Some of the buttons on the control panel won't light up at all. If I press normal wash the no heat dry button lights up with it and then I can't press start. No matter what I push (other than drain/cancel) the no heat dry/lock button is on. I've tried unlocking it, turning off the breaker, pushing the sequence normal wash/no heat dry repeatedly. Nothing is working and I NEED my dishwasher. Any clue what to do?? Sometimes if I leave the door open for a week or two it resets.. but only once and then fails again.:confused:
