What to do if my Viessmann Vitodens 050-W BP JD Boiler burner stops below the set water temperature and restarts immediately?
If the burner stops below the set boiler water temperature and restarts immediately, check the flue system for tightness to prevent flue gas recirculation. Also, check the gas flow pressure.
What to do if my Viessmann Vitodens 050-W BP JD displays fault code 52?
If fault code 52 is displayed, which indicates a short circuit in the flow sensor, check the connections and lead. If necessary, replace the sensor.
What to do if my Viessmann Boiler displays fault code 51?
If your Viessmann Boiler displays fault code 51, indicating a short circuit in the outlet temperature sensor, check the sensor.
What to do if my Viessmann Vitodens 050-W BP JD Boiler displays fault code 38?
If fault code 38 is displayed on your Viessmann Boiler, it indicates a lead break in the boiler water temperature sensor. Check the boiler water temperature sensor.
What to do if my Viessmann Vitodens 050-W BP JD Boiler displays fault code 30?
If your Viessmann Boiler shows fault code 30, which means there's a short circuit in the boiler water temperature sensor, check the boiler water temperature sensor.
What to do if my Viessmann Vitodens 050-W BP JD Boiler displays fault code 18?
If your Viessmann Boiler displays fault code 18, which indicates a lead break in the outside temperature sensor, check the outside temperature sensor and lead.
What to do if my Viessmann Vitodens 050-W BP JD displays fault code 10?
If your Viessmann Boiler displays fault code 10, indicating a short circuit in the outside temperature sensor, check the outside temperature sensor and lead.
What to do if my Viessmann Boiler displays fault F4 due to gas train issues?
If your Viessmann Boiler displays fault F4 and the cause is related to the gas train opening, check the gas train for the correct control voltage (230 V) and verify the gas supply pressure.
What to do if my Viessmann Vitodens 050-W BP JD Boiler displays fault F4 related to ignition?
If your Viessmann Boiler displays fault F4, and it's related to ignition, check the ignition module connection.
