In my opinion the problem is a bad console aka control panel with very small chance for the control board to be bad too. I would begin with the control panel.
If you need our help to find the right part number, we need the color of the control panel.
Hi - I have a Kitchen Aid Quiet Scrub (white) and I believe that I need a new control panel. My unit only works with the Soak and Scrub option, no other selection lights come on when the button(s) are pressed.
Can someone give me instructions on how to remove the control panel?
