Vokera Synergy fault E092
Calibration failed, excessive number of calibrations within the hour
Gas boilerWhat it means
Calibration failed due to excessive calibration attempts within one hour, definitive alarm.
Likely causes
- Excessive number of calibration attempts within the hour
- 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.
