Vokera Synergy fault E041
Fill the system
Gas boilerWhat it means
Water pressure fault requiring system fill, displayed with bar value, definitive alarm.
Likely causes
- System water pressure dropped below 0.3 bar safety threshold
- Low system water pressure
- System leak
- Frequent pressure loss may indicate system fault
Where to start
- Monitor for 10 minutes to see if pressure self-corrects or progresses to E040
- Monitor if fault persists after 10 min transitory period - if so E040 is displayed
- Check pressure value using hydrometer under shelf or INFO menu item I018

Safety: Isolate gas and power before you open the case. If you have been into the gas side, do a tightness test, and a combustion and flue check before you hand back. Gas Safe (UK) or RGI (Ireland) work only.
