Thermador Dishwasher lights flashing or blinking

If your Thermador dishwasher lights are flashing or blinking, the machine is usually telling you the water is not heating as expected or a key safety or control component is not responding. The most common cause is a failed heating element or heating element assembly, since the control panel may start flashing when the dishwasher cannot bring water up to the proper temperature. Next, check the water inlet valve, because low or no water flow can also trigger Thermador dishwasher flashing error lights. After that, inspect the door latch and its micro switch, since a bad latch can make the dishwasher lights blinking issue look like a startup or cycle fault. If those parts test good, the problem may be in the control board or main control board, especially if the dishwasher is blinking and not starting or the lights flash unexpectedly during a cycle. Using a multimeter to check continuity on the heating element, latch switch, and valve solenoids can help narrow it down. Enter your model number on RepairClinic.com to find the exact Thermador replacement part that fits your specific dishwasher.

01 - Thermador 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.

04 - Thermador Dishwasher Door Latch

05 - Thermador 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.

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 main control board is at fault and will need to be replaced.
