What does the Ideal Logic Max F43 fault code mean?
The F43 fault code on the Ideal Logic Max indicates a flue gas fault, which suggests that there is an issue with the flue system preventing proper venting of combustion gases. This can lead to unsafe operating conditions and requires immediate attention.
Common Causes
- Blocked Flue: A blockage in the flue can prevent exhaust gases from escaping, causing the boiler to shut down for safety.
- Flue Installation Issues: Incorrect installation or positioning of the flue can lead to improper venting and trigger the fault code.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer to address this issue, as it involves gas and safety regulations. Attempting to fix flue gas faults without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an F43 fault could range from £150 to £300, depending on whether the issue is a simple blockage or requires more extensive work on the flue system.
