Chosen Solution
My dishwasher won’t start a wash cycle. All of the front panel buttons illuminate. The drain motor starts when the Drain button is pushed, but the Start/Resume button neither illuminates, nor starts the cycle. The first two times that I pulled it out to check connections, it started after pushing it back in place, but now nothing. I’ve already tried flipping the breaker for a few minutes.
Cause 1 Touchpad and Control Panel First, ensure that the display works. If the dishwasher display is working but the some of the button don’t respond correctly, the touchpad and control panel might need to be replaced. (Some manufacturers sell the touchpad separately from the control panel. 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.) Cause 2 Touchpad First, confirm that the dishwasher display is working. If the display is still working, try pressing some of the touchpad buttons. If some of the buttons respond correctly but others don’t, it is likely that the touchpad is at fault. (Some manufacturers sell the touchpad separately from the control panel. 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.) Cause 3 Main Control Board The main control board regulates nearly every function in the dishwasher. If there is a problem with the main control board, it might not send voltage to the dishwasher touchpad, causing the touchpad buttons not to work. Control boards are often misdiagnosed; make sure you test more commonly defective parts before replacing the main control board.
