This is so much engineering work. These machines are much more complicated than I would of originally expected. The wide range of components, sensors ,and integrated systems is cool to learn.
Super automatic espresso machines make this look super simple lol. They have built in coffee bean grinders, an automatic coffee tamper and ejection mechanism and automatically grind the beans, put the ground beans in the filter, tamp them under high pressure, brew the espresso under very high water pressure (it has special high pressure tubing and connections) and eject the used coffee grounds into a waste coffee bin at the press of a button. The machine costs a lot more but you then get even better coffee for pennies per cup compared to k-cup/pod machines so they pay for themselves.
The flap stops the pressure to the needles if you should open the lid while brewing. This prevents the needles from spraying hot water and coffee on you when you open the lid.
Our flap became removed during a cleaning. Afterwards, the machine produces only clear hot water, no coffee. Any suggestions on reinstalling the flap? We still have it, intact. Keurig support tried to sell me a new machine.
That thermo-sensor is actually resettable. There is a small hole in the center of it and you can reset the switch with something like a paper clip. Had an issue with mine after a failed descaling process which seems to be a common issue with these units. The entire unit would not power up due to that thermo-switch being tripped off. Reset it with a paper clip in that hole and the unit came back to life.
OMG! THANK YOU! THANK YOU! THANK YOU! I've had 3 multi-stream brewers mysteriously die on me. Keurig has always been great about quickly replacing the machines under warranty, but when my latest unit died this morning, I wanted to see if I could save it. The video helped me with disassembly and diagnosing the problem, but your comment allowed me to reset the machine and had be back in business.
A very professional presentation, simple and straight forward, easy to understand!! Thank you so much. I just bought a new Supreme Plus from Costco. Now, after watching your explanation with all the internal parts visible I feel so much better using this machine. It feels like the user, myself, now is closely connected to my coffee maker. The confidence builds up and the joy of owing this machine escalates. Buddy, a job well done!!!!!!!!!!!! This is a delightful video to watch.
@@JustADad hello, I used to repair IBM mainframe and has been heading the central electronic maintenance team for the whole university, for years. Hehe, I give you a thumbs up with all my sincere feeling. 😀😀😀😀😀, Toronto.
As someone who loves teardowns, and has the newer K-Supreme Smart I was always curious how it worked compared to the older models. I appreciate the through breakdown.
Our Keurig suddenly would not turn on and I figured there must be a reset switch, etc. I took the coffee maker apart as far as I could but could not get the outer cover off. I put the coffee maker back together and decided to see what I could find on the web and low and behold this video that demonstrated the whole procedure for correcting the issue and take the main cover off. Thank you so much, I pushed the reset and now I am enjoying another cup of coffee and relaxing after another good morning at the office(garage/repair shed).
Thank you the demo on descaling. I never took the time to read my instructions as to what that one meant, but now I know and know my coffee taste freshly brewed instead of tasting like water. Demos are very helpful. I definitely prefer the vinegar for cleaning as it’s a household product we use for various purposes. It’s definitely good for cleaning multiple things. Thanks again
I really appreciate everything that's packed inside one of these. Just got new K Supreme Smart and it's a little intimidating. So far I've done a Cleansing Brew and made one cup of Columbian Roast using an off-brand K-style cup. First time I closed the lid the machine didn't 'see' the cup. I raised the lid and re-seated it and suddenly we were cleared for 'ignition'. The coffee tastes better with the multi-stream tech that this K Supreme Smart employs.
Perfect video for the thermostat reset. We came back to our cabin after the long winter and our machine was not powering on. I followed your instructions step by step, albeit a bit skeptic. It amazingly worked the first time Small heroes! Thanks!
Well-this helped to understand why our Keurig stunk so bad. Our K Supreme smelled and the coffee tasted like mildew. I descaled whenever it said to, and I constantly cleaned the inside of the reservoir. Ends up, the mold smell was in the rubber and spring on the underside of the reservoir where the it connects to the water flow. The area that connected the reservoir to the machine was always wet and it smelled, as well...the little tubes that go to the water level sensor could were part of the problem. The smell was embedded in the areas you couldn't access.
Thank you! I thought my Keurig was toast, but it happened so quick I suspected a fuse or something. After watching your video's found & corrected the problem. Thanks again
Thanks for sharing and posting! Just upgraded to a K-Supreme Plus from the original Keurig and wondered how the water in the supreme plus heated up so much quicker without having to wait before it dispenses. So many neat innovations done throughout the generations of the product.
Thank you! It was great seeing the two pumps and how they work together. It appears that the pneumatic purge pump comes on as soon as the fluid pump turns off. One of the pressure switches must tell the machine when the water has been purged from the lines to end the cycle.
I disassembled a tank style Keurig, a project in itself, all kinds of pumps, sensors, tubes, compressor, voltage regulator. Now I want to design a project to control some of them with a Arduino micro controller, write some code, and see what I can make. Thanks for the video.
Excellent video tutorial, low flow is my problem. Volume chosen will always be -2 oz ! Clog other than needles, black 5 outlet is my quests. Thanks for you , video quality is great pinch and zoom 👍🏆
I was pleasantly surprised to find this video. I came looking for detail on the needle, curious about how many holes it has (more than one?), at what level into the cup it extends, and how the exit hole is made. It's kind of amazing that it could utilize all the coffee in the cup just by shooting water in with one hole. Seems like it would at least have to rotate, but that would be too complicated. More likely is that it wastes a lot of the coffee, but in the end you always get a nice cup of Jo, so who cares.
Thanks! Your video really HELPED! Getting the case off WAS a struggle (as you promised!) Once inside, I found the thermostat cutoff/reset and reset it. It still had a problem with the unit shutting down. As an experiment, I disconnected the hose nearest the right cabinet side panel. The unit fired up fine over and over to do the descaling but the "Add Water" light did not come on. The water got TOO low, the safety thermostat shut OFF and there it was......dead again. Reconnecting the hose did NOT make things normal. Soooooo, to keep using my machine, it is CONSTANTLY in "Descale" mode after I press 8 and 12 oz buttons for 3 seconds. I make SURE that the water tank has lots of water. I fill my reuseable K-pod, put my mug, press K and get a 12 oz. cup of nice strong boiling hot coffee. Between uses I disconnect the AC to the unit to save power and also, so that it can't overheat. QUESTION: Is the hose I disconnected to do with the air pump and the "ADD WATER" function? Again, THANKS A MILLION! Old Man Rob, in Canada, EH?

WELL DONE!! Your style of explanation and clear video are a welcomed relief. So many other TH-cam presenters make too many assumptions when trying to explain things. I wish they were all as methodical and detailed as you.🫡👐
I would think it is like a relief valve incase the handle is opened while the system is still under pressure. Would blow hot water and steam down vs out the needles at the user.
The connector on the side of the water pump lets the computer verify the pump is rotating and not jammed, and the computer also likly uses it to measure the quanity of water delivered,.. I think it uses reads magnetic pulses from a revolving internal part with a hall effect sensor and the computer can read these pulses to determan the pump is running before it turns on the heater as a safety confirm so the heater is not switched on without water flow ..
I'm glad I came across your video on the Keurig K Supreme. After watching your video and putting my Supreme back together and having it work, I do have a couple comments. First of all, your explanation of how the plumbing of the Supreme works had some incorrect info and mistakes in your video. The first issue I noticed was you were holding the water level device upside down. That device has a thermocouple sensor in it along with the probes to indicate water level is low. The second issue that would have been very useful would be to remove the electrical panel covering all that plumbing that you were trying to explain to show the routing of all those hoses. Your explanation of the water flow would have been much easier and would be of great benefit to anyone who removes those hoses and forgets how they go back together. Fortunately for me, with your general explanation, I was able to replace all my hoses on my machine and the Keurig worked when I had it completely assembled. Thank you for you videos. Please produce a more detailed water flow explanation with showing all tubing connections.
Well aren’t you smart 👍🙌🏻! That was really neat seeing how it works with the cover off. Thank you for sharing that with us and explaining everything to us/me. That was fascinating.
that rubber cover beneath the needles, is for pressure release in case you open the keurig while operating, so it doesnt squirt you in the face/body with steaming hot water.
If you are here for as dead Keurig, find the thermal breaker about the diameter of a dime with a hole in the center of it, two wires coming from it. It's likely stuck open, push a toothpick or something into the hole to reset. If you know how to use a multimeter check to make sure it's closed (or was open). THIS is a very common mode of failure on these units. You likely have the problem if goes dead, no power. Easy fix!
If this was a TV or video player it'd probably last awhile but when you add heat & moisture I'd be surprised if these last 18 months with average use. Just bought one and wished I hadn't seen this...but thank you.
On the side of the water pump is actually a IR sensor, I'm guessing its used to measure water flow. I had an issue with a keurig k latte single serve where the lights where all on and pressing the power button would cause the air pump to run. After trying everything, I injected water using a syringe through the water pump into the system and that caused the machine to reset and start working again. The board does say IR sensor where that pcb on the side of the water pump plugs in. It seams the system would only start the pump after seeing water run through it but it would only push water through it if the pump was working, hence the need for the syringe to jump start the whole thing.
@@JustADad I should have videoed my adventure, but I only through about it after I had watched all your videos and resolved my issue. BTW your anatomy of how these machines work, helped tremendously, I would not have been able to get anywhere without your videos. THANK YOU!!!
Thanks for the vid. Whanted to see if i could micro build it myself using a used one. yes definitely can micro build something with the parts. Just the heating element needs to be bought. $7 bucks in amazon. This explained enough safety focus for my build. Again thanks for the video.
Slight difference between this and the supreme plus on the mother board. instead of a pressure probe connector on the mother board, there is a more robust bus box labelled "FPN-07PG" made in Japan. The issue I keep running into is the thermal sensor keeps needing to be depressed, and I'm wondering if it's connection to the heating coil has become degraded over time. The symptom each time during brew is the shutoff after the third dot on the HUD. I have probably reset that thermal sensor about five separate times now. I get it to work for about a month and then it seizes again. Real pain.
@@JustADad yes and no. Unfortunately, the actual descale mode overheats the thermal sensor. I ran full descale mode and within two brews the following day, the auto-shutoff triggered on the third dot of the brew cycle. Ultimately, you end up with the descale HUD message never going away, but it's fine. I just manually descale every few months. I keep temp and strength settings minimal and will run about two 12oz "brews" of 1:1 water-white vinegar solution. After, I just unplug and leave alone, run clean water the next day to flush the vinegar and rinse. This pretty much prevents overheat.
I have power but it appears the control is stuck on the strength and temp adjustment and it clear. Also, I can get it to descale mode with the flashing K but it won't pump the solution. I've cleaned the needles and tried the baster without success. Any suggestions?
Do you have a video on how to remove the top door? The micro switch is giving me grief, not detecting the door opening or closing, on my Supreme and I would like to shoot some contact cleaner in it or simply replace it.
The one I have is a K85 with the milk frothier attachment. It only uses one air pump and two outlet lines, one to the head needle and the other to the bottom of the k cup. Not sure what the bottom line does for the bottom of the k-cup? That bottom of the K cup has a needle as well to puncture the bottom. I think two hot water entry system, one from the top and the other to the bottom.
I had the issue where I was able to reset the heating element but it was not pumping water out. I tried different troubleshooting methods and finally narrowed it down to the pump, or the circuit board itself. Luckily I had a 12 volt battery. I connected some wires directly to the connector for the pump and the pump worked fine. I figured that this machine was toast and it was the circuit board that was bad. I put everything back together and decided to try and run it again. To my surprise, the machine started working. It’s almost like the pump was stuck and needed extra power in order for it to get going again.
Can you look at your functioning Supreme units and tell me if the small diameter tubing leading to the pressure sensor on the circuit board is full of water or full of air? I had other repairs to make on my unit and that tubing was removed and then reinstalled. I am wondering if it is supposed to be full of water to carry pressure to the sensor on the circuit board to tell it to keep the brew cycle going. My brew cycles are stopping after about 5 seconds. Thanks.
This is a great video! I'm thinking about taking my K-Slim apart to see if I can figure out why it stops dispensing after just a few seconds! After I bought it, I used it for 2 months without issue... but I live outside the US and brought it back with me in my suitcase, and now I'm having this issue. Descaling did not fix it. Resetting did not fix it. I think it might be a problem with a sensor or pump. What should I be looking for?
Very cool. My water level sensor does not work. Not sure why since it’s a simple sensor that seems to use 2 wires to complete the circuit when under water. I wonder what it looks like inside the plastic case?
Very nice explanation, I repaired mine with the reset but also clogged tube, noit water got to the heater so would reset. The pump was not priming bcus water was below half. So tested pump and worked. Removed tubes blow in air. Closed tube filled to top, and runned. Decaled afterwards. Again very good instruction on the path of the water. Did you catch that stm32f ??
i have a $10 simple thing from walmart that does both grounds and k-cups for single serve. will never buy a keurig and no need for a mr coffee either, it simply works
Excellent work. So I guess the electronics control the number of Ounces that get dispensed? Often, when I push the 10oz. button I'll get either 8oz.10oz or even 12oz.
In the video you mention that the water pump is quiet. Our Cuissenart has always been loud with a muffled growling sound. It seems to perform well. Any hints or tips?
hmm, funny since that’s what also failed on the one I took apart last year. The problem is the water pump was fine and it seems most fail during descaling. Finding that exact temp and spec replacement part is almost impossible. So just match it as close as possible with a slightly higher temp one.
@4:29 The thermostat is "non-resettable." I have heard that a paper clip pushed into the hole in the center of the thermostat will reset it. I've never tried it, so I don't know.
I bought the K supreme from BJ's club abought a year and a half ago and I bought another for a friend. Both were duds. I only use mine for iced tea and the water stream has always been very slow and less than what was selected. The descaler light comes on all the time. Descaling seems to have no effect. I can tell there is a blockage. I tried the paper clip on the needles, and they were not clogged. So, thanks to your video I took the cover off and started looking for the problem. Long story short, the clog is in the check valve which is built into the multi stream head which you cannot take apart to clean. I should be able to blow air though it and it was clogged up tight. I am soaking it in vinegar hoping it clears up. There was also a clear slime in the tube right at the check value. I think it's a poor design and they should have a recall on the unit.
100% support your point of view! I have the same issue as that of yours. The multi stream head is a literally a defective design! After treatment by vinegar, did you revive it ? what is current status ?
@@悟入木三分 I broke down and bought another unit direct from Keurig, same model, and this one works great. Comparing the new one with the old one I believe the first one had a defective pump.
Does the water actually come out of all 5 holes? 🤔 Or does it only come out of the classic center stream main one, and then spread across the top of a Kcup and possibly drip into the other 4 holes? I’m curious because the center spike is the only one that looks hollow, and like it can actually deliver water. The other 4 just look like solid hole punchers.
The bottoms of them are solid but just above a little bit (where the rubber washer type part is) they have holes in the sides of them that lets the water flow.
Hey dad, do you know if the k-duo single and carafe brewer has a one way check valve in it? Mine is making pumping noise but not water coming out of the kcup side. I'm going to try all the fixes but that's the one I think is the issue and there's not much to go on. Thanks!😃
Yes, I made a video how to take apart, they are really hard to take apart, I have had some viewers use a air hose and blow air in the line to unclog the check valve. th-cam.com/video/ZI6LhGropQI/w-d-xo.html th-cam.com/video/oo18XZQpXXY/w-d-xo.html th-cam.com/video/w1prLPfX7xg/w-d-xo.html
Extremely helpful and the comments assisted in the over temp reset. My unit was unused for months and after a descale I realized I was only pumping a ful cup when the water tank was full to the top 2/3erds. Any ideas? Maybe still need to descale? Also now my display goes dark after 1 second. I’m thinking the ribbon cable is loose or steamed/corroded after many short cups of hot water after descaling. Any ideas on how to check/clean the ribbon cable in the lid? Thanks in advance….
@@paigemitchell8131 I would call Keurig customer care at 866-901-2739. This could be a known issue Keurig has with this model of Keurig. I have had other viewers with the same thing. When they called Keurig some of them said Keurig knew about this issue and sent them a new Keurig. They have great customer service. I think you will need proof of Purchase. So sorry this happened. I hate it when someone follows my directions and then it breaks their machine. I am so sorry.
@@cherylcalifornia125 yes you should descale your machine. I like the Keurig Solution but it is more expensive and sometimes hard to find. I use the Keurig solution.
Just to add, the thermostat or thingy IS RESSETABLE. Just insert tooth pick or paper clip in middle where you see that white circle with power off, then power on, done.
Hey, thanks for going, how does it sense water level?... lol, been wondering myself since using the things. I got a dead one out back that I haven't destroyed, I think I will check it out lol! Thanks for doing the teardown, It"s kind of a 'Modern Marel'!
It's now Jan 2024 and I've had my K Supreme for a year. Several months ago it stopped producing the volume assigned to each button, IE, 12oz➡️10oz; 10oz➡️8oz, etc. The deficient value is 2 oz at each setting. All needles have been cleaned multiple times; descaling performed multiple times; factory "reset" performed, deficient volume remains. Logic board vs bad pump vs ?? I found this video interesting as I thought there might be a needle assembly check valve as depicted for other units. Your disassembly of the needle assembly did not show such a valve. Is the line to the pressure transducer supposed to contain water as in your video or be open to atmospheric pressure?
Is your unit running longer for increasing cup size selection or does it shut down after the same amount of time regardless of cup size? If it shuts down after the same amount of time, I suspect a water flow sensor's signal is not being detected. In this case the circuit stops the brew cycle after the same amount of time. I have a K-910 (no digital display and has a pressure sensor mounted directly on the circuit board). My unit is short cycling after I tried to remove visible scale from the small hose leading to the pressure sensor.
I looked online and could not find a replacement Thermostat. The wires are soldered on it. Which you could unsolder and solder them on the new one. When this Open up from High temp it does not close. I think its a one time use. it right on the heating element so if it get too hot the Thermostat open up. You could replace it if you can find one.
Take the pump apart and you'll see it's has three chambers, or valves. What is curious is there is a cam on the shaft that does not ride or touch anyting, (so it's not a cam) but passes infront of somthing on the circuit board on the side of the pump. How does the different cup sizes? is this the piece that detmindes that.
That rotating "cam" appears to be a magnet that creates magnetic pulses as it rotates (a Hall Effect circuit). Those pulses are counted by the circuit board. Each pulse represents a very small volume of water that has passed through the pump. Each cup size has an associated number of pulses that must be counted when the pump is running. After the specified number of pulses is reached the water pump is turned off and the air pump turns on for a defined period of time to purge the water line and the K-cup of water.
We descale and now it won’t work - unplug let it cool down the right side of machine seems real hot ( wonder why they didn’t put a vent ) . Hope it works this is our second machine from Costco and if the thermostat is broke this one will go back to Costco
My Keurig IA pumping too much water(ie.. 12 ounce overfill my 12 ounce cup, 10 ounce fills my 12 ounce cup). Have found WHAT controls the amount of water dispensed? cool video, thx
This is so much engineering work. These machines are much more complicated than I would of originally expected. The wide range of components, sensors ,and integrated systems is cool to learn.
Super automatic espresso machines make this look super simple lol. They have built in coffee bean grinders, an automatic coffee tamper and ejection mechanism and automatically grind the beans, put the ground beans in the filter, tamp them under high pressure, brew the espresso under very high water pressure (it has special high pressure tubing and connections) and eject the used coffee grounds into a waste coffee bin at the press of a button. The machine costs a lot more but you then get even better coffee for pennies per cup compared to k-cup/pod machines so they pay for themselves.
Which eventually and unfortunately makes it more prone to failure.
The flap stops the pressure to the needles if you should open the lid while brewing. This prevents the needles from spraying hot water and coffee on you when you open the lid.
Awesome!! thanks so much!!
I was guessing the flap allows any remaining water to drain out of the needle area when you open the lid, to prevent mold growth and clogging.
Our flap became removed during a cleaning. Afterwards, the machine produces only clear hot water, no coffee. Any suggestions on reinstalling the flap? We still have it, intact. Keurig support tried to sell me a new machine.
Thanks for the info ! I was thinking it was a steam release vent.
@@Thymediadude thats my problem too - did you ever figure it out???

Much better than drilling holes in the side hoping to tag the thermal reset. Thanks
WELL DONE!! Your style of explanation and clear video are a welcomed relief. So many other TH-cam presenters make too many assumptions when trying to explain things. I wish they were all as methodical and detailed as you.🫡👐
Thanks for showing what the Keurig is like inside. great job / Happy 2024 🎉 😅☕️👍
Thank you, it fixed my keurig..reset hole did the job.
Great to hear!
That little rubber flap has to have a purpose. Now you have me thinking. Great video very interesting
Thanks 👍
I would think it is like a relief valve incase the handle is opened while the system is still under pressure. Would blow hot water and steam down vs out the needles at the user.
Great instructions just repaired mine thanks for the info
The connector on the side of the water pump lets the computer verify the pump is rotating and not jammed, and the computer also likly uses it to measure the quanity of water delivered,.. I think it uses reads magnetic pulses from a revolving internal part with a hall effect sensor and the computer can read these pulses to determan the pump is running before it turns on the heater as a safety confirm so the heater is not switched on without water flow ..
I'm glad I came across your video on the Keurig K Supreme.
After watching your video and putting my Supreme back together and having it work, I do have a couple comments.
First of all, your explanation of how the plumbing of the Supreme works had some incorrect info and mistakes in your video.
The first issue I noticed was you were holding the water level device upside down. That device has a thermocouple sensor in it along with the probes to indicate water level is low.
The second issue that would have been very useful would be to remove the electrical panel covering all that plumbing that you were trying to explain to show the routing of all those hoses. Your explanation of the water flow would have been much easier and would be of great benefit to anyone who removes those hoses and forgets how they go back together.
Fortunately for me, with your general explanation, I was able to replace all my hoses on my machine and the Keurig worked when I had it completely assembled. Thank you for you videos.
Please produce a more detailed water flow explanation with showing all tubing connections.
Great, straight forward explanation and breakdown. Thanks!
This video is Dad approved 👍. I will be descaling mine in the future so I am interested to see what happens. Stay tuned.
Thanks
Thank you ... Finally I understand how it works and how to troubleshoot mine
Glad it helped
This video was perfect for me. Thanks my dude for uploading this. 👍🏻👍🏻
Glad I could help
Very thorough explanation! Really interesting!
Glad it was helpful!
Great info, thanks, saved me from cutting one apart.
You're welcome!
Well aren’t you smart 👍🙌🏻! That was really neat seeing how it works with the cover off. Thank you for sharing that with us and explaining everything to us/me. That was fascinating.
Thanks for Watching and your kind words!!!!
that rubber cover beneath the needles, is for pressure release in case you open the keurig while operating, so it doesnt squirt you in the face/body with steaming hot water.
If you are here for as dead Keurig, find the thermal breaker about the diameter of a dime with a hole in the center of it, two wires coming from it. It's likely stuck open, push a toothpick or something into the hole to reset. If you know how to use a multimeter check to make sure it's closed (or was open). THIS is a very common mode of failure on these units. You likely have the problem if goes dead, no power. Easy fix!
If this was a TV or video player it'd probably last awhile but when you add heat & moisture I'd be surprised if these last 18 months with average use. Just bought one and wished I hadn't seen this...but thank you.
On the side of the water pump is actually a IR sensor, I'm guessing its used to measure water flow. I had an issue with a keurig k latte single serve where the lights where all on and pressing the power button would cause the air pump to run. After trying everything, I injected water using a syringe through the water pump into the system and that caused the machine to reset and start working again. The board does say IR sensor where that pcb on the side of the water pump plugs in. It seams the system would only start the pump after seeing water run through it but it would only push water through it if the pump was working, hence the need for the syringe to jump start the whole thing.
Wow that is some good troubleshooting!! thanks for sharing, I learned something useful today!!!
@@JustADad I should have videoed my adventure, but I only through about it after I had watched all your videos and resolved my issue. BTW your anatomy of how these machines work, helped tremendously, I would not have been able to get anywhere without your videos. THANK YOU!!!
I have to say.. very well done!
Was looking for an internals video on Keurig with Latte/Cappacino. Thanks!
Thanks for the vid. Whanted to see if i could micro build it myself using a used one. yes definitely can micro build something with the parts. Just the heating element needs to be bought. $7 bucks in amazon. This explained enough safety focus for my build. Again thanks for the video.
Glad I could help
Great video brother
Thanks so much!
Interesting to see that they have changed the heating element. In older machines, they had tanks. Which one do you think is long-lasting?
Slight difference between this and the supreme plus on the mother board. instead of a pressure probe connector on the mother board, there is a more robust bus box labelled "FPN-07PG" made in Japan.
The issue I keep running into is the thermal sensor keeps needing to be depressed, and I'm wondering if it's connection to the heating coil has become degraded over time. The symptom each time during brew is the shutoff after the third dot on the HUD. I have probably reset that thermal sensor about five separate times now. I get it to work for about a month and then it seizes again. Real pain.
wow thanks for some really detailed information. have you been keeping up on the descaling?
@@JustADad yes and no. Unfortunately, the actual descale mode overheats the thermal sensor. I ran full descale mode and within two brews the following day, the auto-shutoff triggered on the third dot of the brew cycle.
Ultimately, you end up with the descale HUD message never going away, but it's fine. I just manually descale every few months. I keep temp and strength settings minimal and will run about two 12oz "brews" of 1:1 water-white vinegar solution. After, I just unplug and leave alone, run clean water the next day to flush the vinegar and rinse. This pretty much prevents overheat.
i have a different brand- used it for years, never descaled. still use it.
Great walk through!
I have power but it appears the control is stuck on the strength and temp adjustment and it clear. Also, I can get it to descale mode with the flashing K but it won't pump the solution. I've cleaned the needles and tried the baster without success. Any suggestions?
worked great , thanks a bit of a chore getting the cover off haha
Glad it helped
Do you have a video on how to remove the top door? The micro switch is giving me grief, not detecting the door opening or closing, on my Supreme and I would like to shoot some contact cleaner in it or simply replace it.
Keurig should make a transparent version for us Tech nerds
Awesome video!!!! 👍👍👍
Thank you! 👍
Great information
Glad it was helpful!
super helpful! thanks!
The one I have is a K85 with the milk frothier attachment. It only uses one air pump and two outlet lines, one to the head needle and the other to the bottom of the k cup. Not sure what the bottom line does for the bottom of the k-cup? That bottom of the K cup has a needle as well to puncture the bottom. I think two hot water entry system, one from the top and the other to the bottom.
I had the issue where I was able to reset the heating element but it was not pumping water out. I tried different troubleshooting methods and finally narrowed it down to the pump, or the circuit board itself. Luckily I had a 12 volt battery. I connected some wires directly to the connector for the pump and the pump worked fine. I figured that this machine was toast and it was the circuit board that was bad. I put everything back together and decided to try and run it again. To my surprise, the machine started working. It’s almost like the pump was stuck and needed extra power in order for it to get going again.
Can you look at your functioning Supreme units and tell me if the small diameter tubing leading to the pressure sensor on the circuit board is full of water or full of air?
I had other repairs to make on my unit and that tubing was removed and then reinstalled. I am wondering if it is supposed to be full of water to carry pressure to the sensor on the circuit board to tell it to keep the brew cycle going. My brew cycles are stopping after about 5 seconds.
Thanks.
This is a great video! I'm thinking about taking my K-Slim apart to see if I can figure out why it stops dispensing after just a few seconds! After I bought it, I used it for 2 months without issue... but I live outside the US and brought it back with me in my suitcase, and now I'm having this issue. Descaling did not fix it. Resetting did not fix it. I think it might be a problem with a sensor or pump. What should I be looking for?
What does the air pump actually do? increase flow pressure? clear lines after cycle? Is it controlled by micro to maintain a brew chamber pressure?
That flap looks like a pressure release valve so you don't get sprayed if you open it under pressure. Thanks for the in depth vid!
Very cool. My water level sensor does not work. Not sure why since it’s a simple sensor that seems to use 2 wires to complete the circuit when under water. I wonder what it looks like inside the plastic case?
Very nice explanation, I repaired mine with the reset but also clogged tube, noit water got to the heater so would reset. The pump was not priming bcus water was below half. So tested pump and worked. Removed tubes blow in air. Closed tube filled to top, and runned. Decaled afterwards. Again very good instruction on the path of the water. Did you catch that stm32f ??
great video! did you ever try to blow from water inlet of manifold (needles) ? could you blow through it? Thanks
that would work I think
It is resettable. There is a pin hole on the back of it. Just reset it by using a paper clip.
Yes th-cam.com/video/IdE_4NIQEro/w-d-xo.html
i have a $10 simple thing from walmart that does both grounds and k-cups for single serve. will never buy a keurig and no need for a mr coffee either, it simply works
Excellent work. So I guess the electronics control the number of Ounces that get dispensed? Often, when I push the 10oz. button I'll get either 8oz.10oz or even 12oz.
In the video you mention that the water pump is quiet. Our Cuissenart has always been loud with a muffled growling sound. It seems to perform well. Any hints or tips?
If you connected the two continuity wires then you would be able to use all the water in the tank, correct?
hmm, funny since that’s what also failed on the one I took apart last year. The problem is the water pump was fine and it seems most fail during descaling. Finding that exact temp and spec replacement part is almost impossible. So just match it as close as possible with a slightly higher temp one.
This is so cool!!
Thanks for watching!
@4:29 The thermostat is "non-resettable." I have heard that a paper clip pushed into the hole in the center of the thermostat will reset it. I've never tried it, so I don't know.
Thanks for showing.
I bought the K supreme from BJ's club abought a year and a half ago and I bought another for a friend. Both were duds. I only use mine for iced tea and the water stream has always been very slow and less than what was selected. The descaler light comes on all the time. Descaling seems to have no effect. I can tell there is a blockage. I tried the paper clip on the needles, and they were not clogged. So, thanks to your video I took the cover off and started looking for the problem. Long story short, the clog is in the check valve which is built into the multi stream head which you cannot take apart to clean. I should be able to blow air though it and it was clogged up tight. I am soaking it in vinegar hoping it clears up. There was also a clear slime in the tube right at the check value. I think it's a poor design and they should have a recall on the unit.
100% support your point of view! I have the same issue as that of yours. The multi stream head is a literally a defective design! After treatment by vinegar, did you revive it ? what is current status ?
@@悟入木三分 I broke down and bought another unit direct from Keurig, same model, and this one works great. Comparing the new one with the old one I believe the first one had a defective pump.
Does the water actually come out of all 5 holes? 🤔 Or does it only come out of the classic center stream main one, and then spread across the top of a Kcup and possibly drip into the other 4 holes? I’m curious because the center spike is the only one that looks hollow, and like it can actually deliver water. The other 4 just look like solid hole punchers.
The bottoms of them are solid but just above a little bit (where the rubber washer type part is) they have holes in the sides of them that lets the water flow.
Hey dad, do you know if the k-duo single and carafe brewer has a one way check valve in it? Mine is making pumping noise but not water coming out of the kcup side. I'm going to try all the fixes but that's the one I think is the issue and there's not much to go on. Thanks!😃
Yes, I made a video how to take apart, they are really hard to take apart, I have had some viewers use a air hose and blow air in the line to unclog the check valve. th-cam.com/video/ZI6LhGropQI/w-d-xo.html

It would be cool to see if you could get a clear case made for a Keurig machine, like a custom plexiglass case
That would be very cool!!!
Extremely helpful and the comments assisted in the over temp reset. My unit was unused for months and after a descale I realized I was only pumping a ful cup when the water tank was full to the top 2/3erds. Any ideas? Maybe still need to descale? Also now my display goes dark after 1 second. I’m thinking the ribbon cable is loose or steamed/corroded after many short cups of hot water after descaling. Any ideas on how to check/clean the ribbon cable in the lid?
Thanks in advance….
The over temperature sensor stays set/made. So that is not my problem.
Maybe a clogged in line. blow some air through some of the pipes.
What happens if you accidentally push the keurig to run water out the tank being in? Did I ruin it? I have that same model. Thank you
Yes it could stop working after this. does your still power on?
I descaled mine and now it all of a sudden won’t power on. Follow directions from the manufactured website. Not sure what happened.
@@paigemitchell8131 I would call Keurig customer care at 866-901-2739. This could be a known issue Keurig has with this model of Keurig. I have had other viewers with the same thing. When they called Keurig some of them said Keurig knew about this issue and sent them a new Keurig. They have great customer service. I think you will need proof of Purchase. So sorry this happened. I hate it when someone follows my directions and then it breaks their machine. I am so sorry.
@@JustADad Hello, Would you still recommend us to descale our Keurig? If so, use their kit/solution or use vinegar? What do you do?
@@cherylcalifornia125 yes you should descale your machine. I like the Keurig Solution but it is more expensive and sometimes hard to find. I use the Keurig solution.
Just to add, the thermostat or thingy IS RESSETABLE. Just insert tooth pick or paper clip in middle where you see that white circle with power off, then power on, done.
There a reset on the thermal coupler you push it in with a paper clip
Hey, thanks for going, how does it sense water level?... lol, been wondering myself since using the things. I got a dead one out back that I haven't destroyed, I think I will check it out lol! Thanks for doing the teardown, It"s kind of a 'Modern Marel'!
Very cool video! Thanks!
What I'd like to know is, how can you get such a rich, full cup of coffee with so little coffee in those tiny K-cups?
Does anyone know if there is a flow meter to control dispense volume? or is it a timed cycle?
It's now Jan 2024 and I've had my K Supreme for a year. Several months ago it stopped producing the volume assigned to each button, IE, 12oz➡️10oz; 10oz➡️8oz, etc. The deficient value is 2 oz at each setting. All needles have been cleaned multiple times; descaling performed multiple times; factory "reset" performed, deficient volume remains. Logic board vs bad pump vs ?? I found this video interesting as I thought there might be a needle assembly check valve as depicted for other units. Your disassembly of the needle assembly did not show such a valve. Is the line to the pressure transducer supposed to contain water as in your video or be open to atmospheric pressure?
Is your unit running longer for increasing cup size selection or does it shut down after the same amount of time regardless of cup size?
If it shuts down after the same amount of time, I suspect a water flow sensor's signal is not being detected. In this case the circuit stops the brew cycle after the same amount of time. I have a K-910 (no digital display and has a pressure sensor mounted directly on the circuit board). My unit is short cycling after I tried to remove visible scale from the small hose leading to the pressure sensor.
Is there any reason why the water pump will not work even though the lights come on and I can select a cup size?
Can you replace the thermostat? The way you described it makes it sound like it's supposed to act like a fuse.
I looked online and could not find a replacement Thermostat. The wires are soldered on it. Which you could unsolder and solder them on the new one. When this Open up from High temp it does not close. I think its a one time use. it right on the heating element so if it get too hot the Thermostat open up. You could replace it if you can find one.
@@JustADad There is small hole in the middle of the sensor that you can put a paper clip in to reset the sensor.
@@kevinbadeau2858 Thanks so much, If this works do you mind if I do a video on it in the future?
Take the pump apart and you'll see it's has three chambers, or valves. What is curious is there is a cam on the shaft that does not ride or touch anyting, (so it's not a cam) but passes infront of somthing on the circuit board on the side of the pump. How does the different cup sizes? is this the piece that detmindes that.
That rotating "cam" appears to be a magnet that creates magnetic pulses as it rotates (a Hall Effect circuit). Those pulses are counted by the circuit board. Each pulse represents a very small volume of water that has passed through the pump. Each cup size has an associated number of pulses that must be counted when the pump is running. After the specified number of pulses is reached the water pump is turned off and the air pump turns on for a defined period of time to purge the water line and the K-cup of water.
We need to see Keurig K-DUO how it works as they are different.
Its coming soon.
We descale and now it won’t work - unplug let it cool down the right side of machine seems real hot ( wonder why they didn’t put a vent ) . Hope it works this is our second machine from Costco and if the thermostat is broke this one will go back to Costco
My Keurig IA pumping too much water(ie.. 12 ounce overfill my 12 ounce cup, 10 ounce fills my 12 ounce cup).
Have found WHAT controls the amount of water dispensed?
cool video, thx
no sorry
