Vokera Synergy fault E095
Calibration failed
Gas boilerWhat it means
Calibration failed, transitory alarm.
Likely causes
- Flue components incorrectly assembled, fixed or supported
- Flue or flue terminal obstructed
- Degraded seals around appliance burner, internal flue, door or case
- Maximum flue lengths exceeded or guidance (e.g. Technical Bulletin 008) not followed
- Analyser not zeroed/calibrated correctly before use
Where to start
- Loosen screws holding ignition/detection electrode and remove it
- Remove burner insulating panel by inserting a blade just under the surface
- Remove any residual fixing adhesive

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.
