What does the Glow-worm Easicom E370 fault code mean?
The E370 fault code indicates a problem with the domestic hot water (DHW) pump overrun, which means the pump is not running for the required duration after the heating demand has ceased. This can lead to inadequate hot water supply and potential overheating issues within the boiler.
Common Causes
- Faulty DHW Pump: The pump may be malfunctioning or blocked, preventing it from operating correctly.
- Control Board Issue: A fault in the control board may not be sending the correct signals to the pump, causing it to fail to run as needed.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as it involves electrical components and potential gas safety risks. Attempting to fix it without proper training could lead to further damage or safety hazards.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E370 fault could range from £150 to £250, primarily depending on whether the DHW pump needs replacement or if the control board requires servicing. This estimate includes parts and labour for a qualified engineer.
