How to Fix / Troubleshooting

Safety first: Unplug the washer before internal inspection.

  • Step 1 – Check external power: Ensure the plug fits tightly in the socket and that there are no intermittent power cuts.
  • Step 2 – Door lock: Inspect and, if necessary, replace the door lock if the machine stops when bumped or during spin.
  • Step 3 – Internal wiring: Remove the top cover and gently tug on harness connectors to ensure they are secure. Reseat any loose plugs.
  • Step 4 – Overheating: If the machine stops after long runs and restarts after cooling, the motor or PCB may be overheating and should be checked by a technician.
