Patrick for Model Number mdb4650aww Dishwasher will not start. lights on touch pad/ control panel some will light up. the extra rinse on left and sanitize on left, and the wash type on the right will light up, but the start and delay neither light nor function. I have tried the eraser on the end of the ribbon trick no change. I am trying to do this repair once so I am trying to figure out if it is the control panel or the control board (pcb), Thanks for your help. If you need additional info just let me know. Patrick
Answer Hello Patrick. Based on the information you provided, it sounds like the control panel 6-919090 is bad and will need to be replaced. If the board is powering the panel, and some of the buttons are not working, you will need to replace the control panel. Hope this helps. Read More...
