How to clear errors in fault memory of Viessmann VITOCROSSAL 200 Boiler?
To reset the Viessmann Boiler burner control unit and clear errors displayed in the fault memory, hold down the reset button R for longer than 0.5 seconds. The operating display will then reappear.
What should I do if my Viessmann VITOCROSSAL 200 Boiler displays error code F 89?
If your Viessmann Boiler is displaying the error code F 89, it indicates a lead break in the flue gas temperature sensor (A or B) or burner control unit. Check the lead and sensors (A and B), and replace the sensor if required.
Why is my Viessmann VITOCROSSAL 200 showing error F 83?
If your Viessmann Boiler shows error code F 83, this indicates a sensor drift in the flue gas temperature sensor (A or B) or burner control unit. Check the lead and sensors (A and B), and replace the sensor if required.
What does F 81 error mean on my Viessmann VITOCROSSAL 200 and how can I resolve it?
If your Viessmann Boiler displays error code F 81, it means there's a sensor drift in the boiler water temperature sensor or burner control unit. Check the lead and dual sensor; replace the sensor if required.
What causes error code F 88 on a Viessmann VITOCROSSAL 200 Boiler?
If your Viessmann Boiler displays the error code F 88, it indicates a lead break in the boiler water temperature sensor or burner control unit. Check the lead and dual sensor; replace the sensor if required.
How to fix Viessmann VITOCROSSAL 200 Boiler error F 82?
If your Viessmann Boiler is showing the error code F 82, there may be a short circuit in the flue gas temperature sensor (A or B) or the burner control unit. Check the lead and sensors (A and B), and replace the sensor if needed.
What does error code F 80 mean on my Viessmann VITOCROSSAL 200 Boiler?
If your Viessmann Boiler shows the error code F 80, it indicates a potential short circuit in the boiler water temperature sensor or burner control unit. Check the lead and dual sensor, and replace the sensor if necessary.
Why does my Viessmann VITOCROSSAL 200 Boiler display F b7 error if the coding card doesn't match the burner control unit?
If your Viessmann Boiler displays error code F b7, it may be because the coding card does not match the burner control unit. Replace the coding card or burner control unit. Important: Ensure the power is off before replacing the coding card.
What to do if my Viessmann VITOCROSSAL 200 shows F b7 error?
If your Viessmann Boiler displays error code F b7, it might be due to a missing, incorrect, or faulty coding card in the burner control unit. First, ensure the coding card is properly inserted. If it is, check the card for any damage or inconsistencies. If problems persist, consider replacing the coding card.
