How do I activate the boiler coding card on my Wolf CGB-50?
If the parameter plug must still be enabled on your Wolf Boiler, press the reset button twice.
What to do if Wolf CGB-50 Boiler flame fails during operation?
If your Wolf Boiler experiences flame failure within 15 seconds after flame recognition, check the CO values and inspect the ionization electrode and cable. Then, press the reset button.
Why does my Wolf CGB-50 show TBV excess temperature and low water pressure?
If your Wolf Boiler displays a TBV excess temperature and the water pressure is too low, check the system pressure and heating circuit pump. Also, check the HC pump step switch and vent the heating system. Press the reset button. Clean the heat exchanger and check the TB combustion chamber. Finally, increase system pressure.
What causes a gas fan fault in a Wolf Boiler?
If the gas fan in your Wolf Boiler doesn't reach the required pre-purging speed, ignition speed or doesn't stop, check the gas fan supply cable and the gas fan itself. Then, press the reset button.
How to resolve DHW excess temperature in Wolf Boiler?
If your Wolf Boiler shows a DHW excess temperature, check the system pressure and vent the heating system. Set the pump to stage 2 or 3.
What does CRC fault burner mean on my Wolf CGB-50 Boiler?
To address a CRC fault related to the burner in your Wolf Boiler, switch the power supply OFF and ON. If the problem persists, replace the control PCB.
What does CRC fault gas fried mean on my Wolf CGB-50 Boiler?
To address a CRC fault related to gas fried in your Wolf Boiler, switch the power supply OFF and ON. If the problem persists, replace the control PCB.
How to fix a gas valve '2' fault in a Wolf Boiler?
If your Wolf Boiler shows a gas valve „2“ fault, replace the gas combination valve.
Why is the ionization current dropping in my Wolf CGB-50 Boiler?
If the ionization current drops in your Wolf Boiler, it could be due to poor gas quality, a faulty monitoring electrode, or a severe storm. Check the monitoring electrode and lead.
