What does the Baxi EcoBlue F23 fault code mean?
The F23 fault code on a Baxi EcoBlue boiler indicates a flame failure, meaning the boiler is unable to detect a flame during operation. This can prevent the boiler from heating water or providing central heating.
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 malfunctioning, it may not ignite the gas properly, causing the flame to fail.
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 a F23 fault could be around £150 to £250, primarily depending on whether the ignition electrode needs replacement or if the flue requires clearing.
