What does the Ideal Logic Max F58 fault code mean?
The F58 fault code on the Ideal Logic Max indicates that the central heating (CH) flow switch is open, which means the boiler is not detecting the flow of water through the heating system. This can prevent the boiler from operating correctly, leading to heating issues.
Common Causes
- Blocked or Dirty Flow Switch: A buildup of debris or scale can prevent the flow switch from operating properly.
- Wiring Issues: Damaged or loose wiring connections to the flow switch can cause it to fail to detect water flow.
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 require professional expertise. Attempting to fix it yourself can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F58 fault could be around £150 to £250, primarily due to the need for a qualified engineer to inspect and potentially replace the flow switch or repair wiring issues.
