F0

Whirlpool Dishwasher

Severity: Moderate

What Does This Error Mean?

Whirlpool dishwasher error F0 means the control board has detected a general system fault or received an unrecognized command. This is often a catch-all code that appears after a power glitch or when internal communication between components breaks down. A reset usually clears it.

Affected Models

  • WDT730PAHZ
  • WDT780SAEM
  • WDT970SAKZ
  • WDF520PADM
  • WDTA50SAHZ

Common Causes

  • A brief power interruption or surge caused the control board to enter a fault state
  • An internal software error on the main control board generated a spurious fault code
  • A wiring connector between the control board and another component has come loose
  • The door was opened mid-cycle and the control board did not reset cleanly
  • The control board itself has a failing component and is generating random fault codes

How to Fix It

  1. Cancel the current cycle by pressing the Cancel or Reset button on the control panel.

    On most Whirlpool dishwashers, pressing Cancel twice starts a drain cycle and resets the error.

  2. Turn off the dishwasher at the wall switch or unplug it. Wait 5 minutes.

    A full power reset clears the control board's memory and often resolves transient fault codes like F0.

  3. Restore power and run a short wash cycle to see if F0 returns.

    If the dishwasher completes the cycle without showing F0, the error was a one-time glitch.

  4. If F0 returns consistently, check all wiring harness connections to the control board.

    The control board is typically behind the inner door panel. Disconnect the door latch wiring and reconnect it firmly.

  5. If the error persists after checking connections, the control board likely needs replacement.

    Bring your model number to an appliance parts supplier to get the correct replacement board.

When to Call a Professional

F0 is often resolved by a power reset and costs nothing. If it returns repeatedly, the control board may be failing. Control board replacement on a Whirlpool dishwasher costs $150 to $280 including parts and labor.

Frequently Asked Questions

Is F0 a serious error on a Whirlpool dishwasher?

Not usually — F0 is often a soft error caused by a power glitch or minor software issue. If it appears once and a reset clears it, there is nothing to worry about. If it appears repeatedly on every cycle, the control board may be failing and needs attention.

Can a power surge cause F0 on my dishwasher?

Yes — even a brief power blip can cause the dishwasher's control board to lose its state and display an error. If you live in an area with frequent power fluctuations, using a surge protector on your dishwasher's circuit can help. Most F0 errors caused by power events clear after a reset.

How do I reset a Whirlpool dishwasher?

The most reliable method is to turn off the circuit breaker or unplug the dishwasher for 5 minutes. Alternatively, press the Cancel button twice on the control panel — this drains the dishwasher and resets the control board. After resetting, wait 30 seconds before starting a new cycle.
