We are not getting any coffee/water coming out of the machine. Four of the pods used did not have any holes pierced in them.

Symptom: 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. This happened to my brewer two days ago. I have had this unit for about four years and never had a problem. When I called tech support at Keurig they said "it sounds like the pump is shot", but there was nothing they could do and they would not repair it. Instead of the throwing out my $300 coffee maker I figured I would try to fix it myself. After 3 hours of tinkering, I found and fixed the problem, so I am passing on the tip. Since 2.5 of those hours were spent diagnosing the problem, the fix itself is pretty simple. 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. Hope this was helpful. Erik
