If your Frigidaire dishwasher starts on its own, the problem is usually in the control area, not a pump or fill part. The most likely cause is a shorted touchpad and control panel assembly, followed by a failed touchpad itself. If button presses are inconsistent or some keys do not respond, that is a strong sign the dishwasher control panel is shorting and the dishwasher turns on by itself without you pressing Start. Next most likely is the control panel, where a relay may have shorted, and after that the user control and display board, which can also fail and send unintended start commands. This kind of Frigidaire dishwasher starts without pressing start issue often shows up as a dishwasher control panel short or dishwasher touchpad not responding properly at the same time. Before ordering parts, test the buttons and note whether some respond and others do not. Then enter your model number on RepairClinic.com to find the exact Frigidaire replacement part for your dishwasher, whether that is the touchpad, control panel, touchpad and control panel assembly, or user control and display board.
01 - Frigidaire 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 - Frigidaire 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.
