I have had this dishwasher about 2 yrs. When I push start button, the drain/cancel button lights up and goes through cycle. I will then press start and the same thing happens everytime. I flipped the breaker and waited a few minutes, pushed start button and same thing. HELP:(
Most likely the problem is a shorted key on the control panel. If you need the correct part number post the color of the control panel.

Here is a tech sheet

It has info on the keypad output.
Check it with a meter for a stuck key etc.
