How to fix Glow-worm Easicom fault code E710

What does the Glow-worm Easicom E710 fault code mean?

The E710 fault code on the Glow-worm Easicom indicates a flue gas pressure short circuit, which suggests that the boiler is detecting an issue with the flue gas pressure. This can lead to improper combustion and may pose a safety risk if not addressed promptly.

Common Causes

  • Blocked Flue: A blockage in the flue system can prevent proper gas flow, leading to pressure issues.
  • Faulty Pressure Sensor: A malfunctioning pressure sensor may incorrectly report flue gas pressure, triggering the fault code.

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 handled improperly. Attempting DIY repairs could void your warranty and pose safety risks.

Estimated Repair Cost (2026 UK Prices)

The estimated repair cost for resolving an E710 fault could be around £150 to £250, primarily for diagnosing the issue and potentially replacing a faulty pressure sensor or clearing a blocked flue. The cost may vary depending on the specific repairs needed and the engineer’s rates.
