What to do if Wolf COB shows flame pretence?
If your Wolf Boiler indicates flame pretence, meaning a flame is recognized before the burner starts, press the reset button. Also, check the solenoid valve for the oil pump.
What to do if the flue gas/ventilation air damper does not move in Wolf Boiler?
If the flue gas/ventilation air damper in your Wolf Boiler isn't moving, start by checking the flue gas/ventilation air damper and its wiring. The issue may be that the damper contact (E1) fails to close or open when there is a demand.
What to do if my Wolf COB fan does not stop?
If the fan in your Wolf Boiler isn't stopping, check the power cable to the fan and the fan itself. Then, press the reset button.
What to do if my Wolf Boiler shows TW excess temperature?
If your Wolf Boiler displays a TW excess temperature warning, it means the flow has exceeded the temperature limiter's limit of 100 °C. Vent the system and check the heating circuit pump.
What to do if my Wolf Boiler experiences flame failure during operation?
If your Wolf Boiler experiences flame failure during operation, it could be due to several reasons. Check the CO values and the flame monitor 2 and lead. Press the reset button. Inspect the flue system for leaks. Also, negative pressure at the oil pump might be too high, or flue gas recirculation might be occurring. Regular maintenance might be necessary.
What to do if my Wolf Boiler fan does not reach the set speed?
If the fan in your Wolf Boiler isn't reaching the set speed, the power cable to the fan should be checked. Also, check the fan itself. Ensure condensate can drain freely from the balanced flue system, and then press reset. Regular maintenance might be necessary.
Why does my Wolf Boiler have excess temperature (high limit safety cut-out)?
If your Wolf Boiler is experiencing excess temperature, triggering the high limit safety cut-out, it's likely because the flow temperature has exceeded 110 °C. Try testing the heating circuit pump, venting the system, pressing the reset button, and cleaning the heat exchanger.
What to do if my Wolf COB flue gas sensor shows excess temperature?
If the flue gas temperature in your Wolf Boiler exceeds 120 °C, try the following: Clean the heat exchanger and ensure all displacement devices are installed. Check the flow through the boiler and verify the boiler flow and return. Finally, press the reset button.
