What should I do if the dishwasher won't start?

First, ensure the door is closed and latched firmly. Check that Control Lock is not activated—if the control lock indicator is lit, press and hold the CONTROL LOCK feature for 3 seconds to turn it off. Also verify you have selected a cycle, there is power to the dishwasher, and press the START keypad to awaken the controls after a period of inactivity.
