Washer displays F36 and may not start, often associated with door lock circuit

Safety first: Unplug the washer before inspecting the lock or control.

Step-by-step checks:

• 1. Inspect lock and wiring: Access the door lock and check for signs of overheating, melted plastic, or moisture. Dry the area if wet.
• 2. Check harness: Look for rubbed-through insulation or wires touching metal. Repair or replace damaged sections.
• 3. Test lock resistance: Measure resistance across lock coils. A very low reading (near short) indicates a failed lock.
• 4. Replace lock if shorted: Install a new door lock assembly and retest.

When to call a technician: If the lock and wiring are good, the control's lock driver circuit may be damaged and require board replacement.
