How to fix Ideal Mini fault code F92

What does the Ideal Mini F92 fault code mean?

The F92 fault code on the Ideal Mini indicates a central heating system outlet fault, which typically suggests that the boiler is not receiving the correct flow of water from the heating system. This can lead to overheating and potential damage if not addressed promptly.

Common Causes

  • Blocked Radiators: Radiators may be blocked with sludge or air, preventing proper water flow.
  • Faulty Pump: A malfunctioning circulation pump can fail to move water effectively through the heating system.

Can I fix it myself? (DIY)

If you are comfortable, you can check for air in the radiators and bleed them if necessary. However, for issues related to the pump or any gas/electrical components, it is crucial to call a Gas Safe Engineer to ensure safety and compliance with regulations.

Estimated Repair Cost (2026 UK Prices)

Repair costs for the Ideal Mini F92 fault can range from £150 to £300, depending on whether the issue is a simple radiator bleed or a more complex pump replacement. A new pump typically costs around £200, plus labour.
