What Does Error F03 Mean?

The Whirlpool Washer Dryer F03 error code indicates a malfunction in the door lock mechanism, often linked to a faulty temperature sensor (NTC) or issues with water drainage and level sensing. Symptoms include the washer stopping mid-cycle, failure to advance from wash to rinse, and potential display of combined error codes. Addressing the F03 error may involve checking the door lock, inspecting the water drainage system, or testing the temperature sensor.

Common Symptoms:

  • Washer stops mid‑cycle showing F03
  • May fail to advance from wash to rinse
  • Machine may display combined codes (e.g., E01 F03)
  • Water may not drain properly or water level sensing issues

Possible Causes

  • Faulty water temperature sensor (NTC) (medium)
  • Water level/pressure sensing or drainage system fault (medium)

How to Fix Error F03

DIY Fix Basic checks and resets

  1. Power off and unplug the unit for 5 minutes then restart
  2. Ensure drain hose is not kinked or blocked
  3. Verify water supply hoses are connected and valves fully open
  4. Check for combined codes (e.g., E01 F03) which often indicate water level issues

Technician Only Diagnostic inspection and component testing

  1. Test temperature sensor (NTC) resistance variation with a multimeter and inspect wiring harness
  2. Inspect pressure switch, air hose, and air trap for blockage or leaks
  3. Check drain pump and impeller for blockage or failure
  4. Inspect control board for signs of damage if sensors and wiring test OK

Parts needed: Temperature sensor (NTC), Pressure switch/air hose, Drain pump and impeller, Main control board
