Possible Causes
Blocked evaporator or condenser coil, Failed heat pump compressor, Faulty heat pump fan motor, Refrigerant leak in sealed system
How to Fix / Troubleshooting
Safety first: Disconnect the dryer from the mains. Heat pump systems contain high-pressure refrigerant; sealed system work must be done by qualified personnel.
- Clean filters and condenser: Remove and clean all lint filters. If the model has a user-accessible heat exchanger, remove and rinse it thoroughly.
- Check airflow: Ensure that intake and exhaust vents on the cabinet are not blocked. Clean any dust build-up around the heat pump compartment.
- Listen for compressor and fan: During a test run (after reassembly and reconnecting power), listen for the compressor and fan operation. If either does not run, further electrical diagnosis is required.
- Do not open sealed system: If E12 persists after cleaning and basic checks, contact a qualified refrigeration technician to inspect the compressor, refrigerant charge, and sealed system components.
