What does the Baxi Megaflo E125 fault code mean?
The E125 fault code on a Baxi Megaflo boiler indicates a flame failure, meaning the boiler is unable to detect a flame during the ignition process. This can prevent the boiler from heating water and may require troubleshooting to identify the underlying issue.
Common Causes
- Blocked Flue: A blockage in the flue can prevent proper ventilation, leading to flame failure.
- Faulty Ignition Electrode: If the ignition electrode is damaged or dirty, it may not create a spark to ignite the gas.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any gas or electrical issues, as working on these systems can be dangerous. However, you can check the boiler pressure and reset the boiler if necessary.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E125 fault could range from £150 to £300, depending on whether the issue is a simple flue blockage or requires replacement of the ignition electrode, which typically costs around £100 to £200.
