What to do if my Viessmann Vitotron 100 does not heat?
- NnicolebaileySep 12, 2025
If your Viessmann Boiler does not heat, it could be due to a failure of the cylinder temperature sensor or the control panel. Contact an authorized service person for replacement of the cylinder temperature sensor or thermostat, or if there is a failure of the control panel.
