What does the Ideal Mini F93 fault code mean?
The F93 fault code on the Ideal Mini boiler indicates a problem with the domestic hot water (DHW) system inlet. This typically suggests that there is an issue with the water supply to the boiler, which may affect its ability to provide hot water.
Common Causes
- Blocked Inlet Filter: A blockage in the inlet filter can restrict water flow, leading to the F93 fault code.
- Low Water Pressure: Insufficient water pressure in the system can trigger this fault, preventing the boiler from functioning correctly.
Can I fix it myself? (DIY)
If you are comfortable, check the water pressure gauge on the boiler. If the pressure is below 1 bar, you may need to top it up. However, for any gas or electrical issues, it is crucial to call a Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F93 fault could range from £100 to £200, primarily depending on whether the issue is a simple filter clean or requires more extensive work such as replacing components.
