How to Fix / Troubleshooting

Safety first: Unplug the appliance. If you suspect electrical supply issues, consult a qualified electrician.

  • Step 1 – Check mains supply: Verify that the outlet provides stable voltage and that no extension cords or adapters are overheating.
  • Step 2 – Inspect power connections: Remove the rear and top panels and check the main power terminal block for loose screws or burnt contacts. Tighten or replace as needed.
  • Step 3 – Motor inspection: Follow the steps under E07 to inspect the motor and wiring for shorts or damage.
