What does the Glow-worm Easicom E860 fault code mean?
The E860 fault code on a Glow-worm Easicom boiler indicates a flue gas pressure fault, which suggests that the boiler is not able to vent exhaust gases properly. This can lead to unsafe operating conditions and requires immediate attention.
Common Causes
- Blocked Flue: A blockage in the flue system can prevent proper gas venting, leading to pressure issues.
- Faulty Pressure Switch: A malfunctioning pressure switch may fail to detect the correct flue gas pressure, triggering the fault code.
Can I fix it myself? (DIY)
It is strongly advised to call a Gas Safe Engineer to diagnose and repair this issue, as it involves gas and safety components that require professional expertise.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an E860 fault could range from £150 to £300, depending on whether the issue is a simple flue cleaning or a more complex pressure switch replacement.
