If your GE dishwasher starts on its own, the problem is usually in the control area, not the wash system. The most common cause is a shorted touchpad and control panel, which can make the dishwasher turns on by itself or starts without pressing Start. A bad touchpad by itself is another likely cause, especially if some buttons do not respond when pressed. Next, check the control panel, since a shorted relay there can also trigger a GE dishwasher starts on its own complaint. If the buttons seem inconsistent but the panel looks fine, the user control and display board may be failing and sending the wrong signals. In many cases, a dishwasher control panel short or a dishwasher touchpad not responding will show up before the unit begins starting by itself, so testing button response is a good first step. Because GE models vary, enter your model number on RepairClinic.com to find the exact replacement part for your dishwasher, whether that is the touchpad, control panel, or user control and display board.
01 - GE 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.)

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.
