Whirlpool Washer Error Code F03

F03 means the washer's drain cycle exceeded the 4-minute timeout before the pressure sensor detected an empty tub. The control board monitors drain progress through the pressure sensor, and when the empty level is not reached in time, it stops the cycle and displays this code. It points to a problem in the drain path, the drain pump, or the water level sensing system.

You should not continue running full wash cycles with water in the tub until the drain issue is resolved. If water cannot exit the machine, running additional cycles risks overflow or leaving clothes sitting in standing water for extended periods. It is safe to press START once to attempt completion of the drain, but persistent F03 faults should be diagnosed before resuming normal use.

If the fix involves clearing a kinked hose or cleaning the pump filter, there is no parts cost and only your time is involved. Replacing a drain pump typically costs between $50 and $150 for the part, plus labor if you hire a technician, bringing the total repair to roughly $100 to $300 depending on your area and service rates. A pressure sensor replacement is generally less expensive than a pump.

Many F03 causes are DIY-friendly. Start by pressing START to allow the cycle to continue, then check the drain hose for kinks or clogs and clean the drain pump filter if your model has an accessible one. If the hose and filter are clear, further diagnosis of the pump or pressure sensor may require a multimeter and some disassembly, which is manageable for a mechanically inclined homeowner.

Resetting the washer may clear the displayed code temporarily, but it will return as soon as the drain system fails to empty within 4 minutes again. The underlying cause, such as a clog, kink, or faulty component, must be corrected for the error to stay gone. A reset is useful for testing after a repair but is not a fix on its own.
