The coffee brewer just turns off in the middle of a brew. What is wrong?

The only time the Caps can cause this to happen is when the K-Cup ® Pack is overfilled or packed to tightly with coffee.  The water is pushed through the K-Cup ® Pack under pressure.  If the coffee in the K-Cup ® Pack is packed so tight that the water can not get through then the water backs up and the machine turns off.  The solution is to use less coffee or a less fine grind.  The way to test and see if this is what is going on is to run a used K-Cup ® Pack and Cap through your brewer with nothing in it.  It should operate normally and make you a nice hot cup of water.
