What does the Glow-worm Easicom F22 fault code mean?
The F22 fault code on the Glow-worm Easicom indicates a dry fire condition or low water pressure in the system. This typically means that the boiler is unable to detect sufficient water flow, which can lead to overheating and potential damage if not addressed.
Common Causes
- Low Water Pressure: This can occur due to leaks in the system or insufficient water supply, leading to inadequate pressure for the boiler to operate safely.
- Air in the System: Trapped air can prevent water from circulating properly, causing the boiler to register a dry fire condition.
Can I fix it myself? (DIY)
If you are comfortable, you can check the pressure gauge on the boiler; it should typically be between 1-1.5 bar. If it is low, you can re-pressurise the system by following the manufacturer’s instructions. However, if you suspect 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 F22 fault could range from £100 to £200, primarily depending on whether it involves re-pressurising the system or fixing leaks. If a component replacement is necessary, costs may increase accordingly.
