Andrew for Model Number Mdc4650aww serial# 38578774LR All the lights are flashing on the control panel sometimes after 15 or 30 sec the dishwasher will start back up lights stop flashing and maybe run for 10 sec or a few minutes than stop and the lights flash. I thought it was a handle issue because it somewhat broke awhile back. I took the handle out and made sure the micro switches worked checked continuity and pulled the switches out of the handle and plugged the dishwasher back in and the lights just flash. It looks like the lights are flashing a code possibly. Replaced the front control panel #6-920396 and latch assy # W10130698. If i select a cycle doesn't matter and press start nothing happens. When all buttons are pressed on the control panel they light up but the dishwasher will not start a wash cycle. I went in service mode and the unit will enter it but nothing happens no parts are tested drain etc. I just ordered a control board #4379891 .
Answer Andrew, It sounds like you are on the right track with the control board being ordered. This does sound like the issue would be in the control not sending signal to the components to turn on. Read More... Answered by AppliancePartsPros.com | Friday, August 9, 2013
