Vokera Pinnacle System 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. Must be corrected within 10 minutes or it becomes a definitive fault (E040).
Likely causes
- System pressure too low
- Water leak in heating system
- System pressure outside optimal range of 1.0-1.5 bar
- System water pressure drop below required minimum value
Where to start
- Check system pressure
- Check system water pressure against minimum required value
- Check Water pressure reading for system pressure verification
