I received a Keurig B60 Special edition brewer as a gift about 6 years ago and it has worked flawlessly. Recently I needed a coffee maker at work so I brought it to the office and purchased another Keurig - the B70 Platinum - at Costco. A couple of weeks ago it started acting up. After brewing a cup I would hear the pump come on to fill the heating chamber but after a few seconds the water would not pump and the Prime indicator would come on. I removed the water reservoir, reseated it and then the brewer functioned normally. After 1 or 2 brews, the same thing would happen. I did some searching and found that this seemed to be a common problem with several different solutions. I tried them all but the problem persisted. I called Keurig last evening, explained the problem and without hesitation they are sending me another brewer. The B70 is no longer available so I am getting the new 2.0 K550 model which brews sincle k-cups as well as the new 4 cup pods. Keurig doesn't even want me to return my brewer. All they want returned is the k-cup holder out of the brewer. I'm not sure if I will like the K550 as I've read some comments indicating that the brewed coffee is not as hot and that this new brewer also 'reads' the k-cup (like a Tassimo) so that only official k-cups will work in the brewer.
