Whirlpool Dishwasher Error Codes – Lights Blinking Flashing







Whirlpool dishwasher displaying an error code or flashing lights? If your dishwasher detects an error in the system, it will show an the appropriate error, the lights flash, will blink, or a fault code will show. When lights are blinking your dishwasher is identifying a specific fault. The light blinking sequence will indicate which part on your Whirlpool dishwasher needs to be replaced.

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.

Our less than 2 yr old dishwasher is blinking between E2 and F2.
From above F2 states a water leak has been detected.
What does E2 mean?

Whirlpool Quiet Partner III starts to fill with water but stops just shy of the heat element. There is a slight buzzing sound but the machine will not progress beyond this point. I have run the diagnostic but get no code. No flashing lights. The machine will drain.

John,
If trying to reset the Whirlpool dishwasher panel does not work and it continually blinks or flashes, it is your control panel keypad assembly that has gone bad or a stuck key is causing the issue.
