What does the Glow-worm Easicom E430 fault code mean?
The E430 fault code on the Glow-worm Easicom indicates a flue gas temperature fault, which suggests that the boiler is detecting an abnormal temperature in the flue system. This could lead to inefficient operation or potential safety hazards if not addressed promptly.
Common Causes
- Blocked Flue: A blockage in the flue can prevent proper venting of exhaust gases, causing temperature readings to rise excessively.
- Faulty Temperature Sensor: A malfunctioning temperature sensor may provide inaccurate readings, leading to the E430 fault code being triggered.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer to diagnose and fix this issue, as it involves gas and electrical components that can be dangerous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving the E430 fault could be around £150 to £250, depending on whether a sensor replacement or flue cleaning is required. This cost reflects the need for professional service and potential parts replacement.
