Dryer shows E12 and may not heat correctly; often on heat pump models.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the dryer. Heat pump systems are sealed and contain refrigerant; do not open the sealed circuit yourself.
User-level checks:
- Clean filters and heat exchanger: Remove and clean all lint filters and the lower heat exchanger/condenser thoroughly.
- Check fans: Listen for internal fans running when the dryer is operating. If a fan is not running, airflow and heat pump performance will be affected.
Professional service: If E12 persists after cleaning and basic checks, the issue may involve the compressor, refrigerant charge, or pressure sensors. These require specialized tools and must be handled by a certified refrigeration technician or Candy service center.
