What to do if return sensor is faulty in my Wolf CGB-24?
If the return temperature sensor in your Wolf Boiler is faulty, meaning the return temperature sensor or lead is faulty, check the lead and replace the return sensor.
What to do if outside temp sensor is faulty in my Wolf CGB-24?
If the outside temperature sensor in your Wolf Boiler is faulty, meaning the outside temperature sensor or lead is faulty, check the lead and the outside temperature sensor.
What to do if my Wolf Boiler has no flame?
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 does CRC defaul values fault mean on my Wolf CGB-24 Boiler?
If your Wolf Boiler displays a CRC default values fault, it indicates that the EEPROM record "Master reset" is invalid. To resolve this, replace the control PCB.
What to do if the flow sensor is faulty in my Wolf CGB-24 Boiler?
If the flow sensor in your Wolf Boiler is faulty, meaning the flow temperature sensor or lead is faulty, check the lead and the flow sensor.
What does a CRC fault gas fired mean on a Wolf CGB-24?
If your Wolf Boiler displays a CRC fault gas fired, it indicates that the EEPROM record "Gas fried condensing boiler" is invalid. To resolve this, switch the power supply OFF and then ON again; if unsuccessful, replace the control PCB.
What to do if my Wolf Boiler has a fault in the 24 VAC supply?
If your Wolf Boiler indicates a fault in the 24 VAC supply, meaning the 24 V AC supply is outside the permissible range (e.g., short circuit), check the three-way valve and the gas fan.
What to do if my Wolf CGB-24 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-24?
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.
