Whirlpool Washer Error Code F33

F33 on a Whirlpool washer is a door switch error. It triggers when the door has not been opened for three consecutive cycles, or when the door switch reads as open while the door lock is engaged for more than five seconds. The washer stops operation until the condition is resolved to prevent running with an unconfirmed door status.

A basic power reset alone may not permanently clear F33 if there is an underlying hardware problem. The recommended first step is to open and close the door while the machine is powered on, which directly addresses the door switch condition the code monitors. If the fault is caused by a failed latch or wiring issue, the code will return after a reset until the hardware is repaired.

If the fix is as simple as opening and closing the door, there is no cost involved. If a door latch assembly replacement is needed, parts typically range from $20 to $80 depending on the model, plus labor if a technician is involved. A main control board replacement, if required, is the most expensive scenario and can range from $150 to $400 or more for parts and labor combined.

Start by powering on the washer, fully opening the door, and then closing it again. This resets the latch and switch signal and will clear the code if the error was triggered by the consecutive-cycle condition. If the error returns, inspect the door latch assembly and the wiring harness connecting it to the control board, as these are the most common hardware causes.

F33 indicates the washer cannot confirm the door is properly secured, so the machine will typically not run a cycle while the code is active. You should not attempt to force the machine to operate in this state. Address the door switch condition before resuming normal use to avoid water leakage or injury from an unsecured door.
