Possible Causes
Defective heat pump assembly, Faulty temperature sensor in heat pump, Refrigerant leak (on true heat-pump systems), Wiring fault to heat pump
How to Fix / Troubleshooting
Safety first: Unplug the appliance. Heat-pump systems are complex and may contain refrigerant under pressure.
- Check basic heating: Confirm whether water heats at all during the wash. If completely cold and F15 appears, suspect the heat pump.
- Inspect wiring: Access the base and check the harness to the heat pump module for damage or loose connectors.
- Sensor testing: If accessible, test the NTC sensor integrated into the heat pump for correct resistance at room temperature.
- Professional service: Replacement of a heat pump or handling refrigerant circuits should be done by an authorized Bauknecht service technician.
