What does the Baxi Megaflo E650 fault code mean?
The E650 fault code on a Baxi Megaflo indicates a domestic hot water (DHW) system configuration fault. This typically suggests that there is an issue with the setup or communication between the boiler and the hot water system.
Common Causes
- Incorrect Configuration: The DHW system may not be set up correctly, leading to communication errors.
- Faulty Sensors: A malfunctioning temperature or flow sensor can disrupt the DHW operation and trigger the fault code.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as it involves the boiler’s configuration and potentially gas or electrical components that require professional handling.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an E650 fault could be around £150 to £250, depending on whether a sensor replacement or reconfiguration is necessary. This cost reflects the complexity of the issue and the need for professional expertise.
