What does the Baxi Platinum F28 fault code mean?
The F28 fault code on a Baxi Platinum boiler indicates that the appliance has failed to detect a flame during operation. This can prevent the boiler from heating water and providing central heating.
Common Causes
- Gas Supply Issue: There may be a problem with the gas supply, such as a closed valve or an interruption in the gas line.
- Ignition Electrode Fault: The ignition electrode may be dirty or faulty, preventing it from creating a spark to ignite the gas.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any gas-related issues, as working with gas can be dangerous. However, you can check if the gas supply is on and ensure that the boiler’s pressure is within the recommended range.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F28 fault could be around £150 to £250, depending on whether the issue is with the gas supply or requires replacement of the ignition electrode.
