The Flame Sensor on Your Viessmann Boiler

The flame sensor (flame-rectification probe) confirms a flame is actually burning. If it cannot detect flame, the control shuts the gas off within seconds. A dirty or failed sensor causes the boiler to light then drop out repeatedly.

On Viessmann systems — including models such as Vitodens 100-W, Vitodens 200-W, Vitodens 050-W — a failing flame sensor often shows up as f2 no flame or related symptoms. We diagnose it precisely and install the correct genuine Viessmann part.
