I got one of those keurig coffee makers and the other day it started acting funny and started spewing water out after my coffee was made.
I unplugged it. After a bit I plugged it back in and all the lights were blinking and nothing worked.
found on another forum, a trick to reset the computer.
press the auto off button and both cup size buttons at the same time and it resets.
all the lights went out and I was able to make a cup of coffee.
Now as long as it doesn't start spewing water again at the wrong time....
