What does the Baxi Platinum F97 fault code mean?
The F97 fault code on a Baxi Platinum boiler indicates a fault with the central heating (CH) flow switch sensor. This sensor is responsible for detecting the flow of water in the heating system, and a fault can prevent the boiler from operating correctly.
Common Causes
- Faulty Flow Switch: The flow switch may be malfunctioning or stuck, preventing it from accurately detecting water flow.
- Wiring Issues: Damaged or loose wiring connections to the flow switch can disrupt its operation and trigger the fault code.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that require professional handling. Attempting to fix it yourself could pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F97 fault code is around £150 to £250. This includes the cost of replacing the flow switch and any necessary labour charges.
