What does the Baxi Platinum F23 fault code mean?
The F23 fault code on a Baxi Platinum boiler indicates a flame failure, meaning the boiler is unable to detect a flame during operation. This can prevent the boiler from functioning properly and may require immediate attention.
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 highly 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 due to the potential need for replacing the ignition electrode or clearing a blocked flue, which requires professional expertise.
