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.
My K10 had two larger screws than the photo. There were Phillips #2 head and could not be retrieved with a magnet when they inevitably fell into a tight space as they were not attracted to magnets. There was also a catch toward the back of the top cover that finally released when an upward force of sufficient force was applied to the bottom front of the cover.
In my case the pump was fine. My problem was coffee grounds in the hose blocking the flow from the pump. The grounds were in the hose shown in Step 4.
