What does the Ideal Mini F98 fault code mean?
The F98 fault code on the Ideal Mini indicates a flow rate issue within the central heating system. This typically means that the boiler is not receiving adequate water flow, which can lead to overheating and potential damage.
Common Causes
- Blocked Filter: A blockage in the system filter can restrict water flow, causing the boiler to register a low flow rate.
- Pump Failure: If the circulation pump is malfunctioning or has failed, it may not be able to move water effectively through the system.
Can I fix it myself? (DIY)
While some issues may be resolved by checking and cleaning the system filter, it is highly recommended to call a Gas Safe Engineer for any gas or electrical-related problems to ensure safety and compliance with regulations.
Estimated Repair Cost (2026 UK Prices)
Repair costs for the F98 fault can range from £150 to £300, depending on whether the issue is a simple filter clean or a more complex pump replacement. A new pump installation typically costs around £250, including parts and labour.
