How to Fix / Troubleshooting
Safety first: Disconnect mains power before any work. Heat pump and refrigerant components must only be serviced by qualified technicians.
Owner maintenance:
- Clean filters and heat exchanger: Remove and clean the lint filter and any secondary filters. If the heat exchanger is user-accessible, clean it carefully with a soft brush and water.
- Ensure ventilation: Make sure the dryer has adequate space around it and that intake/exhaust grilles are not blocked.
Technical checks (for service personnel):
- Test the heat pump NTC sensors for correct resistance.
- Check refrigerant pressures and system integrity.
- Verify operation of the heat pump control module.
Resolution: Replace faulty sensors or repair the sealed system as required. This is not a DIY repair.
