If your Hotpoint dishwasher starts on its own, the problem is usually in the controls, not the pump or motor. The most likely cause is a shorted touchpad and control panel, followed by a failed touchpad by itself, a defective control panel with a stuck relay, or a bad user control and display board. This kind of dishwasher turns on by itself issue can also show up as dishwasher buttons not working, dishwasher controls not working, or a dishwasher touchpad not responding when you press certain cycle or start buttons. A quick check is to press every button on the touchpad and control panel. If some respond and others do not, the touchpad or full control panel assembly is likely the problem. If the buttons seem inconsistent and the unit still starts without pressing Start, the user control and display board may be shorted. Because Hotpoint 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 that fits your machine.
01 - Hotpoint 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 - Hotpoint 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.
