What does the Baxi Platinum F24 fault code mean?
The F24 fault code on a Baxi Platinum boiler indicates an overheating issue, which can lead to potential damage if not addressed promptly. This fault typically arises when the boiler’s temperature exceeds safe operational limits, triggering a safety mechanism to prevent further overheating.
Common Causes
- Blocked Heat Exchanger: A buildup of debris or limescale can restrict water flow, causing the boiler to overheat.
- Faulty Thermostat: If the thermostat is malfunctioning, it may not accurately read the temperature, leading to overheating conditions.
Can I fix it myself? (DIY)
While some basic maintenance can be performed, it is strongly advised to call a Gas Safe Engineer for any issues related to overheating, as they can involve gas and electrical components that require professional handling.
Estimated Repair Cost (2026 UK Prices)
