What does the Ideal Mini F41 fault code mean?
The F41 fault code on the Ideal Mini indicates a problem with the central heating flow switch, which is responsible for detecting the flow of water through the heating system. This fault can prevent the boiler from operating correctly, leading to heating issues.
Common Causes
- Faulty Flow Switch: The flow switch may be defective or stuck, preventing it from accurately detecting water flow.
- Blocked System: A blockage in the heating system can restrict water flow, causing the flow switch to fail to operate properly.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair this issue, as it involves gas and electrical components that can be dangerous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for the F41 fault code is around £150 to £250, which includes the replacement of the flow switch and any necessary labour. This cost reflects the complexity of the repair and the need for a qualified engineer.
