How to fix CRC error of default values in my Wolf Boiler?
If your Wolf Boiler shows a CRC error with default values, replace the control unit PCB.
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.
How to fix CRC fault in my Wolf gas condensing Boiler?
If your Wolf Boiler shows a CRC fault for the gas condensing boiler, switch the power supply off and on. If the issue persists, replace the controller PCB.
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).
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.
What to do if my Wolf Boiler's cylinder sensor is faulty?
If the DHW temperature sensor or lead is faulty, check the sensor and the lead.
What to do if my Wolf Boiler shows a CRC fault, BCC?
If there is a faulty boiler coding card, replace it.
What to do if my Wolf CGB-75 shows a faulty flow sensor or low gas pressure?
If your Wolf Boiler has a faulty flow sensor or indicates that the gas pressure is too low, check the cable and flow sensor. Also, check the gas pressure and gas governor.
How to fix ionisation current fluctuation in my Wolf CGB-75 Boiler?
If your Wolf Boiler is experiencing ionisation current fluctuation, clean the trap, check the flue system and ventilation air, and check the monitoring electrode.
What to do if my Wolf CGB-75 shows TBA excess temperature and excess pressure in the flue system?
If your Wolf Boiler displays TBA excess temperature or excess pressure in the flue system, clean the heat exchanger, check the flue system, and check the ventilation air.
