What does the Glow-worm Easicom E290 fault code mean?
The E290 fault code on the Glow-worm Easicom indicates a fault with the central heating (CH) heat exchanger. This typically suggests that there is a blockage or a failure within the heat exchanger that is preventing proper heating operation.
Common Causes
- Blockage: Debris or sludge accumulation in the heat exchanger can restrict water flow, leading to overheating and system failure.
- Corrosion: Deterioration of the heat exchanger material over time can cause leaks or inefficiencies, resulting in the fault code being triggered.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as working on the heat exchanger involves gas and electrical components that require professional expertise for safety and compliance.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E290 fault could range from £300 to £500, depending on whether the heat exchanger needs cleaning or replacement. This cost reflects the complexity of the repair and the parts involved.
