KitchenAid Dishwasher Error Codes

KitchenAid HE model dishwashers signal or alert you of an error code by flashing the clean light in a certain pattern that identifies the dishwasher error. The light will first flash the function code, then it will pause for 2 seconds and then flash the problem code. As an example, 8 flashes followed by 2 flashes (8-2) means “Drain pump electrical problem” issue. A 5 second pause will occur and then the light will repeat the error pattern. The control panel and buttons are disabled when an error code flashes.
