Jenn Air Dishwasher lights flashing or blinking

If your Jenn Air dishwasher lights are flashing or blinking, the machine is usually telling you something in the wash or safety circuit is not checking out. The most common cause is a failed heating element or heating element assembly, since the control panel expects the water to reach the right temperature within a set time. If it does not, dishwasher lights flashing or dishwasher lights blinking can be the result. Next, check the water inlet valve, because a valve that is not opening properly can keep the dishwasher from filling as expected and trigger flashing error lights. After that, inspect the door latch and its micro switch, since a bad latch can make a Jenn Air dishwasher blink and not start or interrupt normal operation. If those parts test good, the problem may be in the control board or main control board, which powers and monitors nearly every function. Use your owner’s manual for fault code guidance, and test suspect parts with a multimeter when possible. Enter your model number on RepairClinic.com to find the exact Jenn Air heating element, water inlet valve, door latch, control board, or main control board for your specific dishwasher.

01 - Jenn Air 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.
