How to fix CRC error of burner in my Wolf Boiler?
If your Wolf Boiler shows a CRC error for the burner, switch the power supply off and on. If this does not resolve the issue, replace the controller PCB.
What to do if my Wolf Boiler shows DHW excess temperature?
If your Wolf Boiler displays a DHW excess temperature, check the system pressure and vent the system. You may also need to set the pump to stage 2 or 3.
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.
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 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.
Why is the LED constantly red on my Wolf CGB-75?
If your Wolf Boiler's LED is constantly red, this may be due to an ionisation cable short circuit or the ionisation electrode being earthed (casing). Check the ionisation cable and the position of the electrode to the burner. Press the reset button.
What to do if my Wolf Boiler has no flame established?
If your Wolf Boiler fails to establish a flame, check the gas supply line, opening the gas tap if necessary. Also, check the ignition electrode and ignition cable, then press the reset button.
What to do if my Wolf CGB-75 experiences flame failure during operation?
If your Wolf Boiler experiences flame failure during operation, check the CO2 values and the ionisation electrode and cable. Then, press the reset button.
Why does my Wolf CGB-75 Boiler start more than 20 times per hour?
If your Wolf Boiler shows burner starts more than 20 times per hour, check the flow rate. Ensure that the manifold sensor records the common flow temperature of the cascade.
