What does the Baxi EcoBlue F22 fault code mean?
The F22 fault code on a Baxi EcoBlue boiler indicates a dry fire condition or low water pressure in the system. This typically means that the boiler is unable to detect sufficient water flow, which can lead to overheating and potential damage.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system or insufficient water supply, preventing the boiler from operating correctly.
- Blocked or Faulty Pressure Sensor: A malfunctioning pressure sensor may incorrectly report low pressure, causing the boiler to shut down.
Can I fix it myself? (DIY)
If you are comfortable, you can check the pressure gauge on your boiler; it should typically be between 1-1.5 bar. If it’s below this, you can re-pressurise the system using the filling loop. However, if you suspect any gas or electrical issues, it is crucial to call a Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F22 fault could range around £150-£250, primarily for re-pressurising the system or replacing a faulty pressure sensor. This cost reflects the typical labour and parts required for such repairs.
