Possible Causes
Faulty compressor, Faulty heat pump fan, Refrigerant leak or low charge, Faulty heat pump temperature or pressure sensor
How to Fix / Troubleshooting
Safety first: Unplug the dryer. Heat pump systems are sealed and contain refrigerant; only certified technicians should open the sealed circuit.
- Basic airflow checks: Ensure all filters and the condenser are clean and that intake and exhaust grilles are unobstructed. Poor airflow can trigger heat pump errors.
- Listen for compressor: When starting a cycle, listen for the compressor running after a short delay. If it never starts, there may be an electrical or compressor fault.
- Check fans: Verify that internal fans are running when the machine is heating. If not, inspect and replace faulty fans.
- Do not attempt refrigerant repairs: If E13 persists, contact a Hoover-authorized service center. Compressor, refrigerant, and pressure sensor issues require specialist tools and must comply with environmental regulations.
