What does the Baxi Platinum F80 fault code mean?
The F80 fault code on a Baxi Platinum boiler indicates that the domestic hot water (DHW) supply temperature is excessively high. This can lead to potential safety issues and requires immediate attention to prevent scalding or damage to the system.
Common Causes
- Faulty Temperature Sensor: A malfunctioning temperature sensor may incorrectly read the water temperature, causing the boiler to overheat the water.
- Incorrect Boiler Settings: If the temperature settings on the boiler are set too high, it can result in the DHW supply temperature exceeding safe limits.
Can I fix it myself? (DIY)
It is advisable 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 addressing the F80 fault code could be around £150 to £250, primarily depending on whether the temperature sensor needs replacing or if adjustments to the settings are required. This cost reflects the typical labour and parts involved in such repairs.
