I’m back again! This video is great. I’ve just replaced solenoid valve, thermostat switch and boiler gasket. Couldn’t have done it without this video. Just need to fix the leaking steam wand now. So happy it’s working again. Thanks again. Nice coffee tomorrow morning ☕️ 😊
You're welcome and thanks for leaving your comment. If you need to replace the valve/wand we have a video for that. Note that some condensate drip from the wand is normal. You can check for valve leak issue by closing steam valve and turning on brew and steam switch. If no increase in leak with that it's just condensation. Here's video for steam valve leak test: th-cam.com/video/evSHNugOMto/w-d-xo.html

Thanks for this! Took me all the way through to a working machine again. Hope I’ve no more problems, but looks like you’ve got just about everything covered in the channel should something come up.
Great to hear!
Hey Marc and Ted - much appreciate the educational value of your videos. Unfortunately you don't ship to Australia so I cannot repay you by being a paying customer . I had a fuse blow and so ordered a replacement. I haven't yet replaced it as I was concerned it might blow again. I had previously cleaned out solenoid valve following Marc's excellent video but am concerned I had done something wrong when re-assembling that caused the fuse to blow. Are there any checks I can do prior to trying the new fuse ?...Many thanks again Marc for a fantastic TH-cam channel
Hey carlo, Thanks for the kind comment. You might recheck the wiring and make sure everything was connected properly. Sorry it's hard to be more specific. It is a thermal fuse so in most cases it goes due to heat - boiler getting too hot.
Marc
This video was excellent. I replaced the fuse and the two thermostats. I had replaced just the fuse previously but several weeks later the machine stopped working again. This time I decided to replace the fuse and the stats even though when I tested the stats they both seemed to be working. The fuse however was dead. If the fuse dies again I will likely have to find a cause
other than the stats. But I couldn't have done it without Ted's video; at least not with the confidence it provided.
Hi Peter, Thanks for the comment! We have more Gaggia Classic info including wiring diagrams and troubleshooting info available in our Gaggia Classic support wiki here: wiki.wholelattelove.com/Gaggia_Classic
How can you test the 2 thermostats?
Thanks, Whole Lotta Love. This video is brilliant. I replaced two stats and the heat fuse. The butt connectors came with plastic insulation, and I had to make sure not to buy ones that needed a heat gun. I had trouble pushing the clear plastic sleeve back over the thick connectors, bending the heat fuse badly and really straining those connections I'd made. But it's all working. The message is, replace the stats before the heat fuse goes, because it's a tough job making those crimps. There was a warning that the steam stat was finished - the machine thumped and puffed steam like a steam engine because, basically, it was overheating.
Hi Cy, You are welcome, thanks for the comment and sharing your experience. It will help others!
Excellent instruction video. I happen to have a non functioning machine at the moment, with probably a fuse problem. But as stated in de video, when the thermal fuse has to be replaced, there probably is another problem.
Hi Ramsey, Thanks for the comment. Blown thermal fuse can be caused by another problem within the machine like electrical short. Can also be caused by service power surge and simple age without other internal problem.
Whole Latte Love OK thanks! 🙂
Thank you, fuse successfully swapped.
Hi Daryl, That's awesome! Thanks for taking a moment to leave a comment!
Hi guys, very clear video, thankyou!
I replaced the fuse in my Classic 5 days ago and got it working again. It stopped again this morning in the same manner as before - after using the steamer, it would no longer pump. Naturally, I'm dubious of the prospect of just replacing the fuse again and thinking I'll be fine. What are the common causes of the fuse blowing that I can investigate? I should admit I have been a bit lax in descaling my machine recently. Could that be the cause of this re-occurrence?
Hi John, Thanks for the comment and question. The fuse blows when it gets too hot. Most common reason for blowing is leaving the steam switch on for long periods of time. Only turn on steam switch for steaming milk. Once you are done steaming be sure to cool the boiler down. To do that open the steam valve and push the brew and steam switch on. Let the pump run until a solid stream of water comes from the steam wand. Then turn off the brew and steam switches and close the steam valve. If that's not the issue it could be a bad thermostat on the boiler allowing it to get too hot. Here's a video with info on those: th-cam.com/video/3IYXwIUf7Wg/w-d-xo.html
Very unlikely scaling has anything to do the fuse blowing.
Hope that helps!
@@Wholelattelovepage Brilliant, thanks for that info! Yes, I generally always cool the boiler down after using the steamer, also to clear any loose grinds from the shower plate before cleaning up. I don't normally open the steam valve at the same time though (just run the brewer with the steamer switched off), but that would make much more sense and I'll factor it into the routine.
On mature reflection, I think the steam thermostat is likely the problem, since I have also observe a noticeable amount of bubbling from the tank when I switch the steamer on, suggesting there's too much pressure building up. I'll replace the thermostat and thermal fuse and do a descaling cycle on the machine and see what happens.
Nice video , I did scale my machine last week, the problem that just happened my power on light will not come on however the machine will run , any idea please . Thanks
Hi TSBM, Thanks for the comment and question. So machine operates normally except no power light? Maybe just the indicator light is out? If problem is beyond that check our Gaggia Classic support page here for other issues: support.wholelattelove.com/hc/en-us/sections/1500000384362-Gaggia-Classic-Pro

Very good video, thank you. I have a dual boiler Kitchenaid coffee maker (basically a Gaggia) which works perfectly except that neither of the temperature displays work - they never move off zero even though the water from both boilers is hot. If one had gone I'd think it was the gauge itself but both going makes me think its the fuse. This video will help enormously, thanks!
Sounds great!
Perfect, many thanks!!
Thanks for this. I've had the same Gaggia Classic for 15+ years. This is the second time I have had to replace this fuse. I leave it on for a long time (2-3 hours) each morning. Perhaps that is a source of the problem?
Hi Dave, Always nice to hear about longevity of machines like the Gaggia Classic. It may be internal heat causing the fuse to go. Could also be anomalies in power to the machine. With use you describe you are replacing fuse after about 7,000 hours of power on time. When replacing fuse pay attention to location of the fuse with regards to heat sources within the machine.
Marc
Is this Cory barlog
Looks like I’ll have to replace the boiler. Should I also replace thermo fuse while I’m at it?
Hi BD, Only need to replace the fuse if it's bad. But, not a bad idea to have a spare on hand.
I have a question, I bought a Gaggia Classic and made a mistake. I accidentally didn't insert a long hose into the water. I didn't notice that hose was clamped between the walls. And after warming up a little, I turned on the water supply, there was a little water at first and then only steam . After I let it cool down and checked again, it seems to work fine. How much can it harm the machine?
Hi JC, Should not be a problem. Had the machine overheated the thermal fuse would have blown to protect things.
My Gaggia Classic recently developed an issue seemingly out of the blue. Turns on fine, makes the first espresso fine, but trips the kitchen circuit on the second shot. Frother works fine, and does not trip the electrical kitchen circuits. Leaving the power on does not trip the circuit. Only switching on the water pump for espresso. Thoughts? HELP!
Hi Linda, Sounds like either something is wrong with the pump or you have an internal leak under brewing pressure causing water to get on something electrical causing the breaker to trip. Here's a video which can help diagnose leaks on the Gaggia Classic th-cam.com/video/qAc5ZP-Mt4g/w-d-xo.html
I have problem with gaggia pro, indicator lamp for power and steam are on at the same time and no hot water come out from GH and steam wand. Any information about that?
Hi KTH, Not entirely certain what's going on with your machine like if it is heating and the pump is running. Could be the thermal fuse descibed in this video. Here's another video that may be of help on troubleshooting heating issues on the Classic: th-cam.com/video/3IYXwIUf7Wg/w-d-xo.htmlsi=3GbdSj8IQQBBrdsd
Thanks
Hi guys. My GCP is shutting down only when I press Brew Button? What is that? I test this thermal fuse, and it is ok. I also test two thermostat on boiler which are ok. Any idea? Thanks
Hi Joe, Do you mean when you press the brew button you get no flow of water from the group head? Does the machine make hot water if you open the steam valve and press the brew and steam switches together. If both of the above are true it's likely a scale blockage.

I have GAGGIA BABY DOSE, and it Can't turn on, I thougt it because of the fuse, so I wanna replace it..I wanna know the type of fuse should I use, and what causing it? Regards Abba from Indonesia
Thanks for the very informative video.
After reading the comments I decided to replace both thermostats. I have put the Classic back together and turned on and nothing ☹️. I’ve left switch on incase the bulb had blown in on/off switch but it’s not that. Is there anything else I can do before I start looking to replace machine (I really don’t want to replace it. I’ve had it ten years and it’s worked flawlessly until now).
Thanks.
Paul.
Hi Paul, You are welcome for the video. It might be some of the wiring is not quite right. Here's a link to our support wiki for the Classic which has more info and wiring diagrams: wiki.wholelattelove.com/Gaggia_Classic/diagrams_and_manuals
Those could help. If in US you can always give our tech support a call for assistance at 585-924-7170 for help in troubleshooting.
Whole Latte Love thanks for the reply. I tried on last thing and it was the fuse in the wall plug! I’d already put a ‘new’ one in but it must have been a dud. Cheers from UK. 🇬🇧
Great video. I'm getting cold water and no steam on my machine, could it be the fuse? Or is it the elements on the boiler? Ted says that the fuse stops the power completely. So I'm leaning towards replacing the boiler. I've ruled out the thermostats as the steam and the coffee water went at the same time.
Hi TK, Thanks for the comment and question. Here's a link to the troubleshooting section of our support wiki for the Gaggia Classic. It may help. Beyond that, if in US you can call our Tech Support at 585-924-7170 for assistance in troubleshooting.

Hello. How to replace the thermal fuse on a gaggia titanium?. Thank
Hi there , first I would like to thank you for the videos that have helped a lot
I have a problem with my gaggia classic coffee machine , the machine was working normally when I had to change the solenoid valve and after the change the machine turns on but does not heat the boiler , I used a multimeter to test the thermostat and they are passing energy normally and I also tested the thermostatic fuse and it is also passing energy, so I decided to test the resistance that is stuck to the boiler, one of them is passing energy but the other one is not, did it burn the resistance?
could you help me please....thank you very much
Hi JM, If stats and fuse are good and one of the heating elements is shot that could be you problem. Might be time to replace the boiler. If in US/Canada you can contact us for support here: www.wholelattelove.com/pages/contact-us
My Gaggia Classic was working fine but then one morning I turned the power switch on and no light. I am guessing it is the Thermal Fuse. I don't know if the Thermal Fuse died due to some other problem and am wondering if I should also replace the Steam and Brew Thermostats at the same time just in case one of them being bad was the reason the Thermal Fuse died? Prior to this problem I was not having any problems - the brew and steam temperature seemed fine. Should I just replace the Thermal Fuse or also replace both thermostats?
Hi Stephen, I'd visually inspect the fuse and if it's not obvious that's it's blown check with a continuity meter. If blown, I'd start with just replacing the fuse.
I have a used Gaggia Classic that just stopped working. I'm not sure but my power went out because I was always cooking something else but the machine stopped heating up the steam and water. However, the indicator for temperature ready is always on. Do you believe this is a steam and boiler stat problem? The machine still turns on and water comes out. There wasn't any power surge.
Hi Ivan, Here's a link to our troubleshooting section of the gaggia Classic Support Wiki: wiki.wholelattelove.com/Gaggia_Classic/troubleshooting Sounds like it may be a bad thermostat. If in the US give our tech support a call at 585-924-7170 and they can help you diagnose the issue and how to fix.

I have a 6.5 year old Gaggia Color. I just replaced the pump. The new pump seems to run well, but it cuts out after 30-40 seconds (the old pump cut out more often and was somewhat weak). With the new pump, sometimes I can rap on the top and it kicks on again. The wires all seem to fit tightly. If this sounds like a thermal fuse, can I order a replacement through Whole Latte Love?
Hi Kevin, Thanks for the question. Unlikely it’s the thermal fuse unless there’s an iffy connection. Typically when a thermal fuse goes the machine shuts down entirely. If it is the fuse you can order thru Whole Latte Love. But, I’d give our Service Tech’s a call at: 585-924-7170 before ordering. They should be able to help with a better diagnoses of what is going on.
Any idea what material that tubing is made from? I'm fixing a classic for a friend and his doesn't have the rubber tubing over the thermal fuse. Just need to know what material to get at the hardware store?
Hi Andrew, Sorry for the delayed reply - was offline for the weekend. The rubber tube acts as an insulator to prevent shock/contact with other internal components. The tube does not come with the replacement fuse. Are you in the US? If so, give us a call and our techs should be able to find you a tube. www.wholelattelove.com/contact-us
184 C but the amper? 10A? Or more?
Here is the part: www.wholelattelove.com/products/thermal-fuse-184c-limit
How much ampere is there?
What size/type/brand butt connectors did you use? I'm guessing 22-18 gauge maybe? I see some connectors have seams and some don't. Some are tin plated copper, some are nickel plated steel. Help! I have a new thermal fuse on order and want to have the right butt connectors when it gets here.
Hi Steven, thanks for the question. Either should work. Personally I'd prefer the copper.
Hi! I have the Gaggia classic pro and the middle light doesn't go on, is it because of the fuse? Thanks!
Hi IS, Thanks for the question. If thermal fuse is blown that generally cuts power to the entire machine. There'd be no lights or heating at all.
Yeah, i bought the Gaggia classic pro from you guys about 6 months ago. We were doing a shot and the pump cut off and the light for the pump went off but the power switch light stayed on. You can cut the power switch on and get power to that switch but the unit does not heat up nor does the pump work at all when you cut the switch on. I'm thinking the classic pro is wired differently and that it's the thermal fuse blown. However I'm not sure because on the old classic, you guys say it kills all power. Could it be different wiring between the two and its still the fuse blown?
Hi Jason, Sorry you are having an issue. Hopefully you've contacted our tech support specialist by phone. If not they can quickly take you through diagnosing the issue and solving it. Contact info for tech support here: www.wholelattelove.com/pages/contact-us
@@Wholelattelovepage Well , it was the Thermal Fuse , I replaced it and its working great , awesome work with videos and thanks =)
Hey guys, maybe you can help with this: I just got a new Gaggia delivered, thing is, as soon as I pluggged it to the wall a power surge happened (this without turning the machine on). This caused a small burned smell and burned male pin. What would be the advice in this situation?
Thank you in advance
Hi AM, Have you tried plugging the machine in again? Was the power surge caused by the source power? I'd try the machine in a different outlet.
@@Wholelattelovepage Thank you for the fast response, I tried a different outlet and the same happened. This outlets are working with other appliances.
The power surge is caused in the moment that there is contact between the Gaggia plug cord and outlet.
so if this blows, the machine appears dead? The reason I ask is that I have an overheating issue - leave the machine on for about 20 mins and it cuts off, no pump, just a click sound. Needs a long cool off to fix. I've changed both thermostats but no improvement. :-(
Hi paul, Thanks for the question. Excuse my delayed response - been on vacation and offline for a week. Yes, if that fuse goes then the machine would have no power. Here's a link to the troubleshooting section of our support wiki for the Gaggia Classic: wiki.wholelattelove.com/Gaggia_Classic/troubleshooting There are wiring diagrams etc available at that link as well. Please be advised this guide is for the North American version of the Classic and may not reflect certain models sold in EU and elsewhere.

Hi. Few questions. Changed my classics fuse and I cuted the rubbing tubing . Wrapped the fuse in electrical black tape and put it back on the boiler with the clip. Now my gaggia is giving me shocks.
Is it because the tape is not insulating enough? I need the silicon tube? Why the fuse goes on the boiler? Could it be floating on the Air? Thanks!
Edit: what's rubber tubing part name or can I get it in home Depot?
Why would the boiler overheat to cause the fuse to blow?
Hi David, Could overheat if there was a problem with the thermostat on the boiler. Also as the result of misuse as in leaving the steam switch on for extended periods and failing to cool down/refill the boiler after steaming.
My classic doesn't turn on. Pretty sure is the fuse, but I wonder why the fuse went off... What's the common issue?
Hi AC, Fuse can go with a power surge, electrical short within the machine or in rare cases with age.
@@Wholelattelovepage I see corrosion on top of my boiler, right on the steam wand connects.. What do u think?
Do you know what happened my Gagiga classic water is not hot enough
Hi Chen, Could be a number of issues. Here's a link to our support wiki for the Gaggia Classic. Check the troubleshooting section there: wiki.wholelattelove.com/Gaggia_Classic
What type of butt connectors do you need?
Hi Kaleb, If you purchase the thermal fuse here it includes the butt connectors: www.wholelattelove.com/products/thermal-fuse-184c-limit
Unfortunately, I don't know the specific size of the connector. If you already have a fuse and no connectors you'd want one that's a good fit with fuse and source wires.
