What does the Glow-worm Easicom E480 fault code mean?
The E480 fault code on the Glow-worm Easicom indicates a problem with the flue gas pressure switch, which is responsible for monitoring the pressure of the 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 prevent proper gas flow, triggering the pressure switch fault.
- Faulty Pressure Switch: The pressure switch itself may be malfunctioning or damaged, leading to incorrect readings and the E480 error.
Can I fix it myself? (DIY)
It is strongly advised to call a Gas Safe Engineer for any issues related to gas appliances. Attempting to fix the flue gas pressure switch or related components without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E480 fault is around £150 to £250, depending on whether the flue is cleared or the pressure switch needs replacement. This cost reflects the need for professional service and potential parts involved.
