Bought this coffee maker last March, and it has been a great unit up until today ( October 18th).  After the coffee brews and it goes into the warmer mode, it keeps beeping and turning off/on/off/on. I noticed last night it just turned on by itself with no water in it. I had to unplug it. Note that the timer was not set. Our older Mr. Coffee was a trooper and lasted for over 7 years. So I hope I can find the receipt and get it exchanged.
