What does the Glow-worm Easicom E410 fault code mean?
The E410 fault code indicates an open circuit in the domestic hot water (DHW) sensor of the Glow-worm Easicom boiler. This means that the boiler is unable to read the temperature of the water, which can prevent it from functioning correctly.
Common Causes
- Faulty DHW Sensor: The sensor itself may be damaged or malfunctioning, leading to an open circuit.
- Wiring Issues: There could be a break or short in the wiring connecting the DHW sensor to the control board.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair this issue, as it involves electrical components and gas safety regulations.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for replacing the DHW sensor is around £120, including parts and labour. This is based on the typical cost of the sensor and the time required for a qualified engineer to complete the repair.
