The main control board provides power to nearly every component of the dishwasher.

Control boards are often misdiagnosed—make sure you check more commonly defective parts before replacing the main control board.

To determine if the touchpad is at fault, try pressing various buttons on the touchpad. If some of the buttons don’t respond, the touchpad might be defective.

Other manufacturers require that you purchase the touchpad and control panel together. If you cannot replace the touchpad individually, replace the touchpad and control panel.)
