What does the Baxi Duo-tec F62 fault code mean?
The F62 fault code on a Baxi Duo-tec boiler indicates a central heating pump fault, which typically means that the pump is not functioning correctly or is blocked. This can lead to inadequate heating and potential overheating of the boiler.
Common Causes
- Blocked Pump: Debris or sludge in the system can obstruct the pump, preventing it from circulating water effectively.
- Electrical Fault: Issues with the pump’s electrical connections or the pump itself may cause it to fail to operate.
Can I fix it myself? (DIY)
While some minor issues can be checked, such as ensuring the pump is not blocked, it is strongly advised to call a Gas Safe Engineer for any repairs involving gas or electrical components to ensure safety and compliance with regulations.
