Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the dryer. Heat pump systems contain high-pressure refrigerant and high-voltage electronics; only qualified personnel should work on sealed system components.
User-level checks:
- Clean all filters and the heat exchanger to ensure good airflow.
- Verify that the ambient temperature is within the operating range specified by Indesit.
Technical checks (for professionals):
- Measure compressor winding resistances and insulation resistance.
- Check the inverter module for power supply and error indications.
- Inspect wiring and connectors between compressor, inverter, and main PCB.
Resolution: F14 typically requires replacement of the compressor, inverter module, or both. This should be performed by an authorized Indesit service technician due to refrigerant handling and safety regulations.
