What does the Baxi Megaflo E460 fault code mean?
The E460 fault code on a Baxi Megaflo indicates a problem with the central heating (CH) return temperature. This typically means that the return water temperature is outside the expected range, which can affect the boiler’s efficiency and performance.
Common Causes
- Blocked Heat Exchanger: A blockage can prevent proper water flow, leading to incorrect temperature readings.
- Faulty Temperature Sensor: If the sensor is malfunctioning, it may inaccurately report the return temperature, triggering 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 be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the E460 fault could be around £150 to £250, depending on whether a temperature sensor replacement or heat exchanger cleaning is needed. This cost reflects the typical labour and parts required for such repairs.
