Here is a brewer that had mysteriously stopped working so i set out to fix it.

  1. Here she is. Now lets take her apart!
    • Here she is. Now lets take her apart!

    • Be sure to unplug the unit or risk a dangerous electric shock.

    • Remove the water reservoir and the cup rest; set them aside.

  2. Start by removing the bottom cover.
    • Start by removing the bottom cover.

    • These 5 screws hold it on, remove them.

    • This rivet connects the ground rivets to the cover, it will need to be drilled out to fully remove the cover.

    • Do not remove the feet as it is not necessary.

  4. View without cover. Here is the water pump.
    • View without cover.

    • Here is the water pump.

    • Water tank

    • Inlet, remove the two screws as it is attached to the pump

    • Remove these screws to free the pump. once free *carefully* cut the cable ties on the two hoses so it can be removed

    • Once all the lines are free you will need to un-solder the two wires attached to the pump so that it can be fully removed.

  5. And there you have it. If you have a new one you can now install it. Don't forget to replace those zip ties that you cut off.
    • And there you have it. If you have a new one you can now install it.

    • Don't forget to replace those zip ties that you cut off.

    • If you don't have a new one you can try to fix this one by removing these four screws and removing any blockage.

    • Now Keurig doesn't stock spare parts, so unless you can get your hands on another broken machine you will need to fix the existing motor or source a new one. Radio Shack stocks small motors like this, they won't be exact but with a little modification you should be able to get it working.

how do you know if its your water pump not working? when I turn on my keurig, and the not ready sign is on, the water starts running out of the top like it has a K cup in it but it does not. It just needs the water to fill inside to be in the ready state. A couple days ago I was able to brew a cup and now it wont work.. HELP!

Your going to need to be a little more specific. Explain it in detail and I'll have a better idea of what's going on.

Hi Dan.. Happy New Year.

Would you know if this is the only motor in the unit?

I've removed it but would like to test it before I replace it to make sure it is defective.

Any suggestions on how to best test?

My Keurig does work, but it makes a ton of noise like vibrating until the brewing begins. Could this the same culprit?

Do any of you know why a Keurig B77 would shut off when refilling the chamber after brewing? This happens after each cycle. The cup brews, starts filling the chamber then shuts off. When you turn it back on it continues to fill until it reaches the limit. Any help will be appreciated.

I have the K75 and have done all the cleaning tips to be able to get a cup of coffee to brew to the correct level. The problem still is there. I can hear the pump and see the water being sucked down, but then when it starts to brew it dribbles and does not fill the cup. I have tried all 4 level settings and it seems to get stuck on the travel mug size after choosing it and still dribbles but wont reset that cup size and several times of pushing brew and not getting hardly anything out of it. Wondering what might be the issue so I can correct it.

I am having the same problem

I've cleaned the top tube by removal

of the top cover.

I've descaled several times.

I now believe the pump is not

generating enough pressure thereby,

creating a backpressure on initial

start of cycle, driving coffee grounds

back into the needle nozzle thus,

restricting the flow.

When this happens, the machine

times-out & sometimes un-syncs the


These machines do not last more than

2 to 3 yrs without repair.

STAPLES has a heavy duty model

My wife likes these machines

My A-10 BUNN is 35 to 40 yrs old

It's only been rebuilt 1 time.

Next machine will be K-155

I want my A10 BUNN back :-(

I don't want to live in the shed . .

We need a bigger better kitchen

with more counter space . .

@ $40k . . because the coffee machine broke?? ----> GOOD GRIEF! ;-)

Have 2 K40 (like K50, K55) brewers. Same issues as each other. Only the 10 oz (largest) cup size button will activate any brewing. Streams out hot water both the brew area & overflow nozzle. The amount of water out of the front is approx. 20-24 oz (not just 10 oz).

Then there is approx 5 min time before it resets and can do the brew cycle again. Sometimes it only dispenses 4-6 oz out the front on subsequent attempts just after it resets.

One of the brewers may get the descale light coming on sometimes also. The other one has not done that. I tried descaling the one with the intermittent warning light and no difference after 4-5 cycles with 50/50 solution Vin/water. I even recycled the same hot solution through it to aid in descaling. No difference.

I have no idea why only the largest cup size setting does anything. If I press a different size, not only does nothing happen, the unit must be unplugged a minute or so to get it to reset.

Doesn’t sound like the pump or a clog, but open to any info!
