B100 is not pumping water..vacuum problem

SOURCE: Keurig B100 not pumping a cup of water through

in the water tank you have 2 sillicon tube one of them is stretch at maximum and usaly strech in 2. cut the part split and connect it again. the probleme is because the silicon left is propryety when is strech in very hot water. the best way to slove this problem is to find about 1 in of silicon tube of 1/4 or 3/16 iner and put the new parts of tube directly on the bafle and put the original tube in the new on. it just make a link betwen the bafle and the original tube. put teflon tape on the fitting of the bafle to avoid of the new tube spout out from the fitting.//// but take care and other touble can cause this the pump can be jam because the one way valve on the side of the brewer jam open because is to teith in in is body. check all is thing .if you need somthing eles y will comme back on the site soon :0)

The pump is on the right side, has two wires coming out of it, and is connected to the check valve with a silicone hose. When you run a cycle, to brew a cup of coffee, that pump should be pumping air out, which pushes the hot water out of the tank.

So to test it, disconnect the hose and run a cycle to listen and feel for air coming from the pump. If it is not working (frozen due to the water permitted to enter from the failed check valve), you must remove it to dismantle the top part of the pump.

Getting the pump out is a little tricky... as you will see. There is only one philips head ***** holding it in, however, it is not easy to get to. I used a 90 degree angled *****driver, which worked well, after trying many other options.

Once you get it out, remove the three philips head *****s on the top of the pump right near where the hose was connected. Then separate the two sections of the pump. Inside there will be a fitting in the center that spins to actuate the pump. This fitting must be freely moving. If it is not, use WD-40 or a similar product to free the motor.

Clean up all the WD-40 from inside the chamber (so your coffee does not taste like oil) and reassemble. Then test it by running a cycle. The pump should now be working, if not repeat the process until the pump operates.

Since my last post, I have fixed another B100 that had the same issue. Keurig will not sell you a replacement pump or check valve, so you must repair that pump.

Good Luck, I hope this works for you. Erik

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.
