    I have two of them, and both have stopped. One makes a very loud noise, but no water moves. The other makes a somewhat louder than usual noise, but not as loud as the other coffee maker ~ and the water flows backwards into the water tank. No idea whether or how to fix them, or to get them fixed.

    Pump runs but water backs into tank. Disassembled as another suggested. Both tubes appear to be properly connected.



    After turning right side up, made 3 cups properly in a row! Maybe this is the equivalent to kicking the machine and it answers back. Or maybe its a water pressure thing alleviated by shaking the machine around a bit.

    My three-month old B70 blows bubbles into the reservoir instead of pumping water into the tank. I got half a cup of coffee the first time this happened. After standing with mouth agape that this could possibly be happening, I tried brewing again and got nothing to come out and the brew cycle never ended... until I turned off the unit. I followed the directions given here and honestly did nothing but take the base plate off and jiggle some silicone tubes. Nothing seemed loose or broken. I put the plate back on and decided to plug it back in for grins. I found myself amazed as the B70 pumped water into the tank and began working as designed. Whew.

    B100 Single Cup Brewing System: When attempting to brew a cup of coffee, a somewhat louder than usual noise occurs and the water bubbles up into access area where water is poured into the machine instead of flowing out the brewing spout. I took the cover off the machine and checked hoses and looked for broken parts but nothing seemed loose or broken. HELP?

This is a very common problem, just call Keurig tech support. Explain the problem and they will send you a replacement unit and you get to keep you old partially functional unit. I bought mine in December 2009 and I'm on my 3rd unit already. They keep having the same pump issue and Keurig just keeps sending me replacement units. Their customer service is great, but I'm beginning to question their quality control.

I have fixed a couple of them by applying a thin layer of keg lube to the silicone flange underneath the water tank. Remove the bottom cover of the brewer and take out the two screws that hold the flange in place. This is where the pump draws water from the tank. Air can get in at that seal and it won't pump water if that happens. Keg lube will make it seal better. I got mine at Annapolis Home Brew dot com. Hope that helps!

You will have to take the unit apart and on the inside of the water tank there is 2 silicone hoses. one of those fell off. you will have to put it back on. mine did the same thing.. hope this helps.

Keurig B100 coffee maker not brewing


KeuSymptom: keurig B100 coffee maker not brewing. If your brewer sounds like it should be brewing but little or no coffee comes out, the problem may be a simple malfunctioning check valve, located on the right hand side of the unit under the plastic cover. If the check valve is clogged or fails, water from the tank leaks into the air pump (located just below the valve) disabling the pump.

The pump that pushes the water out of the tank located on the right hand side of the unit (I included a photo) has a check valve just above it. On my unit the check valve failed allowing water to enter the top chamber of the pump disabling it. The pump was not damaged it just cannot operate correctly with water in it.

Here is the Fix: Disconnect the check valve and make sure it is operating correctly. Mine was clogged with a small amount of mineral deposits, which was cured by a half hour in a glass of vinegar, and a good rinse. Then disconnect the tubing from the top of the pump and run the unit to allowing the water to escape the pump. Make sure there is no water left in any of the tubing between the pump and the check valve, even the smallest amount will disable the pump again. Reconnect everything and it should work.

Keurig b100 does not shoot water in the K-Cup, It


Either it is scaled up and needs to be cleaned or the air pump is bad.

Only pumps out 1 oz. of water into the cup


Try to de-scale and clean the Keurig machine. Use citric acid or purchase a product called De-scale. If the unit is thourghly cleaned and will not pump our water, the pump is out of the machine. Replacement pumps cost about $25.00. Considering the B100 retailed for $338.00 it may be worth it. You can send it out to repair at crystalpure.com. Repairs for an air pump typically run about $50-75 depending on the exact problem.
