What does the Ideal Mini F94 fault code mean?
The F94 fault code on the Ideal Mini boiler indicates an issue with the central heating system inlet, which may be caused by low water pressure or a blockage in the system. This fault prevents the boiler from operating correctly, affecting heating performance.
Common Causes
- Low Water Pressure: Insufficient water pressure in the system can trigger the F94 fault, preventing the boiler from functioning properly.
- Blocked Inlet Filter: A blockage in the inlet filter can restrict water flow, leading to the F94 fault code being displayed.
Can I fix it myself? (DIY)
If you are comfortable, you can check the water pressure on the boiler’s pressure gauge and top it up if it’s low. However, if the issue persists or involves gas or electrical components, it is crucial to call a Gas Safe Engineer for safety reasons.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F94 fault could be around £150 to £250, primarily depending on whether the issue is simply a pressure adjustment or if a blockage requires professional cleaning or part replacement.
