Whirlpool Dishwasher Error Code F2

The F2 code means water has been detected in the anti-flood safety tray located underneath the dishwasher chassis. When this happens, the float switch LS6 triggers the control system to shut off the water inlet valve and run the drain pump to clear the tray. The dishwasher will not operate normally until the tray is dry and the water presence indicator returns to a low state. The root cause is almost always a water leak from somewhere inside the machine.

No, you should not attempt to run the dishwasher while the F2 code is active. The error indicates an active or recent water leak inside the appliance, and operating it could cause water damage to your floor or cabinetry. The dishwasher's safety system has already disabled the water inlet to prevent further leaking, and bypassing this condition before the leak is fixed is not recommended.

Repair costs vary widely depending on the cause. Replacing a door gasket is typically the least expensive fix, generally ranging from around 20 to 60 dollars for the part, while a new water inlet valve or pump component can cost between 40 and 150 dollars in parts. If a technician is needed for diagnosis and repair, labor charges can add 80 to 200 dollars or more depending on your location and the complexity of the repair.

Start by pulling the dishwasher out enough to inspect the anti-flood tray for standing water and identify where the water is coming from. Check the door gasket, internal hoses and clamps, and the inlet valve for signs of leaking. Also verify that the LS6 float moves freely and is not stuck in the raised position. Once the leak source is repaired and the tray is dry, the error should clear when the water presence indicator drops to its low state.

A simple reset will not permanently clear the F2 error if water remains in the anti-flood tray or if the underlying leak has not been repaired. The control system requires the water presence indicator (WI) to return to a low state before normal operation resumes. Even if a reset temporarily clears the display, the code will return once the machine attempts to fill with water again.
