What does the Glow-worm Easicom E700 fault code mean?
The E700 fault code on the Glow-worm Easicom indicates an open circuit in the flue gas pressure sensor. This typically means that the boiler is unable to detect the correct flue gas pressure, which can prevent it from operating safely.
Common Causes
- Blocked Flue: A blockage in the flue system can prevent proper gas flow, leading to pressure issues.
- Faulty Pressure Sensor: The flue gas pressure sensor itself may be malfunctioning or damaged, resulting in incorrect readings.
Can I fix it myself? (DIY)
It is strongly advised to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that can be dangerous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the E700 fault could be around £150 to £250, depending on whether the issue is a blocked flue or a faulty sensor replacement, which can vary in price and labour costs.
