Fault
code
Warning Possible causes Remedy
54 GLV actuators Flue gas recirculation
Incorrect gas type setting
Incorrect gas restrictor
Gas valve faulty
Fan faulty
Flue gas recirculation:
- Check the flue path inside and outside the
appliance (leaking, blocked).
- Check wind effect.
Gas type setting
- Check gas type setting on the gas valve and
the AM/BM.
Gas restrictor:
- Remove the gas valve retainer.
- Check that the correct gas restrictor is fitted.
CGB-2-20/24: blue
CGB-2-14: black
Gas valve:
- Check cables, plugs, power supply and
switching; if valves faulty, replace as neces-
sary.
Fan:
- Check for bearing damage.
- Check cables, plug-in connections, power
supply and switching.
- If fan faulty, replace it.
55 GLV system error Internal plausibility check of GBC-e
failed.
System error:
- Check for a strong electromagnetic field
nearby.
- Switch power ON/OFF, reset if necessary.
Press reset button.
58 Timeout calibration The heating appliance cannot carry out
calibration
Flue gas recirculation
Fan faulty
Inadequate heat transfer
Flue gas recirculation:
- Check the flue path inside and outside the
appliance (leaking, blocked).
Fan:
- Check that the fan and its wiring are intact.
Inadequate heat transfer:
- Ensure adequate heat transfer.
Check IO electrode
Press reset button.
68 GPV offset Inadmissible GPV curves (offset)
Corrupt/incorrect EEProm value
Gas valve faulty
Corrupt EEProm value:
- Replace boiler coding card.
- Check leads and plug-in connections.
- If OK and no function, replace the gas valve.
69 Adaptation not possible Fan faulty (no stable state at minimum
output)
Strong wind effect
Wind:
