What does the Glow-worm Easicom E690 fault code mean?
The E690 fault code on the Glow-worm Easicom indicates a problem with the flue gas pressure sensor, which is responsible for monitoring the pressure of flue gases. This fault can prevent the boiler from operating safely and efficiently, requiring immediate attention.
Common Causes
- Blocked Flue: A blockage in the flue system can cause incorrect pressure readings, leading to the E690 fault.
- Faulty Pressure Sensor: The flue gas pressure sensor itself may be malfunctioning or damaged, resulting in inaccurate pressure measurements.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer to diagnose and repair this fault, as working with gas appliances can be dangerous. Attempting to fix it yourself could lead to safety hazards.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for the E690 fault could range from £150 to £250, depending on whether the issue is a blocked flue or a faulty sensor replacement. This estimate includes labour and parts, reflecting the complexity of diagnosing and resolving flue-related issues.
