What does the Ideal Logic Plus F98 fault code mean?
The F98 fault code on the Ideal Logic Plus indicates a problem with the boiler’s energy trends, which can affect its efficiency and performance. This issue typically arises from a malfunction in the boiler’s internal sensors or control systems.
Common Causes
- Faulty Sensor: A malfunctioning temperature or pressure sensor can lead to inaccurate readings, triggering the F98 fault code.
- Control Board Issue: Problems with the control board can disrupt the communication between components, causing the energy trends to be reported incorrectly.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair the F98 fault, as it involves complex electrical and gas components that require professional expertise.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the F98 fault could range around £150 to £300, primarily depending on whether a sensor replacement or control board repair is necessary, as these components can be costly and require skilled labour.
