What does the Glow-worm Easicom E510 fault code mean?
The E510 fault code on a Glow-worm Easicom boiler indicates that the flue gas pressure switch is stuck, preventing the boiler from operating safely. This issue can lead to the boiler shutting down to avoid dangerous conditions.
Common Causes
- Blocked Flue: A blockage in the flue system can prevent proper airflow, causing the pressure switch to remain in a stuck position.
- Faulty Pressure Switch: The pressure switch itself may be malfunctioning or damaged, leading to incorrect readings and the E510 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 electrical components that can be dangerous if handled improperly.
