I need help troubleshooting. My Bosch dishwasher, model SHE6AF02UC/06, will not start. The on/off button works, but it will not start when I press the start button. I cannot change the mode setting because that button also does not work. All I get is a red blinking "30" (the quick wash mode). I have tried turning it off and on, and I checked that the door was completely closed. Please advise.
