Some Whirlpool dishwashers display an error code by flashing the clean Light on the display in a pattern. If your Whirlpool dishwasher does NOT have a digital display, the clean Light will flash the function code then the clean Light will pause for 2 seconds and then will flash the problem code. You need to count the number of times the clean light flashes to find out the error code on your Whirlpool dishwasher. As an example: If the clean light flashes 5 times followed by 2 flashes (5-2) then this error is showing the function code = “Door issue” and the problem code is “The door switch is in question”. The flashing light patterns repeat again after a 5 second pause. NOTE: The control panel console is fully non-functional when an error code is flashing.
NOTE: You may attempt to run a diagnostic test cycle to find errors. Beginning the test cycle is different on dishwasher models.
Try the action below to run a diagnostic test on your dishwasher:
1 – Turn the dishwasher on.
2 – Press the rinse cycle button.
3 – Turn the dishwasher back off.
4 – Hold down the start button while you turn the dishwasher back to on.
5 – When the light starts flashing immediately let go of the start button.
6 – Press the start button one time and shut the dishwasher door.
7 – The test cycle should start.
8 – If an error is found the cycle will stop, the flashing error code will then display.
