If no flame is established during the burner start in your Wolf Boiler, check the gas supply pipe and open the gas shut-off valve if needed. Also, inspect the ignition electrode and cable. Finally, press the reset button.
What to do if my Wolf Boiler shows a flame pretence error?
If your Wolf Boiler indicates a flame pretence error, meaning a flame is recognized before the burner starts, press the reset button.
What does a CRC fault burner mean on a Wolf CGB-K-24 Boiler?
If your Wolf Boiler displays a CRC fault burner, it indicates that the EEPROM record "Boiler" is invalid. To resolve this, switch the power supply OFF and then ON again. If the issue persists, replace the control PCB.
What to do if my Wolf CGB-K-24 gas fan does not reach the ignition speed?
If the gas fan in your Wolf Boiler does not reach the ignition speed, check the gas fan supply cable and the gas fan. Then, press the reset button.
What to do if my Wolf CGB-K-24 gas fan does not reach the required pre-purging speed?
If the gas fan in your Wolf Boiler does not reach the required pre-purging speed, check the gas fan supply cable and the gas fan. Then, press the reset button.
What causes TBA excess temp. in Wolf CGB-K-24 Boiler?
If your Wolf Boiler is showing TBA excess temp, it means that the flue gas temperature has exceeded the limit for TBA shutdown. Check for correct installation of the combustion chamber pot.
What to do if my Wolf CGB-K-24 gas fan doesn't stop?
If the gas fan in your Wolf Boiler does not stop, check the gas fan supply cable and the gas fan itself. After checking, press the reset button.
What to do if my Wolf Boiler shows TW excess temperature?
If your Wolf Boiler displays a TW excess temperature error, indicating that the flow/return temperature has exceeded the limit for TW shutdown, check the system pressure and vent the heating system. Additionally, set the pump to stage 2 or 3.
How to fix TBV excess temperature on Wolf CGB-K-24 Boiler?
If your Wolf Boiler shows a TBV excess temperature error, it means the flow temperature has exceeded the limit for TBV shutdown, possibly due to a severely contaminated heat exchanger. To resolve this, check the system pressure and heating circuit pump. Also, check the HC pump step switch, vent the heating system, and then press the reset button.
