Washer stops and displays F07, may not heat water properly or may abort cycle

Safety first: Unplug the washer and shut off water supply. Heating components can retain heat; allow time to cool.

Step-by-step checks:

• 1. Access heater assembly: Remove the rear panel. The heater is usually mounted in the bottom of the outer tub with two terminals and a ground connection.
• 2. Inspect wiring: Check the heater wires and connectors for burns, discoloration, or looseness. Reseat connectors firmly.
• 3. Test heater resistance: Disconnect the heater wires and measure resistance across the heater terminals. Typical values are 10–30 Ω (check model specs). An open circuit means the heater is failed.
• 4. Check for ground fault: Measure from each heater terminal to the metal tub or ground. Any continuity indicates a shorted heater that must be replaced.
• 5. Control relay check: If the heater tests good, inspect the main control board for a burned heater relay (darkened area, melted plastic). A failed relay requires board replacement.
• 6. Replace faulty parts: Replace the heater with the correct Admiral-compatible element and new gasket. Tighten the mounting nut evenly to prevent leaks.

When to call a technician: If the heater and wiring are good but F07 persists, the control board or temperature sensing circuit may need professional evaluation.
