I have a 2012 GE Cafe Series Dishwasher. I did not realize the start button was turned on (shows blue) and I cannot turn it off so it keeps beeping at me as I had shut the door; now have it open, so it will not run. I cannot change the start time. Here in AZ you do not run your appliances at this time of day. Help, the beep is driving me nuts! I do not have a manual.
