What does the Glow-worm Energy F26 fault code mean?
The F26 fault code on a Glow-worm Energy boiler indicates a fan fault, which typically means that the fan is not operating correctly or is not detected by the boiler’s control system. This can lead to issues with combustion and overall boiler performance.
Common Causes
- Blocked Fan: Debris or obstructions may prevent the fan from spinning freely, affecting airflow.
- Faulty Fan Motor: The fan motor may have failed or developed an electrical fault, preventing it from operating.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair the issue, as working on gas appliances can be dangerous and requires professional expertise.
