回答“Water or coffee is not dispensing”On my K10 the coffee was not coming out. After attempting to disassemble the Keurig (thanks to Roberto Maldonado for his guide) I discovered coffee grounds in the hose from the water pump, just above the needle for piercing the top of the K-cup. Long story made short, I never needed to disassemble the K10. I believe the problem was that my wife had purchased coffee pods that were not made of plastic. They had a paper top then a bundle of tightly packed coffee beneath. When these were pierced, they forced coffee into the top needle where it eventually clogged. The solution was to bend a paperclip and push it into the top needle to clear the clog. BTW, my K10 is now 7 years old and is working perfectly.
