What does the Glow-worm Easicom E800 fault code mean?
The E800 fault code indicates a flue gas pressure fault in the Glow-worm Easicom boiler. This issue typically arises when the flue system is obstructed or there is insufficient airflow, which can lead to dangerous conditions if not addressed.
Common Causes
- Blocked Flue: Debris, bird nests, or other obstructions can block the flue, preventing proper gas venting.
- Fan Malfunction: A faulty fan may not be able to create the necessary pressure to expel flue gases effectively.
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 hazardous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing an E800 fault could range from £150 to £300, depending on whether the issue is a simple flue cleaning or requires fan replacement, which can be more expensive.
