F3
Whirlpool Dishwasher
Severity: CriticalWhat Does This Error Mean?
The F3 error means the wash pump motor in your Whirlpool dishwasher is not working correctly. The wash pump is what circulates water through the spray arms to clean your dishes. Without a functioning wash pump, the dishwasher cannot clean anything.
Affected Models
- WDT750SAHZ
- WDF520PADM
- WDT970SAHZ
- WDTA50SAHZ
- Most Whirlpool built-in dishwashers
Common Causes
- The wash pump motor has burned out or seized
- A piece of broken glass, food debris, or foreign object is jamming the pump impeller
- The wiring harness connection to the wash pump motor is loose or corroded
- The control board has failed and is not sending the correct signal to start the pump
- The capacitor that helps start the pump motor has failed
How to Fix It
-
Turn off and unplug the dishwasher, then remove the lower rack.
Always disconnect power before reaching inside the dishwasher.
-
Remove the lower spray arm, filter cover, and filter assembly.
Twist the spray arm counterclockwise to remove it. The filter unscrews from the center of the tub floor.
-
Inspect the filter and sump area for debris — glass, bones, fruit pits, or broken plastic.
Even a small piece of debris can jam the pump impeller and trigger F3. Clear out anything you find.
-
Reinstall the filter, restore power, and run a short cycle.
If F3 was caused by a debris jam, clearing it may resolve the error.
-
If F3 returns, the wash pump motor itself likely needs to be replaced.
This is a job for a technician unless you are comfortable with appliance repair. The pump sits beneath the tub and requires disassembly to access.
When to Call a Professional
Wash pump replacement is a moderately complex repair. The dishwasher usually needs to be pulled out and tipped to access the pump. Pump motor assemblies cost $80–$200 in parts plus labor. For older dishwashers, compare this against the cost of a new unit.
Frequently Asked Questions
Can debris really stop a dishwasher pump?
Yes. A small shard of glass or a fruit pit can wedge in the pump impeller and stop it completely. Always check the filter and sump area before assuming the pump motor itself has failed. Cleaning the filter takes just a few minutes and may save you an expensive repair.
How do I know if it's the wash pump or the drain pump that has failed?
The wash pump runs throughout the wash cycle to spray water. The drain pump only runs at the end of the cycle to remove water. F3 specifically points to the wash pump. F8 points to the drain pump.
Is it worth fixing a Whirlpool dishwasher with a failed wash pump?
It depends on the age and condition of the dishwasher. If it is under 7 years old and otherwise in good shape, repair is usually worth it. Wash pump replacement costs $150–$350 including labor. A new dishwasher starts around $400–$500.
