What does the Ideal Logic Plus F22 fault code mean?
The F22 fault code on the Ideal Logic Plus 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 supply, causing the pressure to drop below the operational threshold.
- Air Locks: Trapped air within the heating system can prevent water from circulating properly, leading to a dry fire condition.
Can I fix it myself? (DIY)
If you are comfortable, you can check the pressure gauge on your boiler. If the pressure is below 1 bar, you can attempt to repressurise the system by using the filling loop. However, if you suspect any gas or electrical issues, it is crucial to call a Gas Safe Engineer for safety reasons.
Estimated Repair Cost (2026 UK Prices)
Repair costs for addressing the F22 fault may range from £100 to £200, depending on whether it involves repressurising the system or fixing leaks. If parts need to be replaced, such as a pressure relief valve, costs may increase accordingly.
