Well, there is a website which has a lot of answers for these machines: keurig coffee maker won't power up - Search (bing.com)
However, once I found the appropriate video, I was aghast at the complexity of the fix. You see, all I wanted to do was descale my K-Supreme, and I finally got it out of descaling mode into the ad water/brew mode. The machine ran out of water and within a millisecond, it shut off. I finally found out via the video that I had tripped the thermostat which is deep inside the machine and that shut it off. There is a procedure to reset the thermostat with a paper clip, but to get to that thermostat, you have to pop off 3 panels using flat head and phillips head screw drivers and pray that you don't break something. Now, I was having a major caffeine urge during this process and called the lady in Columbia who said all she needed was my address and she'd send me a NEW K-SUPREME in 3-5 business days. I took her up on it and will keep my old machine to play with if I want to reset the thermostat. Call Keurig and demand a new machine. You may get lucky like I did: 866-901-2739
