Dishwasher starts on its own
If your dishwasher starts on its own, the problem is usually in the controls, not the wash system. The most common cause is a shorted touchpad and control panel assembly, followed by a failed touchpad by itself. In many cases, you can confirm it by pressing each button and checking whether some keys do not respond, which is a strong sign the dishwasher touchpad is shorted. Next most likely is a defective control panel with a stuck or shorted relay, and after that, a bad user control and display board that is sending start commands when it should not. This kind of dishwasher turns on by itself issue can also look like dishwasher starts without pressing start or a dishwasher control panel short. Since some brands sell the touchpad separately and others require the full control panel assembly, it is important to match the part to your exact machine.

01 - Dishwasher Touchpad and Control Panel
If the dishwasher is starting on its own, part of the touchpad may have shorted. 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. (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.)

04 - Dishwasher User Control and Display Board
A dishwasher's user control and display board allows the user to select a wash and drying cycle and start the appliance. If the dishwasher is starting on its own, it's possible the board has shorted and will need to be replaced with a new one.
