Thank you for your generous tutorial. My Keurig Duo was clogged with debris from my water filter! Rock hard little pieces that prohibited any/all water flow. The machine was only a little over a month old & I tried everything to unclog it. At the time, I had no idea what caused the clog. It was several months later that I saw white particles in a glass of water and put it together. Fast forward about a year - I was working in my garage and saw the Keurig box. I thought, “surely there is a way to get inside and clean the debris out of the system”. I watched a couple of videos but not until I found yours did I have the confidence to get after it. Mine is a bit different from yours but the process was close to the same. Wow! After sitting for months with vinegar in the system, I was able to disconnect a couple of hoses/tubes and blow out the watery vinegar - along with milky debris. Before putting it back together, I plugged it in and voilà! It works beautifully! Thank you again for your help. I am grateful.
@WhittakerOutdoors So I fixed mine by taking all of the back plastics off and found a huge clump of calcium buildup and took the hose off and ran it to get the stuff out.
Thanks for the tutorial! Your description helped me get the case off & only one clip broke. Your explanation of the parts also helped me understand how the water flowed through the machine. I was able to squeeze the tube running from the water level sensor to move the water out of the sensor to find out that wasn't the problem. I did that a few times to engage the pump to push more water through. That may have been enough to kickstart it again. In the end, it might also have been the vinegar sitting in the tank for a few weeks that eventually descaled the heating tank enough. I thought I was never going to get rid of the "DESCALE" light!
Thanks for this video. Mine was showing the 'Add Water'. After watching this video I was able to take it apart and do some testing. I blew out the vent tube then put the tank on temporarily and saw the water rise in the tube. I tested continuity across the leads at the water level sensor (you have to disconnect the cable from the board first or you will get a false positive) and had continuity so I put it back together and it is working now.
Mine was making small amounts of coffee on the pot side and full cups on the k-cup side.. after hours of trying different solutions these videos shared, nothing worked.. took it apart and blew the vent tube out with compressed air, works perfect now!
This video was good for me getting my Duo mostly apart, except that I couldn't get the two hidden screws @1:30 out. The tabs are just stuck right in there. I might resort to extreme force because it's otherwise not useable. The Duo turns on and lets you select what coffee to brew, but it doesn't do anything with the water or react like it's trying to brew. It doesn't complain it's out of water, just doesn't do anything with water. I can't descale because it won't take any water. I can't tell if my model has a thermostat. Mine doesn't have a water filter.
At 7 42 of this video it shows some type of pump I think.I took the clear hose off at the bottom and slid it thru to the other side where it runs into the tank that heats the water.That hose was full of calcium deposits .I then took a greenish plastic closeline that has wire in the middle and cut off an inch of plastic at the end exposing the wire.I then ran this thru the hose to clean it out. I then ran the hose back thru(I USED A NEEDLE NOSE PLIERS AND SCREWDRIVER) and hooked it up and amazingly the coffeemaker actually works. Thanks for this video showing me how to open this thing up..
The reason for the coffee maker brewing a low amount compared to the selected is due to scale buildup. Watched best buy repairman take mine apart and we found that many tubes and the water reservoir looked quite similar in appearance to plaque clogged arteries. They replace the thing due to how clogged mine was
Usually caused by using hard water or tap/soft water through the system. Best to used filtered or bottled water if you want to keep the hoses clearer and cleaner over an extended time, because continuing to use the same water will cause the same issues again and again regardless how much descaling is done. We put a filter on our sink and it’s made a big difference with how much better my Keurig machine lasts compared to how it was prior. I’ve had an issue with one light not working, found this video on how to take it apart, and was surprised at how clean the hoses were. Makes a huge difference.
My recent experience involved two Duo units. The first one worked properly on the carafe side but not on the pod side. I bought a used one that ended up with just the opposite problem. After disassembling the second one and just blowing/sucking on all the hoses and valves it is working properly now. I could see nothing wrong anywhere, however when it was brewing a carafe before the water seemed to not flow evenly and it had spurts of steam. Now it brews quietly without any spurting noises. Maybe it was an airlock somewhere.
I also turned the unit upside down and drained the tank by disconnecting the upper and lower tank hoses. It’s possible that the contacts inside the tank that measure the water level were calcified. Maybe a suggestion is to inject vinegar directly into the tank. Fill it then let it sit overnight?
Thanks for this! mine seems to have a clog. I did remove the five screws from the bottom, but was unable to pry the shield off. After watching your video, I feel I will be able to do that and it looks fairly simple inside, as far as the tubes go. I am hopeful that I will get it working again!
Thanks for the disassembly video. I found the very small six contact flat ribbon cable at the lower board, that goes to the control board up top had a burnt out trace at the lower connection. Causing no power at the control board up top. I verified by scraping away the contact insulation at the trouble end, very difficult to do, and re-engaging. The clock and buttons returned, but I was unable to make all the functions return. I was not able to get all the ribbon cable contacts cleared of insulation. I'll try to replace the ribbon or substitute next.
A couple notes!! First of all thank you for the video. The bottom part to get off was a little confusing from the video. After removing the screws, that piece will SLIDE to be removed. No need to pry. If the machine was in its normal position on your counter it would slide straight down towards the counter, in that direction. The part where you use a pick to get the two caps off to access the screws, I just used some strong duct tape pushed down on the circle piece and pulled them straight out. Now, that same piece with only two screws holding it in should then be removed AFTER the top piece is removed. Or you will break the little tabs on it. If you break them like I did, not the end of the world though. My problem was the top vent hole had a film over it not allowing it to vent. It does seem like that top piece might be able to be removed without taking the whole thing apart by sliding it straight backwards if you’re in front of your machine on the counter in its normal position. But not positive. It just looked like it when I was observing it. Hope this helps!
Thanks, took mine apart and metered one side of the wall plug to where it mounts on the circuit board, after it goes through the thermal fuse. It had no continuity so my thermal fuse is open. Ordered one online.
Here's the problem with diminishing production - 10 yields 8, 8 yields 6 and slowly a trickle or nothing at all. If you have hard water, and mine must be among the worst in the world, lime will form at the bottom of the heating barrel, like a layer of white mud. This in turn will plug the opening where the tube runs from the bottom of the heating barrel to the pump. And the water can't be pumped. Moreover, the tube will also silt up full of white mud because when the pump stops, there is no check valve and some of the water will drain from the heating until back into the tube. If you want to clean the mud out, you must remove the heating unit. It comes apart in two halves by means of a series of machine screws. You can then clean it and the tube. But to get the heating unit out is a devil. You must split the plastic case of the machine into 2 pieces so you can separate them, like opening a book. The plastic case, once the screws are removed as you illustrate, is held in by plastic tabs. You must find them all and pop them so the top and bottom (2 pieces of the machine) separate. Then you have to pull some of the wires and rubber hoses that prevent you from getting them apart. At that point, you can get at the heating unit. If attempting any of this, make sure you label all the tubes and any wires separated so you know where they go. While I did this, I did a wretched job. Thankfully, this video helped me figure out the last 2.
Thank you for the video, it was very helpful 👍!! Thought I might share my experience, fixing mine (yes, yes I did!) hoping it too may help someone. So I tore into it, little plastic ears flying like shrapnel, then I put the claw hammer down, jk. Once I had the shrouds removed, I noticed the check valve device (which can be seen at 4:23 attached to the water intake) was dark looking, like some foreign matter was in it. You may be wondering what it was; algae maybe…mold possibly….hmm, something impervious to white vinegar, possibly black calcium…no no that is not a thing….dark matter!?! No, freakin’ coffee grounds. How in the blankety-blanking-blank-blank did they get in there!! Me, bleary eyed, oafishly making coffee at the crack of dawn!? I think not…as I give the rest of my family side eye…regardless it needs fixing, and I’m just the guy to get very frustrated and drop kick the damn thing in the yard and shoot it with my shotgun; but I’m a tightwad…so I take it apart and commence to shake, and blow, and squirt, and spray, and cuss, and wiggle, and pray, and beg….finally taking tweezers, pulling down on the spring loaded diaphragm; whilst simultaneously running water and chanting an incarnation I got it empty of grounds!! Yay me!! So I reassemble everything annnnnnd, it now does nothing. I begin to think, well coffee is expensive, and caffeine can be mildly addictive, and I’d rather be doing something else: no-no, man up and get the claw hammer out, then go to Wal-mart for the next victim…yeah, but I’m a tightwad. So back in I go. I remove a hose, and prime the heating reservoir, and try to purge air, from where it had been turned upside down when removing the screws. WARNING: ⚠️ do as I say, and not as I do-things attempted in this comment are not to be emulated in your home. ⚠️WARNING. So with the shroud off, I plug it up. Yes mom, I know it’s dangerous…and when I get done with this, I’m gonna run up and down the stairs with scissors in both hands!!(warning, don’t do that either)
Damn, I’m long winded…how many characters per comment? Oh, well…after getting home from the hospital from the scissors incident…no not really. With the shroud off, and the thing plugged in…oooooooo(scary voice)…I run a cycle, and nothing. So I take the vent line loose and using a veterinarian syringe I force water into the pump, then I squeeze the outlet hose on the pump, until the airlock is displaced. I do this while the pump runs. Now, the coffee POT!! (not carafe, but POT!! I’m a dadgummed ‘Murican…and I pour from a POT!!; but I digress) fills up!! 🎉whoo-hoo🎉; however the pod, cup side, only about half-but hey ya can’t have it all, and besides them pods are for rich, fancy folks-like my wife, my kids, my parents, her parents-wait a darn minute! I’m the one buying them, oh well-I’ll stick to my POT!! Bet they all say carafe too, while sticking out their pinkies sipping their dadjimmed pod coffee. Anyway, when reassembling this time, I did not invert the machine; rather I set it on the edge of the counter and knelt down craning my neck, biting my tongue, furrowing my brow and put the little screws back in-which was fun compared to putting the shroud back on with the machine upright, but I won’t bore you with that. Well, I reckon you can tell I have way too much time on my hands. Hope this was helpful to anyone who took time to read it, rather than throwing up there hands and saying “I don’t have time for this malarkey!! I NEED COFFEE!!” Well, good luck, unless you call a POT!! a carafe, then you can take your hoity-toity self to Starbucks!! If you see my family there, say hi for me and tell them I just opened the credit card bill and I’m headed for the stairs with scissors in hand and an dejectedly apathetic expression.
i have a 5100 which wont power on at all just like yours. i might try and find a used board if it's worth my time. but i can desolder and solder easily if i knew the exact component, aside from a smc chip of course.
Thank-you! Its really helped. But at around the 2:10 mark of your video, you sort of jump though how the last top back panel comes off. Do you have some extra video that shows that better?
Love the video mines stopped turning on today. I did opened it trying to find a restart button and no luck. Will have my husband see this video to see if we find the answers.
At 7:08. The 8 pin IC chip (U4) is fried. The IC chip is bubble on top from overheated. This circuit board ( where U4 is resided) looks like a low voltage power supply around 12VDC. It supplies the OMRON 12VDC relay, a small black square box, next to larger white OMRON 12VDC relay. Just get the small 110V to 12V DC wall plug, can be either transformer type or switching power supply (much lighter in weight, and small to fit the space). Remove the circuit board. Solder 110V side to large black and red wires and output 12VDC to small black (Negative) and red (positive) wires. I bet a dollar to donut, the coffee maker will work again.
BTW, the IC chip looks like a 555 IC timer (not 100% sure from the video) which generally used for this type of application. The IC is $0.14 (amazon $7 for 50 pcs), can be de-soldered and easily replaced.
Hi, I have a k duo 5100 that will power on and size cups blinks and are selectable , the start button is blinking but when start, instead of the slow glow doesn't do the gradual bright to dim as our other does and doesn't recognize if tank is full or empty and can't power off. after normal time that should have made a cup, the size goes off and select cup or pot alternates again and can select and start again but doesn't heat or pump. Either the cup or carafe. suggestions?
I have followed all of your steps and I have the k duo that looks just like this, but where you’re showing where the water is directed to the carafe any direct and the other tube directs it to the single serve. I have a part that looks like you’re missing.??? I dunno. How do I send you a photo of what I’m talking about???
You have to use distilled water or you get sediment in hose system which makes the water regulation system faulty. So you won't get proper water quantities.
@JustADad How about you have been successful in repairing the coffee maker? I have exactly the same problem, the thermostat works and passes power, I disconnected and connected everything and everything looks fine, thanks for the help.
I love my keurig it’s a duo k cup but for the last week not long after I turn it on it starts to over heat and smoke comes out so I quickly unplug it. Is there any fixing it?
A microwave oven. :O) Seriously, if the heating element is shot, I've no clue where to get another one. I'm sure Keurig won't sell you one because they want you to waste another $300 on a new coffee maker. I'd suggest Mr. Coffee for about 30 bucks.
I have the opposite of the common problem you mentioned: if I select 8oz it brews 10oz or more, if I select 10oz it almost overfill very large mugs, and the coffee/water ratio is whacky.
I have the same issue, Keurig support says the unit is unable to be fixed for what that is worth. I assume it is some sort of timing issue similar to the producing too little issue. Likely a dying electrical component/board :/
The "box" at 4:26 has a spring actuated valve at the end, the black circle part has one as well. If I have the box and black parts in my hand as one unit disconnected from the tubes, and if I blow though it's intakes. What should I expect it to do? I believe my was jammed. Thanks, I currently have my keurig in bits, it stopped working 8 days outside of warranty! 😂😂😂 also it might be dumb but is your ribbon wire that goes from the circuit board to the controls on the lid disconnected?
Excellent video for guys that just want to fix things, like me. Howerver the real trick is stay away from the Cuisinat and Keurig duo models or hope that it fails in warranty at which time they will replace them for free or just get used to buying another one evey 2-3 years, I've had 3 Cuisinarts and one Keruig replaced for free. Good policy but their products are cheap imports. Nothing lke years ago.
My duo is turning on, allows a kraft selection, but when I push the start button - nothing happens, it just freezes with no response from any of the buttons. Any ideas for this problem? It just started after working normally. Thanks in advance!
Do you know of any reason why when I hit the button on my Keurig duo nothing happens the pump doesn’t turn on or anything the machine set for roughly 2 months not being used and when we went to use it again, it would not work
Is there 2 pumps on a kurig,? The pump filling the reservoir works great, HOWEVER, when it pumps water to the coffee pod it starts fast, then slows to a trickle ( I tested it by removing the top, and pried off the plastic hose, everything is very clean, and tested the water flow coming directly from the clear plastic hose. Water uns fast for 3 seconds, then slows to a drip. Any suggestions?
I've got a rather peculiar issue with a K-Duo. The air pump will not energize. I can use my DC benchtop supply and energize the pump and it will run just fine, forcing the selected amount of water through the lines before the shutoff valve stops the flow of water. I've disconnected the air pump and tested for power at the actual socket on the logic board, and I get around 11.8VDC when the machine sends the signal to engage the air pump. If I have the air pump connected, and I attempt to measure voltage at the leads at the top of the pump, I get nothing. I've ruled out the wiring harness by desoldering it from the pump and measuring voltage at the ends when the machine sends the signal to engage the air pump and I get the same 11.8VDC. I've also tested inserting some solid copper wires into the female socket of the wiring harness and have successfully powered the pump with the benchtop supply set at 11.8VDC. I'm incredibly stumped.
Thank you! Very much I’m a female and had no problem following your instructions. I have the kcup duo plus maker with the full coffee pot option and this worked for my model as well.
I just had the same failure with the same model. It's just dead. I called Keurig and they replaced it, but I was hoping there might be an easy fix for the broken one. I guess not...
ever have any luck figuring out why the carafe side doesn't make as many cups as it should? I've got mine torn apart trying to troubleshoot the dang thing!
No, but some viewers have, they blow air in the lines to clean them out around the pump and that has worked, one viewer used a syringe to pump water in the lines where the water tank is the that helped get his going again. the Duo's are just hard to fix.
My Duo won’t power on, then it will and the clock and the U under the K flash and the power light is steady. The clock won’t set and the othe buttons won’t do anything. Then it won’t turn off, and after a while it does. I’m thinking it’s the motherboard.
I know this comment is completely irrelevant to the topic at hand but I couldn’t help but notice your fingernails. A lot can be said about a persons health based on their fingernails alone. Judging from your healthy lunula 🌛 (half moon shape) at the base of your nail indicates that it’s likely you do not have vitamin deficiencies, kidney problems, inflammatory or metabolic illness, lung or heart disease, diabetes, fungal infection or even depression. 😊
So mine looks like this one and it stopped pumping water. I took it apart and it seems like the pumps are working fine I just don't know how to fix it. It's not taking water out of the tank.
Thank you for your generous tutorial. My Keurig Duo was clogged with debris from my water filter! Rock hard little pieces that prohibited any/all water flow.

Thanks for sharing, good job getting it back running!
Which hose did you blow into with air?
Which hose did you blow out with air?
@WhittakerOutdoors So I fixed mine by taking all of the back plastics off and found a huge clump of calcium buildup and took the hose off and ran it to get the stuff out.

You sir!!!! This is how to show an engineer what to fix!
Great video. Had a add water light when reservoir was full. Found out the vent was clogged. Cleared it and it worked. 👍
Excellent!
Hey stranger, your comment just helped me fix mine. It was having the same problem. Thanks so much!

Anyway, when reassembling this time, I did not invert the machine; rather I set it on the edge of the counter and knelt down craning my neck, biting my tongue, furrowing my brow and put the little screws back in-which was fun compared to putting the shroud back on with the machine upright, but I won’t bore you with that. Well, I reckon you can tell I have way too much time on my hands. Hope this was helpful to anyone who took time to read it, rather than throwing up there hands and saying “I don’t have time for this malarkey!! I NEED COFFEE!!” Well, good luck, unless you call a POT!! a carafe, then you can take your hoity-toity self to Starbucks!! If you see my family there, say hi for me and tell them I just opened the credit card bill and I’m headed for the stairs with scissors in hand and an dejectedly apathetic expression.
i have a 5100 which wont power on at all just like yours. i might try and find a used board if it's worth my time. but i can desolder and solder easily if i knew the exact component, aside from a smc chip of course.
Thank-you! Its really helped. But at around the 2:10 mark of your video, you sort of jump though how the last top back panel comes off. Do you have some extra video that shows that better?
Love the video mines stopped turning on today. I did opened it trying to find a restart button and no luck. Will have my husband see this video to see if we find the answers.
keep me updated.
At 7:08. The 8 pin IC chip (U4) is fried. The IC chip is bubble on top from overheated. This circuit board ( where U4 is resided) looks like a low voltage power supply around 12VDC. It supplies the OMRON 12VDC relay, a small black square box, next to larger white OMRON 12VDC relay. Just get the small 110V to 12V DC wall plug, can be either transformer type or switching power supply (much lighter in weight, and small to fit the space). Remove the circuit board. Solder 110V side to large black and red wires and output 12VDC to small black (Negative) and red (positive) wires. I bet a dollar to donut, the coffee maker will work again.
BTW, the IC chip looks like a 555 IC timer (not 100% sure from the video) which generally used for this type of application. The IC is $0.14 (amazon $7 for 50 pcs), can be de-soldered and easily replaced.
Hi, I have a k duo 5100 that will power on and size cups blinks and are selectable , the start button is blinking but when start, instead of the slow glow doesn't do the gradual bright to dim as our other does and doesn't recognize if tank is full or empty and can't power off. after normal time that should have made a cup, the size goes off and select cup or pot alternates again and can select and start again but doesn't heat or pump. Either the cup or carafe. suggestions?
Can you bypass the thermostat if it is bad & use it that way safely ?
The thermostat is a safety device. You can always bypass safety devices, but future use will not be safe.
@@hamburglurgl Thank You 👍🏼
I have followed all of your steps and I have the k duo that looks just like this, but where you’re showing where the water is directed to the carafe any direct and the other tube directs it to the single serve. I have a part that looks like you’re missing.??? I dunno. How do I send you a photo of what I’m talking about???
You have to use distilled water or you get sediment in hose system which makes the water regulation system faulty. So you won't get proper water quantities.
@JustADad How about you have been successful in repairing the coffee maker? I have exactly the same problem, the thermostat works and passes power, I disconnected and connected everything and everything looks fine, thanks for the help.
I love my keurig it’s a duo k cup but for the last week not long after I turn it on it starts to over heat and smoke comes out so I quickly unplug it. Is there any fixing it?
Any advice on how to fix the carafe warming plate?
A microwave oven. :O) Seriously, if the heating element is shot, I've no clue where to get another one. I'm sure Keurig won't sell you one because they want you to waste another $300 on a new coffee maker. I'd suggest Mr. Coffee for about 30 bucks.
I have the opposite of the common problem you mentioned: if I select 8oz it brews 10oz or more, if I select 10oz it almost overfill very large mugs, and the coffee/water ratio is whacky.
I have the same issue, Keurig support says the unit is unable to be fixed for what that is worth. I assume it is some sort of timing issue similar to the producing too little issue. Likely a dying electrical component/board :/
The "box" at 4:26 has a spring actuated valve at the end, the black circle part has one as well. If I have the box and black parts in my hand as one unit disconnected from the tubes, and if I blow though it's intakes. What should I expect it to do? I believe my was jammed. Thanks, I currently have my keurig in bits, it stopped working 8 days outside of warranty! 😂😂😂 also it might be dumb but is your ribbon wire that goes from the circuit board to the controls on the lid disconnected?
Excellent video for guys that just want to fix things, like me. Howerver the real trick is stay away from the Cuisinat and Keurig duo models or hope that it fails in warranty at which time they will replace them for free or just get used to buying another one evey 2-3 years, I've had 3 Cuisinarts and one Keruig replaced for free. Good policy but their products are cheap imports. Nothing lke years ago.
My duo is turning on, allows a kraft selection, but when I push the start button - nothing happens, it just freezes with no response from any of the buttons. Any ideas for this problem? It just started after working normally. Thanks in advance!
Same for me. Another video I found has a guy mess with the k cup door switch which did nothing for me.
I don’t know why I was recommended this video but good luck to everyone trying to get back to the coffee :)
Thanks for watching
Mine pumps the water to the k cup but doesn't run thru the pod? I don't know what to do
Do you know of any reason why when I hit the button on my Keurig duo nothing happens the pump doesn’t turn on or anything the machine set for roughly 2 months not being used and when we went to use it again, it would not work
I have the same problem. Did you find a solution?
Mine keeps overfilling cups. Any suggestions?
Is there 2 pumps on a kurig,? The pump filling the reservoir works great, HOWEVER, when it pumps water to the coffee pod it starts fast, then slows to a trickle ( I tested it by removing the top, and pried off the plastic hose, everything is very clean, and tested the water flow coming directly from the clear plastic hose. Water uns fast for 3 seconds, then slows to a drip. Any suggestions?
I have the same problem. Did you find a solution?
My duo is spewing water in the k-cup side all the time, I assume the water pump has some junk in it or it is broken.
How to you reconnect hose at the bottom of water tank
I've got a rather peculiar issue with a K-Duo. The air pump will not energize. I can use my DC benchtop supply and energize the pump and it will run just fine, forcing the selected amount of water through the lines before the shutoff valve stops the flow of water. I've disconnected the air pump and tested for power at the actual socket on the logic board, and I get around 11.8VDC when the machine sends the signal to engage the air pump. If I have the air pump connected, and I attempt to measure voltage at the leads at the top of the pump, I get nothing. I've ruled out the wiring harness by desoldering it from the pump and measuring voltage at the ends when the machine sends the signal to engage the air pump and I get the same 11.8VDC. I've also tested inserting some solid copper wires into the female socket of the wiring harness and have successfully powered the pump with the benchtop supply set at 11.8VDC. I'm incredibly stumped.
My burner isn't working for the 12 cup crafte . Does anyone have a video to fix?
Thank you! Very much I’m a female and had no problem following your instructions.
I have the kcup duo plus maker with the full coffee pot option and this worked for my model as well.
question when I run the water cleaner in the craff side I have noticed that it never finishes and reaches the desired selection
This could be a known issue Keurig has with this model of Keurig. I would call Keurig Customer Care at 866-901-2739.
I took mine apart and cleared the vent tube put it all back together and now only the lights come on but it won't do anything
I just had the same failure with the same model. It's just dead. I called Keurig and they replaced it, but I was hoping there might be an easy fix for the broken one. I guess not...
ever have any luck figuring out why the carafe side doesn't make as many cups as it should? I've got mine torn apart trying to troubleshoot the dang thing!
No, but some viewers have, they blow air in the lines to clean them out around the pump and that has worked, one viewer used a syringe to pump water in the lines where the water tank is the that helped get his going again. the Duo's are just hard to fix.
I’ve had the problem of not getting the amount of water selected. I found it was due to overfilling my reservoir.
have you descaled it lately?
My Duo won’t power on, then it will and the clock and the U under the K flash and the power light is steady. The clock won’t set and the othe buttons won’t do anything. Then it won’t turn off, and after a while it does. I’m thinking it’s the motherboard.
I replaced the motherboard, and got one from eBay fairly cheap it worked back again
Now a view to put the back plate back on please
It looks like IC U4 is damaged. Looks like a burn mark on top of IC.
what about the waffle makers comparison
Ok I will add it to the list
Why would water work o kcup but not carafffe
The needle is why it doesn't give enough water
That U4 chip looks cracked
I know this comment is completely irrelevant to the topic at hand but I couldn’t help but notice your fingernails. A lot can be said about a persons health based on their fingernails alone. Judging from your healthy lunula 🌛 (half moon shape) at the base of your nail indicates that it’s likely you do not have vitamin deficiencies, kidney problems, inflammatory or metabolic illness, lung or heart disease, diabetes, fungal infection or even depression. 😊
So mine looks like this one and it stopped pumping water. I took it apart and it seems like the pumps are working fine I just don't know how to fix it. It's not taking water out of the tank.
maybe prime the pump, fill tank with water and lift it on and off the machine about 20 times to push water into the machine.
