What does the Baxi Megaflo E133 fault code mean?
The E133 fault code on a Baxi Megaflo indicates that the boiler has failed to detect a flame during operation. This can prevent the boiler from heating water and may require immediate attention to restore functionality.
Common Causes
- Faulty Ignition Electrode: If the ignition electrode is damaged or dirty, it may fail to create a spark to ignite the gas.
- Gas Supply Issues: Insufficient gas pressure or a blockage in the gas supply line can prevent the boiler from igniting properly.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any issues related to gas or electrical components. Attempting to fix these problems without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the E133 fault could range from £150 to £300, depending on whether the ignition electrode needs replacing or if there are gas supply issues that require more extensive work.
