Common Vaillant Faults We Repair in Mission
Vaillant reports problems through F-prefix fault codes (F.22, F.28…) shown on the control display. These are the faults our technicians diagnose most often on Mission service calls:
- F.28Ignition Failure at Start-Up
The boiler attempts to light and locks out — gas-supply issues, worn ignition electrodes, or a faulty gas valve. One reset is reasonable; repeats need diagnosis.
- F.29Flame Loss in Operation
Flame established then lost mid-cycle — electrode wear, condensate in the flue during cold weather, or gas-pressure fluctuation.
- F.22Low Water Pressure
System pressure below the operating threshold — repressurize to ~1.2–1.5 bar; recurring drops mean a leak or expansion-vessel fault.
- F.75Pump / Pressure-Sensor Fault
The control cannot verify pressure rise when the pump starts — a failing pump or a fouled pressure sensor.
- Electronics & Gas-Valve Control Faults
The F.61–F.64 family points at gas-valve control and board-level electronics — genuine diagnosis territory, not reset-and-hope.
