Washer shows F05 or F5, may not start or may stop mid-cycle, often associated with door not locking or unlocking properly.

Safety first: Unplug the washer before working around the door lock area. Do not force the door open with tools that could damage the seal or glass.

Step-by-step:

• Check door closure: Ensure the door closes fully and the latch engages. Look for clothing or foreign objects caught between the door and the gasket.
• Inspect door strike: Examine the plastic door strike on the door for cracks or missing pieces. Replace if damaged.
• Listen for lock operation: When starting a cycle (with power connected), you should hear the door lock click. If there is no sound, the lock may not be receiving power or is failed.
• Access door lock: Unplug the washer. Remove the front panel or the door gasket clamp (depending on model) to access the door lock assembly mounted to the front panel.
• Check wiring: Inspect the harness to the door lock for loose connectors, broken wires, or burn marks. Reseat connectors firmly.
• Test door lock: With the lock removed, test the lock’s internal switches and coil for continuity according to the tech sheet. An open circuit where continuity is expected indicates a bad lock.
• Replace door lock assembly: If testing confirms failure, install a new Whirlpool door lock assembly specific to your model. Reinstall the gasket and clamp carefully to avoid leaks.

When to call a technician: If the door remains locked with clothes inside and you cannot access the manual release, or if you are not comfortable removing the front panel or gasket, contact a professional.
