Dishwasher buttons/controls not working

If your dishwasher buttons not working issue shows up as a dead keypad, partial response, or a dishwasher control panel not working even though the display lights up, start with the touchpad and control panel. When some buttons respond and others do not, the touchpad is often the failed part, and on some models the touchpad and control panel are replaced together. If there are no lights or sounds at all, check for an incoming power problem first by verifying the breaker, fuse, or GFCI, since a dishwasher has power but will not start only when power is actually reaching it. Next, make sure lock mode, child lock, Sabbath mode, or Demo mode is not preventing normal operation. If the dishwasher touchpad not responding keeps the cycle from starting, inspect the door latch and test the door switch or latch microswitch for continuity, because a failed latch can block the controls. The main control board can also cause dishwasher controls not working, but it is less common and should be ruled in only after the other parts check out. Enter your model number on RepairClinic.com to find the exact replacement touchpad, control panel, door latch, or main control board for your specific dishwasher.

01 - Dishwasher 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.)

02 - Dishwasher 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.)

03 - Incoming Power Problem

If there are no indicator lights or any noise from the dishwasher when it is turned on, it is likely that power is not reaching the dishwasher. Check the circuit breakers and GFCI (ground-fault circuit interrupter) outlets, if applicable, to confirm they have not tripped, or inspect any fuses to confirm none have blown. Plugging the unit’s power cord into a ground fault outlet is not recommended, but such an outlet can be reset to restore power by pressing in the button on the faceplate.

04 - Dishwasher in lock mode

Many dishwashers have a child lock or “Sabbath” feature which will prevent the buttons from being used when the feature is engaged. The dishwasher could also be in “Demo” mode or another mode which prevents full operation. Consult the dishwasher’s user manual for information regarding locking/unlocking the control panel.

05 - Dishwasher Door Latch

If the dishwasher buttons aren't working, it's possible the door latch is malfunctioning and preventing a wash cycle from being started. Inspect the door latch for any damage. you can also use a multimeter to test the micro switch inside the door latch for electrical continuity. If the switch does not have continuity, the switch or latch assembly should be replaced.

06 - Dishwasher 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.
