What does the Vaillant ecoTEC exclusive F67 fault code mean?
The F67 fault code indicates a problem with the air intake system of the Vaillant ecoTEC exclusive boiler. This typically means that the boiler is unable to draw in the necessary air for combustion, which can lead to inefficient operation or shutdown.
Common Causes
- Blocked Air Intake: Debris, dust, or obstructions may be blocking the air intake, preventing proper airflow.
- Faulty Air Pressure Switch: The air pressure switch may be malfunctioning, failing to detect the correct air pressure levels needed for operation.
Can I fix it myself? (DIY)
While you can check for visible blockages in the air intake, it is strongly advised to call a Gas Safe Engineer for any repairs or if the issue persists, as it may involve gas or electrical components that require professional handling.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F67 fault could range from £150 to £300, depending on whether the issue is a simple blockage or requires replacement of the air pressure switch.
