What does the Glow-worm Easicom E660 fault code mean?
The E660 fault code on the Glow-worm Easicom indicates that the flue gas pressure is stuck, which can prevent the boiler from operating correctly. This issue typically arises from problems within the flue system or pressure sensor malfunctions.
Common Causes
- Blocked Flue: A blockage in the flue can restrict the flow of exhaust gases, leading to pressure issues.
- Faulty Pressure Sensor: A malfunctioning pressure sensor may incorrectly read the flue gas pressure, causing the boiler to shut down.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that can be dangerous if not handled correctly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E660 fault could range around £150 to £250, primarily depending on whether the flue needs clearing or the pressure sensor needs replacing.
