What does the Ideal Mini F22 fault code mean?
The F22 fault code on the Ideal Mini indicates a dry fire condition or low water pressure within the system. This typically means that the boiler is unable to detect sufficient water flow, which can lead to overheating and potential damage.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system or insufficient water being added to the boiler.
- Air in the System: Trapped air can prevent proper water circulation, leading to low pressure and triggering the F22 fault.
Can I fix it myself? (DIY)
You can attempt to fix the issue by checking the pressure gauge on the boiler. If the pressure is below 1 bar, you can re-pressurise the system using the filling loop. However, if the problem persists or involves gas components, it is essential to call a Gas Safe Engineer.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the F22 fault could be around £150 to £200, primarily for a service call and potential parts replacement, such as a pressure relief valve or filling loop, if necessary.
