What does the Baxi Duo-tec F26 fault code mean?
The F26 fault code on the Baxi Duo-tec 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 issue can prevent the boiler from functioning properly, leading to heating and hot water failures.
Common Causes
- Blocked Fan: Debris or obstructions may prevent the fan from spinning freely.
- Faulty Fan Motor: The fan motor may have failed, leading to a lack of airflow and triggering the fault code.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as working with gas appliances can be dangerous. Attempting to fix electrical or gas components without proper training can lead to serious safety risks.
