Gaggenau Dishwasher lights flashing or blinking

If your Gaggenau dishwasher lights are flashing or blinking, the machine is usually telling you a key part is not working the way it should. 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. Next, check the water inlet valve, because a valve problem can interrupt filling and trigger dishwasher flashing error lights. A bad door latch or failed micro switch inside the latch assembly is also a highly likely cause, especially if the dishwasher is blinking and not starting consistently. If those parts test good, the problem may be in the control board or main control board, which can short or stop sending power to the right component. For accurate diagnosis, use a multimeter to check continuity where appropriate and compare any fault codes with your owner’s manual. If you need a replacement part, enter your model number on RepairClinic.com to find the exact Gaggenau heating element, heating element assembly, water inlet valve, door latch, control board, or main control board that fits your dishwasher.

01 - Gaggenau 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 - Gaggenau Dishwasher Door Latch

A dishwasher's lights flashing or blinking could indicate a problem with a micro switch inside the door latch assembly. To determine if the micro switch is at fault, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it or the entire latch assembly.

05 - Gaggenau 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.
