What does the Baxi Platinum F67 fault code mean?
The F67 fault code on a Baxi Platinum boiler indicates that the central heating (CH) flow rate is too high. This can lead to potential overheating and may affect the efficiency and safety of the boiler.
Common Causes
- Incorrect Pump Speed: The pump may be set to a speed that is too high for the system, causing excessive flow rates.
- Blocked or Closed Valves: Valves in the heating system may be partially closed or blocked, leading to an imbalance in flow rates.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and resolve this issue, as it may involve adjustments to the pump or system components that require professional expertise.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F67 fault could be around £150 to £250, depending on whether the pump needs adjustment or replacement. This cost reflects the complexity of the work and the need for a qualified technician.
