White-Westinghouse Dishwasher lights flashing or blinking

If your White-Westinghouse dishwasher lights are flashing or blinking, the machine is usually telling you something in the wash system is not checking out. The most common cause is a failed heating element or heating element assembly, since the control expects the water to reach the right temperature within a set time. If it does not, the dishwasher lights flashing on the control panel can be the warning. Next, check the water inlet valve, because if the dishwasher is not getting enough water, cycle timing and performance can be thrown off and flashing error lights may follow. A bad door latch or the micro switch inside the latch assembly is another likely cause, especially if the dishwasher is blinking and not starting or stops recognizing that the door is closed. Less often, the control board or main control board is shorted or not sending power correctly. Start with the simpler checks, then test parts for continuity with a multimeter where applicable. Enter your model number on RepairClinic.com to find the exact White-Westinghouse heating element, water inlet valve, door latch, or control board that fits your dishwasher.

01 - White-Westinghouse Dishwasher Heating Element

The heating element heats up the water to operating temperature. If the water doesn’t reach the proper temperature after a set amount of time, a light on the control panel might start flashing. To determine if the heating element has burned out, use a multimeter to test it for continuity. If the heating element does not have continuity, replace it.

05 - White-Westinghouse Dishwasher Control Board

The control board provides power to nearly every component of the dishwasher. It's possible that the board has shorted and is causing the lights to flash or blink unexpectedly. Check the owner’s manual for possible fault codes as one of the components may have failed. If the control board is not sending power to one of the components, it's likely the control board is at fault and will need to be replaced.
