We've had this coffee maker for almost one year and the blinking light began a few weeks after we started using it. It was my first coffee maker with a built in grinder, so I have been really happy with the grinder. What's frustrating is when I have to leave for work at 545am and I go to the kitchen to find the blinking light and no coffee, resulting in yet another cup of weak Keurig coffee. We've started sitting heavy cans on top of the lid to give it enough pressure for the sensor inside to work. Very frustrating!
