What does the Baxi 600 Series E157 fault code mean?
The E157 fault code on the Baxi 600 Series indicates a fan fault, which typically means that the boiler’s fan is not operating correctly. This can prevent the boiler from functioning safely and efficiently, leading to heating issues.
Common Causes
- Blocked Fan: Debris or obstructions may be preventing the fan from spinning freely.
- Faulty Fan Motor: The fan motor may have failed, resulting in a lack of airflow necessary for the boiler’s operation.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as working on gas appliances can be dangerous. Attempting to fix electrical or gas components without proper training can lead to serious safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for a fan replacement on a Baxi 600 Series boiler is around £250 to £350. This includes parts and labour, as the fan itself typically costs between £100 and £200, and professional installation is necessary for safety and compliance.
