What does the Ideal Mini F58 fault code mean?
The F58 fault code on the Ideal Mini indicates a problem with the central heating return temperature, suggesting that the return water temperature is either too low or not being detected correctly. This can lead to inefficient heating and potential system issues if not addressed.
Common Causes
- Low Water Flow: Insufficient water flow through the system can cause the return temperature to drop below the expected level.
- Faulty Temperature Sensor: A malfunctioning temperature sensor may not accurately read the return temperature, triggering the fault code.
Can I fix it myself? (DIY)
It is advisable to call a Gas Safe Engineer for this issue, as it may involve gas or electrical components that require professional expertise. Attempting to fix it yourself could pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F58 fault could be around £150 to £250, primarily depending on whether a temperature sensor replacement is needed or if there are issues with the water flow that require further investigation.
