What does the Glow-worm Easicom E250 fault code mean?
The E250 fault code on the Glow-worm Easicom indicates a central heating (CH) temperature fault, which typically means that the boiler is unable to reach or maintain the desired temperature for the heating system. This can lead to insufficient heating in your home.
Common Causes
- Faulty Temperature Sensor: The temperature sensor may be malfunctioning, providing incorrect readings to the boiler’s control system.
- Blocked Heat Exchanger: A blockage in the heat exchanger can prevent proper heat transfer, causing the boiler to struggle to maintain the correct temperature.
Can I fix it myself? (DIY)
It is advisable to call a Gas Safe Engineer for this issue, as it involves gas and electrical components that require professional expertise. Attempting to fix these issues without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E250 fault could be around £150 to £250, primarily depending on whether the temperature sensor needs replacement or if the heat exchanger requires cleaning or servicing.
