What does the Baxi EcoBlue E125 fault code mean?
The E125 fault code on a Baxi EcoBlue 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
- Faulty Fan: The fan may have failed due to wear and tear or electrical issues, preventing it from spinning properly.
- Blocked Flue: A blockage in the flue system can restrict airflow, causing the fan to malfunction or not operate at all.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any repairs related to the fan or electrical components, as these can pose safety risks. Attempting to fix gas appliances without proper training can be dangerous.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for a fan replacement on a Baxi EcoBlue boiler is around £250 to £350. This includes the cost of the replacement part and labour, as fan issues often require professional intervention to ensure safe operation.
