How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker without identifying the cause. Unplug the appliance before inspection.

  • Step 1 – Check for leaks: Inspect inside the cabinet for water leaks onto wiring, motor, or heater. Repair leaks as described in leak faults.
  • Step 2 – Insulation test (technician-level): Using an insulation tester (megger), check the wash heater and motor for leakage to earth. Replace any component with poor insulation.
  • Step 3 – Inspect mains filter and wiring: Look for burnt or damaged components on the mains filter and PCB. Replace damaged parts.
  • Step 4 – Professional service: Because of the shock risk, earth leakage faults are best fully diagnosed and repaired by a qualified electrician or appliance technician.
