What does the Baxi Platinum F71 fault code mean?
The F71 fault code on a Baxi Platinum boiler indicates that the central heating (CH) pressure is too high. This can lead to potential damage to the boiler and associated heating systems if not addressed promptly.
Common Causes
- Overfilled system: The system may have been overfilled during maintenance or topping up, causing excessive pressure.
- Faulty pressure relief valve: A malfunctioning pressure relief valve can fail to release excess pressure, leading to high readings.
Can I fix it myself? (DIY)
You can attempt to reduce the pressure by bleeding radiators to release excess water. However, if the issue persists or if you suspect a fault with the pressure relief valve, it is crucial to call a Gas Safe Engineer for further inspection and repair.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F71 fault could be around £150 to £250, depending on whether it involves simply bleeding the system or replacing a faulty pressure relief valve, which typically costs more due to parts and labour.
