How to Fix / Troubleshooting

Safety: Do not repeatedly reset a tripping breaker without finding the cause. Unplug the appliance before testing.

  • Isolate when it trips:
    • Note at which stage (fill, heat, spin, dry) the trip occurs to narrow down the suspect component.
  • Test heater to earth:
    • Disconnect heater wires.
    • Measure resistance between each terminal and earth; any continuity indicates a fault.
  • Inspect motor and wiring:
    • Check for chafed wires touching the metal cabinet.
    • Test motor windings to earth for leakage.
  • Check mains filter: Inspect for cracks or burning; replace if suspect.
