How to Fix / Troubleshooting

Safety first: Unplug the dryer before accessing electrical components. If you suspect household wiring issues, consult a qualified electrician.

  • Check plug and socket: Ensure the plug is fully inserted and the socket is not loose. Try a different socket if possible.
  • Inspect mains filter and wiring: Access the mains filter and check all spade connectors for tightness and signs of overheating. Replace the filter if damaged.
  • Examine control board capacitors: Look for bulging or leaking capacitors on the control board. If present, the board should be replaced.
