If your Roper dishwasher lights are flashing or blinking, the machine is usually telling you a key component is not doing its job. The most common cause is a failed heating element or heating element assembly, since the control panel may start flashing when the water does not reach the right temperature in time. After that, check the water inlet valve, which can keep the dishwasher from filling properly, and the door latch, where a bad micro switch can make the dishwasher blinking and not starting or cause dishwasher flashing error lights. Less often, a shorted control board or main control board is behind dishwasher lights flashing. A continuity test with a multimeter is the fastest way to rule out the heating element, latch switch, or valve solenoids. If your Roper dishwasher lights blinking problem is tied to one of these parts, RepairClinic.com makes it easier to match the fix to your exact machine.

01 - Roper 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.

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.
The main 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. Check the owner’s manual for possible fault codes as one of the components may have failed.
