.
What happens is actually that the timer will keep timing, if you switch off the brew button during a manual pre-infusion phase. So, it's a manual process, but the timer will keep counting rather than stopping and re-initializing.
Some problems about this machine. 1. The steamer drips all the time, espesially while the espresso shot is taken. 2. 100ml boiler is not enought to steam the milk. While steaming the milk the heat light turns off, meaning, the steam turns to cold. The hot water is allready finishes far before the milk steaming.
You're not wrong. But the steam wand doesn't always drip. It depends on descaling, and maybe some luck. I know that quite a few people have had to replace it though. As for the milk steaming, just wait 10 seconds, then start steaming. Don't wait for the light. That way it will keep steaming long enough to froth the milk. Cheers!
The steam wand has condensed water inside from your last brew session. It cools and then when you heat the machine back up it drips out. Most people think they have a leak but they actually don't. It's just this residual water dripping out of the wand. Here is the test that the technicians use to determine if your steam valve is actually bad: Turn on your machine and warm it up. Then flip both the brew and steam buttons on simultaneously but do not open your steam knob. Keep it closed. This forces hot water out of the steam wand but you are keeping it closed for this first step. If nothing comes out of your wand and it's not bubbling, then your valve is fine. Next, open the valve long enough to let a full stream of hot water out and then close it tightly again. If the flow of hot water through the wand completely stops and there's no bubbling, then your valve is fine. In the Gaggia Classic Pro technical support section on Whole Latte Love they have some videos about how to diagnose steam valve issues and this is the test they do.
You're a bit late to the party installing a PID on a Gaggia, I thought you woudl have done this ages ago. it would be cool to see you do a the Gaggiuino Mod which I might o if I buy a new Gaggia machine, my 2006 classic has been spec out with the Mr Shades, PID, Box and pressure gauge with the dimmer mod so its a failry manual setup.
I waited until I found a PID to my liking. The Shades PID and every other one I know are missing shot timers, and their aesthetics are not pleasing to me.
@@jamesmac6102 That's right. The Shades and most other kits use that generic PID controller, that looks like it's from the 80's. The one I installed has a nice graphical display and shot counter included.
It stands for Proportional Integral Derivative. It's an algorithm that monitors and controls the temperature of a heating unit during use. It bypasses the basic on/off function of a simple thermostat and uses the heating element in real time to control the temperatures.
This kit can be installed on any Gaggia Classic with a boiler like this, however the power tapping may vary based on machine age.
The kit should work with any machine that has a solenoid valve and an M4 thread in the boiler for the temperature probe, such as the Rancilio Silvia.

From the maker:
"When customers ask us about compatibility, our easiest answer for them is what their boiler looks like, is it like in your video?. If so the PID kit will fit their machine.
Regarding other machines (such as the Silvia): if the boiler has a M4 thread for the temperature sensor and a solenoid valve for the timer the kit will be compatible."
I want to buy it. Please give me the link to buy
I plan to purchase the Gaggia Classic Pro in the future. I appreciate that you make these videos as I will watch it again once I am able to buy my dream machine.
I just completed this upgrade following your instructions as well as the ones included. It was just as easy as it looks here and anyone can do it. I also like the included tank light, very useful.
Awesome! Thanks for posting your success!
I just received my new Gaggia Classic Evo Pro, and now I’m thinking of tearing it apart! Haven’t even pulled one shot of espresso yet LOL! But this looks fun!
Haha, I would really suggest using it first and getting a feeling for it, before upgrading. It will be more satisfying that way. Cheers!
Thank you so much for making this video. It made me realise that modifying the Gaggia with PID temperature control is absolutely not for me! If I attempted this I just know something would go wrong. You have the patience of a saint and a useful tool kit, I have neither!
I want a machine with PID control so I’ll buy something else.
You could consider a Lelit Grace, or MiiCoffee Apex.
@@TomsCoffeeCorner Thank you, very helpful suggestions.
My current favourite (at about £1,300, my budget is creeping up!) is the Fracino Piccino PID. I haven't looked at either of your suggestions yet so I'll get onto that.
If I didn't know he was serious, I would think this is an SNL skit.
Before this video I would'nt have even thought about this mod,but your tuition is so clear and precise Tom you have made it possible,thanks very much.Once again a great video and superb tuition.
Just installed mine, incredibly helpful video👌👌👌
Awesome, enjoy!
A service to humanity you've done there, Tom. If I'd done this to my Lelit N years ago I have kept it.
Thanks for the video! I decided to get the Barista Gadgets PID because I thought it looked the best out of the options currently available - while not being as intensive of an install as the Gaggiuino. I followed your video as I installed this after work the other day and everything went smooth. As a base, I also copied your temp/PID settings as well. Pulling a shot works perfectly, however I had some issues w/ steam.
This started out as a question, but I've been doing some testing as I was writing here and stumbled on the solution to part of my problem. I was having the same issue as others have mentioned - low pressure, temps dropping below 140, etc. The instructions suggest to start steaming at 155c, which I still had those issues. However I decided to try steaming at 150 and that seemed to do the trick to avoid the overheat/shutdown.
On my machine, steaming to 150c took 32 seconds. That's typically when I'd start steaming w/ the GCP prior to the PID anyhow. I opened up the steam wand and let it run and to my delight, the temps never dropped below 150c. They did continue to rise before briefly dipping, I'd say it averaged 153c before the PID automatically reverted back to Brew mode. However, not quite the 155-157 range I dialed into settings.
So for steaming, this is kinda hit & miss. My hopes was that the PID could set & maintain the steam temps. However it has the same failings as using the GCP steam switch. If you wait too long, it exceeds the temperature limits, shuts off the boiler and you get subpar steam pressure. Worse, it only runs for a total of 90 seconds. This starts when you select Steam Mode so you can't even hold out for the pressure to build up.
I understand if the boiler struggles to continue to increase the temperature while I am currently steaming. I'd happily to wait for it to reach the temp range I input, if it would stop before shutting down. Was there another setting that I missed to this? A max-max steam setting?
Hi there! Thanks for your input. Barista Gadgets told me to increase the steam temp setpoint, because I originally had mine too low (140). I think I have it set for 150 or 155 now. That way, it triggers the heating earlier. One thing to remember is, it's a tiny boiler, and no more water is coming in while steaming, so it will eventually lose power as the remaining water turns to steam, and escapes through the wand. I think that's why it's limited to 90 seconds. That time is fine as long as you're prepared ahead of time with your milk in the pitcher. But yes, I have been caught a couple of times too, before I noticed the 90 second limit. Cheers! Tom
"Regarding the stemp temperature the Min temp should be about 1-2c less than the Max temp. Doing so will energize the heater sooner when the temperature drops while frothing.
An Important tip is to start frothing around 155-156c - before the brew light turns on." Some tips from the maker.
Thanks to your video . I finally had the courage to buy and install the PID kit . No more h2o surfing
I have been waiting for a great PID that looks good and functions too, AND I have a clear understanding of how to install it. Thank you so much.
The barista gadgets pid is very nice and love the shot timer they added. Very easy to install by following their instructions
That is a very clean and functional looking PID. Also was a great video demonstration!
best coffe channel
Very kind of you, thanks!
I installed this about 2 weeks ago. A few things I noticed is that even though it says you can do the steam switch on the machine or the steam switch on the PID, they don’t work the same way. Using the PID switch will heat to the steam temp you configured. Using the steam switch on the machine heats up to like 165C and then down all the way to around 140C ish. Also noticed that sometimes after steaming, the temperature would not drop below about 125C until i hit the brew switch for a few seconds. After that it would start dropping to the configured temperature. I just noticed the steam temp difference this morning, so maybe that is also related to the brew temp not dropping after steaming. I would suggest just using the PID switches for selecting brew and steam temps.
Are you still satisfied With the kit?
Thank you for this video Tom. I hav e his PID on the way and should be here in a few days. I'm really surprised I don't see more videos on this specific PID. Looks way better than what others offer at a better price.
Agreed. I just think the maker needs a little better marketing, like a website for example. Shades has dominated the GCP market, and also has an informative website. But this PID is in my opinion much more modern, and I really like the clever shot counter, and LED for the tank. Cheers!
@@TomsCoffeeCorner Just installed mine. Love it so far. Install was very simple thanks to your video and the clear directions from Barista Gadgets. I am a little unclear on what the PID settings mean exactly so i'll have to do some more research. Maybe an in depth video on what all these settings do?
I thought I would be able to comment first but tom beat me to it 😅
Such a cute PID!!!!!
I ordered the barrista gadgets pid based on this vid and can't wait to instal it.
Soooo helpful, terrific walk through. Thanks Tom!
Glad it was helpful! Have fun! Tom
if everyone wants a PID on the gaggia. Why doesn't gaggia make a "Gaggia PID Pro". It'll fly off the shelves?
It WOULD fly off the shelves. I don't know why they don't to it, either.
@@TomsCoffeeCorner Because then the Gaggia will cost $1200 or more. See the Ranchilio Silvia as an example.
@@Ron-tr2wrdon’t the PID installation kits cost like $50? I saw the barista express one for that amount.
@@blakeskolnick6750 Don’t iPhones cost a fraction of their retail prices - to manufacture?
@@nickzourikian4555 But my comment simply talked about the costs of a retail PID, not how much more Gaggia would charge for one with it. I think they realize it’s better to keep the base product cheaper and make money from add ons and the PID being a non proprietary set of electronics isn’t very high margin.
Very nice set up, I love the clean connections to the PID. The interface is super nice as well. I wish this was out when I installed my PID
Thanks Tom, just ordered this kit from Barista Gadgets to fit on my new unboxed GCP.
Hope you enjoy it! Have fun experimenting!
Great Video Tom, very informative and well explained! As soon as I‘m gonna buy the Gaggia Classic I will install a PID as well. Might be the one from Barista Gadgets!
WOW,You are very professional.
Excellent video!
If this was available for Germany I´d buy it in a heartbeat!
I read an Etsy review that you can message the shop owner and have them unlock your country for delivery!
Quality machine, well done inside too
This is really the Supra mk4 of coffee machines
I'd need an electrician to come in the box. I really apricate videos like this and find them enjoyable but actually doing this would give me an anxiety attack (no exaggeration). That is ultimately why I went the Bambino Plus route.
Thanks for your feedback, but it's really not bad. It comes with a thorough manual, and with this video, it should be pretty easy to follow. At least that's my aim.
You don't have to do any wire stripping or anything like that. Just install the pre-fabricated connections. :) The toughest thing was removing a few stubborn connectors, but they acquiesced to my screwdriver.
@@TomsCoffeeCorner I'm sure with the video my wife could install the pid. It is well put together and thorough. As I said, videos like this are great. I just stress out easily over electronics.
Hi Tom. Thanks for the video. I just installed the PID and it works great. Your walkthrough was certainly indispensable. Have you setup a temperature offset yet? I'm thinking of using a temperature probe to get a reading at the group head during a shot and adjusting as needed.
Well, you can either use an offset, or just make the setpoint value higher. I took the default way for now, but let me know what offset you find. I measured myself, but I lost that note of what offset I measured. It might have been around 10 degrees. Cheers!
Just got to test this out. I also had a 10 degree C difference and 12 degree temperature drop within a 25 second extraction.
Thanks for doing this. Now I'm pretty sure I won't. I was wondering how complicated it is to install PID. It looks like you taking apart basically everything inside the Gaggia. Pas 😊
Really the only hard thing is getting at the brew thermostat, which is on the bottom. Therefore, you have to remove the boiler...not a bad mod to do though.
can you make a video tutorial on installing PID on delonghi ecp? Thank u so much
Hello Tom thank you for this video, it's awesome as always! Can you give some feedback on what's the difference in the coffee and taste without the PID and after installing it? Is it really worth the upgrade? Maybe give some rating 1 - 10 before/after :)
Thanks and keep up the good work!
I'd say the PID makes the results more consistent, but doesn't guarantee awesome shots. You still need to experiment with temperatures, pressure, and your coffee beans. For me, I'd say lowering the pressure has made the most noticeable difference in getting a more balanced shot, and then you can fine tune it further with the PID. Cheers!
I installed the PID and can not go back!. The espresso taste is night and day.
Hi Tom! Thank you for the video, it's very detailed and well-explained. In the manual, I would like to know if there is an explanation on how to set the PID to 93 degrees but measured in the group head? I assumed it was set with the offset function. Also, where exactly were you measuring the temperature for the test you ran in the video? Thank you and cheers!
The temp probe is at the bottom of the boiler which is not quite the same as the group head, but close. Maybe add 2 degrees for an offset would be my guess. Cheers!
Great vid. What is the dial on the side? A pump dimmer? Do you need that now that you have a PID?
It's a dimmer, yes. It affects flow and not directly temperature, although if one limits the flow, the water might get hotter as it is slower going through the thermoblock...
Hey Tom
Great video - couldn’t seem to find any stock online, did you get this direct from barista gadgets or was it in stock at the time you ordered it?
The seller is still waiting for more stock to come in, I'm afraid. Hopefully in the next couple weeks.
There is 3 of the new stock left (nr 4 was just shipped this evening)l. It is selling as hot cakes.
Great video, thank you for the wonderful explanation. Do you know if the interface allows you to always keep it in horizontal mode? Having to switch between landscape and portrait depending if you're in the menu or not seems a bit cumbersome
Yes, it also works in horizontal mode.
Hi Tom, great video! In Germany Gaggia + PID is around the same price as the Lelit Grace with PID. What would be your choice or would you choose something different? Found your channel today and directly subscribed ;)
Servus, Simon! The Grace is better. It looks way cooler in my opinion, comes with the PID installed and calibrated, has a manometer, and is way more modern in all regards. Also much better cup height. I did a review on the Grace here: th-cam.com/video/pogxzJMoUMs/w-d-xo.html
@@TomsCoffeeCorner Thanks a lot for your fast reply! So you would also say, that the coffee produced by the Grace is better?
Thanks a lot 😊
@@s1mmiki Well they are both capable machines, but the Grace is more consistent, which is better for finding the right temperature and pressure for your bean of choice. I also like the aesthetics better on the Grace, so considering how close they are in price, I'd recommend the Grace every time.
@@TomsCoffeeCorner Great to hear! So the Grace will be my choice. Thanks a lot for your help! Looking forward to watch more of your content 😊
Best regards!
@@s1mmiki I would be careful with that 57mm portafilter, you'll be stuck with limited options in the long run
THX for the video, probably will return to it when my delonghi finally gives up as I was aiming for GCP as a next machine.
Are the P, I, D settings shown in the video the default ones? On the XMT 7100 PID installed on my EC230 the numbers are totally different (3; 273; 68) But these- were found by the built-in auto-settings mode, not manually. I understand that machines are different, yes, but so much difference...not sure how to find the best solution except for hopefully yet blindfoldedly struggling through this forest of numbers...how much math is sufficient? )
ah, missed the answer...so those were default ones...
Yes, default was 40 for P, 2 for I, and I think 250 for D. The most important one is the proportional gain, which determines how quickly the target is reached. The derivative gain helps to avoid overshooting
More a job for a skilled technician or a person who has a deep knowledge about the inner parts of an espresso machine.
I wouldn't really say that. It's pretty well prepared...if you watch the video it should take about an hour to do. But yes, it will require a little patience. Cheers!
Can i use this process for my shades of coffee pid controller?
Hi! I finally decided to purchase my first GCP and it will arrive today. Do you recommend this mod for a beginner getting into the hobby?
Hi there! I would suggest that you use the machine first in its base configuration, then upgrade it. Start with the 9 bar spring, and later you can do the PID as well. Cheers!
@@TomsCoffeeCorner Thanks for the input! I'll try that then and work my way through.
Hi Tom awesome video as always. I notice you have preinfusion at 6seconds but your first drop of coffee at 3sec. Would you be able to share more on the preinfusion?
That setting just stalls the shot counter if you shortly stop the extraction and restart. I don’t actually think it’s relevant, because when pre-infusing, one should only stop the pump (can be done with a dimmer) but the solenoid should remain open in my opinion.
@@TomsCoffeeCorner Hi tom, the pre -infusion works great for me. I interduce water for 3 seconds then I turnoff the brew switch to let the puck to absorb the water and after 5 seconds I activat the brew switch again.
@@jamesmac6102 Ok, good to know! Maybe I will try that out once.
I installed the pid kit according to your video. Everything is good. Thank you very much. I have a small question: the temp(boil temp) is set as 103 degree, while I measured the brewing temp which is only 83 degree(after 15 mins of preheating). I am surprised with the huge difference between the boil temp and the brewing temp. Is there something wrong?
How did you measure the brew temp? Of course the water coming out of the brew group will not be as hot as the temp probe, therefore the offset.
@@TomsCoffeeCorner I removed the shower screen and inserted a thermoprobe into one outlet hole of four outlet holes arranged on the dispersion plate. Many people share their parameters, for example, the offset is set between -7 and -10, but my measurement is -20. It is weird.
Hi Tom,
This is an excellent video that I had been awaiting for quite a bit of time now. I had the same aesthetics concerns about the different PID kits actually on the market. The only part of the explanations that I am unsure is about the use of the tweezers to glue the timer attachment to the solenoid. The space that you are then working in is very cramped and, at that point, we cannot clearly see the solenoid on the video image. The same goes for your maneuvers when you talk about using tweezers and glue. Is the glue already on the surface of the piece to be attached to the solenoid or does it have to be applied separately?
Those are justified questions. It was really hard for me to film down inside. It’s not actually glue, it’s double-sided tape, which is already attached to the reed switch holder. But because it’s tight down there, it’s best to use a tweezers to get it on the solenoid. If you just open up your GCP, you will find the solenoid attached to the side of your boiler. At that point, it’s pretty obvious where it goes. Just make sure that the bottom of the reed switch holder sits flush with the bottom of the solenoid valve, and you will be good to go. 👍🏻
Thanks for the follow-up!!!😊
Did you have to buy double sided tape or anything else ?
Dear Tom, thanks for your excellent video. I have just finished installing my kit and I was wondering how pre-infusion does actually work here. Without any noticeable sound variation from the pump I am struggling to understand.
From the directions:
"Pre-infusion - Set the hold time for Pre-infusion. In case the user turns off the brew button during the initial brewing process, the timer will hold the count time for xx seconds if the user will not continue the brew process within the “Pre-infusion” time the timer will rest to zero. If the user continues the brew process within the “Pre-infusion” time the timer will continue to count from the time it stopped. Any total brew time above 18-99seconds, the timer display will maintain the last brew time until the next brewing."
So basically the unit doesn't do any pre infusion, but rather the timer can account for when you do it manually?? I'm confused.
Hi Tom I have the same setup as you. That being said I can’t for the life of me figure out how to turn the profile on the lid on. All I can do is pull a manual shot I have my profiles saved but I can’t figure out how to turn them on and use a profile while brewing. Please make a video as the info from barista gadgets and correspondence with them has been confusing to say the least. Not saying it’s their fault more than likely mine but I need a hand please and thank you
For something as useful as this, they should made in finger friendly LOL
Thanks for the video instructions. My machine is stuck at 18 Celsius after installing the PID. Any advice on what is causing this and where I start on troubleshooting? Thanks
18 degrees? I am guessing the temperature probe is correct, but that the relay was not connected to the boiler properly, and that it's therefore not heating.
@@TomsCoffeeCorner Thank you! I opened it up and noticed that the steam thermostat was broken (most likely when I closed the top of the machine). When I used the brew thermostat there to test, the machine does heat up.
How is the steam thermostat being used, now I can control the steam temperature with the PID? Can I use the brew thermostat where the steam thermostat should have been? Or do I need to replace the steam thermostat?
Thank you!
Hi Tom, thanks for this in depth instructional video. I'm definitely interested in getting this PID. One question- do you think that this PID could be adapted to the previous generation Gaggia Classic?
I am thinking that the screw diameter for the thermostat was the same, so I think so. But I will get some info from the developer and let you know.
how does the factory let you make changes to the coffee machine great job I always follow you
This will void the warranty...
Hello Tom,
I just installed the PID thanks for your recommandation. I have a question Why is your degree Settings at 103 celsius and Not at 93 ? Is there a Offset of 10 degrees ? Do you still use the Same Pid Settings ? Sorry for my english and have a nice day
Yes, there's a pretty large offset. It might be 10 degrees if I remember right. I didn't alter the PID settings, except the P value, I think I raised it just very slightly to experiment. Have fun!
My US model doesn’t hold the temperature very well. I’m having trouble finding the right settings. Any recommendations from anyone who had to tune up the PID.
Mine basically drops to 98 from 102. Tried to increase Kp, Ki, Kd but I find it difficult to get the reactivity without overreaching or bouncing.
Great video Tom! Does it matter which order the red and white cables connects to the brew thermostat as the thermostat terminals are not indicative of positive and negative? ( Just a general question and not related to the PID install )
No, that does not matter. I think it even says in the manual that it does not matter. The thermostat acts similar to a resistor, behaving the same regardless of the orientation.
Thank you so much for this video! I installed the device like you said. Did you find any other interesting settings? Is there a workaround for eu models when the machine is turn off after 20min and I turn it back on - it seems the heat time
Is again 10min instead of knowing the Temperatur is still the 100°
You can bridge the contacts together on the brew switch. There's two columns of contacts. One for engaging the pump and expansion valve, and the other just resets the 20 minute timer. That's the one on the right. If you bypass the switch, then the timer will be constantly reset, and your machine will not turn off until you do it. Maybe I will make a video on it.
Review the gran gaggia deluxe please
I have a pid installed gaggia classic aswell. It takes ages to heat it properly. 4-5 flushes when porterfilter is on, waiting for at least 15 min. How is your first shot process?
Hi. Does this kit work for the Gaggia EVo Pro 2023 , I'm in the UK so it's the EU version. I'm just starting out so any advice would be great. Thank you! I love your channel.
Good question - I have not tried it on the Evo yet, but it should be the same. I think the Evo just adds different materials in the portafilter and shower plate over the previous models.
Hello, is it available in france without customer taxes please? Is it worth to add this to the gaggia classic pro?
Hi ,Tom I have a 2015 ninja coffee machine after seeing your videos I decided to get a new machine cause I love coffee. What do you recommend in a dual expresso and coffee for $500 .thank you for your videos
Hey there! What market are you in? In Europe, you can snag the Sage Barista Express for that price. In the states, you could try this Delonghi combo, with some modifications. Not sure how it performs though. amzn.to/3IvaF1O
Great video Tom! Just wanted to know if this mod would work on the pre-2015 gaggia classic?
Yes, because the thermostat screw hole is the same. This even works with Rancilio Silvia. Cheers!
Perfect, thanks for the reply!
Hi Tom! If I set the temperature for steaming, this means that the temperature will be always on that number and, on consequence, the pressure won't go down? Thanks.
Sorry, not real sure what you mean? Yes, it will follow the temp that you set. But it only stays in steam mode for 90 seconds max. Cheers!
@@TomsCoffeeCorner Tom, what a fantastic video you made. I just received my barista gadgets PID. I decided to buy this one because of your video, and now with the kit in my hands, it is even more clear. I'm so looking forward to install it this afternoon.
Thank you!!
When I'm done steaming, I do always relase the pressure in the machine by opening wand in machine off mode. Is it reasonable? and why must I refill the boiler?
You refill the boiler after steaming, because as you consume the steam, the heating element will also be turning water into steam, therefore decreasing the water level in the boiler. You want to refill it, first of all because in most machines the heating elements should be submerged in water (GCP admittedly has the heating elements on the outside of the boiler however), and you want the level of water in the boiler at the right amount to start for your next shot.
Can you set a specific steam temperature? Do you have to go into the menu each time you change from steaming to pulling a shot to adjust the temperature?
Yes, you set a steam range, upper and lower limits. And no, the temperatures are in the memory of the unit. You just set them once.
Thank you Tom! I've just. purchased it based on your video, I'm looking forward to installing and thank you for creating a very clear guide for us Gaggia lovers :)@@TomsCoffeeCorner
Hey there; thanks for the video. I have one on order. Any tools/tape etc I should order ? Thanks
You betcha! This kit comes with everything you need. Cheers!
I noticed that you set the brewing temperature as 103 rather than 95 and you initiated the steam by pressing the button at the back of display unit. Does it mean this kit has an offset of 8 degree and I cannot use the customized steaming temperature by press the stock steam button on the GCP?
You can still use the steam button in the GCP. That works parallel to the PID unit, since we did not remove the steam thermostat.
As for the brew temp, you can either set the setpoint at 103 degrees like I did, with an offset of 0, or you can set an offset, and then the setpoint temperature will be closer to what's actually at the brew head. You just have to experiment a little. Cheers!
@@TomsCoffeeCorner Thank u very much. Actually, I just wander if I can leave the buttons of kit idle once I finish setting all the parameters and it also ensures a good control of steam temp by the stock steam button (the stock team button can also initial the PID controlling). I believe it would bring more neat appearance since the display unit can be embedded in the rectangular hole (pre-cut) of GCP or be attached to the front side of GCP through a drilled cable hole. Even though it has to keep both control manners of steam, I don't think it is a best idea to arrange the buttons on the back of the display unit and look forward to adjusting the position of buttons on the front or side surface of kit in the next version by baristagadget.
I’m attempting on my pre 2015 model but the connections are different to the power switches
Which model do you have? US or EU?
Hi Tom!
Wonder if you can make a review of the Ariete Moderna 1318?
Ariete is owned by De'Longhi and the Ariete Moderna 1318 looks like a sibling to the DeLongi Dedica but with a pressure gauge on it?
That model does not have a manometer - perhaps you mean a different one? I really prefer to review established models, and I have never heard of Ariete. Cheers!
@@TomsCoffeeCorner that's strange because in this TH-cam advert: th-cam.com/video/NmpMHVIhLHg/w-d-xo.html
They say it has a nanometer?
I know it's not a known brand, but that is also why it puzzles me. But due to that DeLongi owns it makes it more interesting if it worth looking at or if it is just carp and on the plus side there are no in depth reviews on it so you would be more or less alone to have one if you would do a review on it?
@@123Ryanist Hmm, the one in the video is different than the one I find on Amazon with that name. Maybe it is mislabeled on the YT video. Feel free to send me an Amazon link if you can find it. Cheers!
Does instruction for the rancilio Silvia come with the kid? Or do you buy a specifik PID kit for that machine?
No, but the principles should be the same. The switch might be slightly different though.
Your steaming note says that you can use the PID or the Steam Switch for steaming but I noticed you used the PID. When using the Steam Switch will you still achive the steam settings entered into the PID? Also, how does the pre-infusion fuction work?
You can use either the PID, or the steam switch for steaming. If you use the original switch, it will heat until reaching the still remaining steam thermostat. If you use the PID to steam, then the PID will control the temp. I have to look into the pre-infusion setting.
@@TomsCoffeeCorner I'd be interested to see how the pre-infusion functionality works once you look into it. From the instructions provided, it didn't make much sense to me. It talked about turning off the brew switch and it continuing the brew timer if you turned it back on within the pre-infusion time set. It sounds more like a failsafe if you accidentally turn off power while pre-infusing using a dimmer? I don't have a dimmer installed in mine, so I use the "poor-man's pre-infusion" method as Lance Hendrick calls it, which is open the steam valve slightly while brewing to divert water flow and pre-infuse. Using that method, the pre-infusion time counts towards your overall brew time.
@@ForerunnerChief I got an answer from the developer. This setting just bridges the pause of stopping the pump for pre-infusion, so that the pause is not counted in the shot timer. That's it. The PID has no control over the pump or the solenoid - just over the heating.
How necessary would it still be to install the dimmer mod?
Well, they are two different things. The PID controls the temperature of course, and the dimmer controls the pump frequency, affecting the flow. I would recommend the PID and the nine bar spring over the dimmer, because many dimmers do not behave linearly. Mine is starting to go kaput, in fact.
@@TomsCoffeeCorner exactly what I wanted to know. Thank you Tom I became a big fan about 8 months ago when I saw your video over the Delonghi ecp3420. You got some great videos keep it up!
When using water from steam wand, is shot timer activated? Thanks.
No, it’s the brew button that activates the shot timer. It works by noticing when the solenoid to the brew group valve is opened.
Is that a baratza grinder you have back there?
Having trouble with my baratza sette 270.
It makes a hell of a mess when grinding. My guess, is grinded coffee is getting electrostatic charge. Do you have any ideea what i could to do prevent it, or does this even happend to you at all?
You could try RDT. Some coffees are just super staticky though.
hello,
Are the baristagadgets springs calibrated correctly? have you tried them? do you recommend them? since you do the test with those from Shades of Coffee. thank you
They are the same as the Shades of Coffee
Thanks for that answer James!
Hey Tom , so you inspired me to buy a brand new Gaggia Classic Pro Eco . I also bought the Barista Gadgets PID control system and the dimmer flow control , I installed that and the upgraded silicone "O" ring with the IMS screen . But I have watched your video and you go into some of the PID programming , but not on the PID option in the settings menu . So I do not know what the KP , KI or KD setting are for , or what they mean and most of all how I should configure them . I could use some help if you know !!! Thanks
Hi there! This model comes with the PID settings already set up. All I did was increase my Proportional gain from 40 to 50. Cheers!
Thanks Tom , but I'm new to this , so what is the proportional gain ? How do I adjust it ? And why would I adjust it ? Thanks for your assistance !!!!@@TomsCoffeeCorner
please respond to this question, I also want to know 🙏🏼@@TomsCoffeeCorner
The proportional gain is the main gain of the feedback loop. The D gain helps with not overshooting the target (oscillations), and the I helps the P if not being at the target for a long time. This is explained in a video here: th-cam.com/video/qKy98Cbcltw/w-d-xo.html @@roytromb_strength
Thank you @@TomsCoffeeCorner
Hello. The plugs 7 and 8 are not like in the video on my US gaggia classic pro evo. How do I go about it in my case?
Hmm, they might have slightly changed the Evo...I will have to take a look at it in the future.
Can you explain why you changed the P setting from Default?
Increasing the P value just gets the temp to its setpoint quicker. The designer suggested I switch from 40 to 45. Cheers!
@@TomsCoffeeCorner thanks!
Hey, no need to tape the temperature sensor? No leaks?
It's recommended to use thermal paste. 👍
Is it compatible with gaggia classic evo pro
does this PID have a preinfusion setting. im trying to avoid adding a dimmer mod if possible.
It's not really pre-infusion. It just won't reset the timer if you shortly stop and re-start the extraction.
I don’t know what machine can I buy, I saw ascaso dream for aroun 1400 AUD or modify the gaggia
Well, I think the Dream is ugly, so I wouldn't get that one. But that's just me. :)
In all honestly, I would recommend buying a machine though that has a PID built in, because the aesthetics are better (and no machine warranty issues).
What about the Lelit Grace?
Does this tutorial also apply to the 2023 gaggia classic pro evo or just the 2019?
The 2023 shouldn't be any different. Cheers!
Do you still use Dimmer mod with this PID. I thought the PID has pre-infusion. Does Dimmer mod provide separate flow control? Is Dimmer mod necessary if someone already has PID.
The PID does not do pre-infusion. It just won't reset the timer if you cut the pump off, then back on. So yes, the dimmer could still be interesting. But honestly I'm actually satisfied with just using the 9 bar spring most of the time.
@@TomsCoffeeCorner Thanks Tom. Recently I bought PID controller based on your product review and recommendation. The GCP sits in my dad's house and he didn't use it for long time until I installed PID. When I told him about Dimmer mod, he said that the espresso is already good with PID. So I wanted to hear your opinion. I think the Dimmer itself is discontinued from amazon (US link you provided).
Hi! Does it work in 220v machines?
Yes, just be careful of the wiring. I show how to do it on my EU 220V model.
Hey Tom I just finished adding the pid but the light to indicate that the water has reached its temperature on the gaggia seems to flicker and never stops, any ideas on why this is?
Hi Juan. The "flickering" that you're noticing is the PID at work. Now that it is PID controlled, the heating is much more filigrane. When the light goes out, the element is heating.
Before, the heating element would heat until the thermostat was met, and then the light would come on, until the temperature went down below the threshold. But that 2 point system is not as accurate as how your temperature is being controlled now. Hope that helps.
@@TomsCoffeeCorner thank you very much
Why did you refill the boiler at the end? I’ve never seen anyone do that or it even mentioned in the manual.
Well, you have to refill it, otherwise the heating element will be in dry air when you turn the machine on next.
@@TomsCoffeeCorner how do you know if it’s empty or not? Why wouldn’t they include this in the manual?
@@dshafrowith single boiler machines like the Gaggia Classic Pro, you always have to prime the pump after steaming milk. Every single boiler machine requires this. Just a simple flush from the group head for a few seconds will fill it back up. Whole Latte Love and other TH-cam channels have great videos discussing why it's so important for single boiler machines and they show you how to do it. In the Gaggia Classic Pro video section on Whole Latte Love they have a good video on tips and tricks and this is included. The boiler isn't empty, by the way. Only a few inches from the top are exposed but this is enough empty space to impact the life of the heating element if you continue to heat it up the next time with a big gap like that. Priming the pump fills it back up to the top for your next brew.
@@chriskvikstad4980 thanks for the detailed reply! I just don’t get why Gaggia doesn’t mention this in the user manual if it’s so important.
Is this guide applicable to the 2023 Evo pro?
Yes, I installed it on EVO.
Hi Tom, can I ask? I recently bought off Gaggiadirect a Classic from 2019. The brew temperature never gets higher than 77, and I reported this to the Gaggia direct. He replied with "our machines are all set at 70-90 celsius" This is news to me, and my coffee is now awful but was ok the 1st two days after receiving my Gaggia Classic 2019. He wouldn't suggest repairing but instead offered full refund if I sent it back.
Do you happen to have a suggestion? Or should I send it back.
I am really sad today, thanks.
Where are you measuring the brew temp? The espresso temp as it hits the cup is significantly cooler than the temp in the brew group, or in the boiler.
@@TomsCoffeeCorner Hi, hanks for replying. I hit the brew switch and purged into a meal pitcher. The temp always stayed under 80c upon immediately measuring the temp. A Gaggia salesman told me their machines are set at between 70-90 celsius. I did many tests and the water is never ever above 80 celsius.
Does this work for 2015 models or earlier?
Yes, it should. Wiring could change between regions and vintages however, regarding tapping for the power converter. Cheers!
Why’d you choose to do this instead of the Gaggiuino mod?
Well, the Gaggiuino mod looks really cool, but I have not found the time to source the parts and do the install. It seems extremely involved, and I heard putting the SW on the board can require some debugging, too.
are you going to mke more kits available?
The manufacturer should have kits available at the link in the video description. :)
Can it work with 220v machine? Thanks you
Yes, I put mine on a 220V machine. Just have to mind the wire termination, which I highlight in the video.
@@TomsCoffeeCorner thanks you ❤️
How does pre infusion work on this unit?
What happens is actually that the timer will keep timing, if you switch off the brew button during a manual pre-infusion phase. So, it's a manual process, but the timer will keep counting rather than stopping and re-initializing.
Some problems about this machine.
1. The steamer drips all the time, espesially while the espresso shot is taken.
2. 100ml boiler is not enought to steam the milk. While steaming the milk the heat light turns off, meaning, the steam turns to cold. The hot water is allready finishes far before the milk steaming.
You're not wrong. But the steam wand doesn't always drip. It depends on descaling, and maybe some luck. I know that quite a few people have had to replace it though.
As for the milk steaming, just wait 10 seconds, then start steaming. Don't wait for the light. That way it will keep steaming long enough to froth the milk. Cheers!
The steam wand has condensed water inside from your last brew session. It cools and then when you heat the machine back up it drips out. Most people think they have a leak but they actually don't. It's just this residual water dripping out of the wand. Here is the test that the technicians use to determine if your steam valve is actually bad:
Turn on your machine and warm it up. Then flip both the brew and steam buttons on simultaneously but do not open your steam knob. Keep it closed. This forces hot water out of the steam wand but you are keeping it closed for this first step. If nothing comes out of your wand and it's not bubbling, then your valve is fine. Next, open the valve long enough to let a full stream of hot water out and then close it tightly again. If the flow of hot water through the wand completely stops and there's no bubbling, then your valve is fine.
In the Gaggia Classic Pro technical support section on Whole Latte Love they have some videos about how to diagnose steam valve issues and this is the test they do.
You're a bit late to the party installing a PID on a Gaggia, I thought you woudl have done this ages ago. it would be cool to see you do a the Gaggiuino Mod which I might o if I buy a new Gaggia machine, my 2006 classic has been spec out with the Mr Shades, PID, Box and pressure gauge with the dimmer mod so its a failry manual setup.
I waited until I found a PID to my liking. The Shades PID and every other one I know are missing shot timers, and their aesthetics are not pleasing to me.
But Gaggiuino is not a PID and Mr Shades is just a generic chines PID temperature controller.
@@jamesmac6102 That's right. The Shades and most other kits use that generic PID controller, that looks like it's from the 80's. The one I installed has a nice graphical display and shot counter included.
Would this work for a gaggia pro from 2015?
Is that the one with the aluminum boiler, or stainless steel? This mod works on the aluminum boiler equipped models.
I'm new to espresso world, what is pid ?
It stands for Proportional Integral Derivative. It's an algorithm that monitors and controls the temperature of a heating unit during use. It bypasses the basic on/off function of a simple thermostat and uses the heating element in real time to control the temperatures.
Will it work with Gaggia Baby Twin as well?
I am not sure what that boiler looks like. Do you have a picture?
@@TomsCoffeeCorner I will send it in a link. The boiler has 1 thermostat in the left.
is there a way to buy this and it ships from inside EU?
I don't think so.
