What does the Baxi Platinum F65 fault code mean?
The F65 fault code on a Baxi Platinum boiler indicates that the central heating (CH) flow rate is too low, which can prevent the boiler from operating efficiently. This issue may lead to inadequate heating and could potentially cause further damage if not addressed promptly.
Common Causes
- Blocked Filters: A blockage in the system filters can restrict water flow, leading to low flow rates.
- Pump Failure: If the circulation pump is malfunctioning or has failed, it may not be able to circulate water effectively through the heating system.
Can I fix it myself? (DIY)
While you can check and clean filters, it is strongly advised to call a Gas Safe Engineer for any issues related to the pump or gas components to ensure safety and compliance with regulations.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F65 fault could range from £150 to £300, primarily depending on whether the issue is a simple filter clean or requires a pump replacement, which can be more costly.
