What does the Glow-worm Easicom E870 fault code mean?
The E870 fault code indicates a problem with the flue gas pressure sensor in the Glow-worm Easicom boiler. This sensor is crucial for monitoring the pressure of flue gases, and a fault can lead to unsafe operating conditions.
Common Causes
- Blocked Flue: A blockage in the flue system can prevent proper gas flow, causing the pressure sensor to trigger a fault.
- Faulty Pressure Sensor: The sensor itself may be malfunctioning or damaged, leading to inaccurate readings and the E870 error.
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 require professional handling for safety reasons.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for the E870 fault is around £150 to £250, primarily due to the potential need for a new flue gas pressure sensor and professional labour costs.
