The Water Pressure Sensor on Your Viessmann Boiler

The water pressure sensor (transducer) tells the boiler the system pressure so it can lock out safely on low pressure and display fill prompts. A drifting sensor causes false low-pressure faults even when pressure is fine.

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