- SSharon ThomasSep 4, 2025
Check the cable and return sensor of your Wolf Boiler.
What to do if my Wolf CGB-75 return sensor is faulty?
Check the cable and return sensor of your Wolf Boiler.
What to do if my Wolf CGB-75 BCC is missing?
Fit the correct boiler coding card to your Wolf Boiler.
What to do if my Wolf CGB-75 Boiler shows incorrect BCC?
Fit the correct boiler coding card to your Wolf Boiler, as the current card is incompatible with the control unit PCB.
What to do if my Wolf Boiler has a flame failure during operation?
If the flame fails within 15 seconds after flame recognition, check the CO values and the ionization electrode and cable. Then, press the reset button.
How to fix TBV excess temperature in Wolf Boiler?
If the flow temperature has exceeded the limit for the TBV shutdown temperature, or if the heat exchanger is extremely dirty, or if the water pressure switch switches off at a pressure less than 1.0 bar, you should: * Check the system pressure. * Check the heating circuit pump. * Vent the system. * Press the reset button. * Clean the heat exchanger. * Check the TB combustion chamber. * Increase the system pressure. * Check the dirt filter.
What to do if my Wolf Boiler shows TW excess temperature?
If the flow/return temperature has exceeded the limit for the TW shutdown temperature, check the system pressure, vent the system, and set the pump to stage 2 or 3.
What to do if my Wolf Boiler indicates TBA excess temperature?
If there is overpressure in the flue gas system, clean the heat exchanger, check the flue gas system, and check the ventilation air.
Why does my Wolf Boiler show a faulty flow sensor?
The sensor for the flow temperature or the cable may be faulty, or the gas pressure may be less than the selected value at the gas governor (only displayed after 15 min). To resolve this, check the lead, flow sensor, gas pressure, and gas governor (accessory).
