Vokera Pinnacle Combi fault E041
Low water pressure (temporary fault)
Gas boilerWhat it means
Temporary fault indicating the boiler is not working properly due to low water pressure. Operation required within 10 minutes of message appearing, otherwise the anomaly becomes definitive (E040).
Likely causes
- System water pressure dropped significantly
- Water leak in heating system
- Failure to top up system after FIL warning
Where to start
- Check system pressure on LCD display or gauge on underside of appliance
- Check pressure transducer operation if burner/pump/fan de-activate on low pressure
- Check water pressure transducer (service)
