What does the Ideal Logic Plus F86 fault code mean?
The F86 fault code on the Ideal Logic Plus indicates a failure related to energy standards compliance, often linked to issues with the boiler’s efficiency or performance metrics. This fault typically requires attention to ensure the boiler operates within the required energy efficiency guidelines.
Common Causes
- Faulty Sensor: A malfunctioning sensor may fail to accurately measure energy output, triggering the F86 code.
- Internal Component Failure: Issues with internal components, such as the PCB or other electronic parts, can lead to incorrect readings and the subsequent fault code.
Can I fix it myself? (DIY)
Due to the complexity of the fault and potential safety risks, it is strongly advised to call a Gas Safe Engineer to diagnose and repair the issue rather than attempting DIY fixes.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F86 fault code is around £150 to £250, depending on whether a sensor replacement or PCB repair is needed. This estimate reflects the cost of parts and labour for a qualified engineer.
