What does the Baxi 600 Series E380 fault code mean?
The E380 fault code on the Baxi 600 Series indicates a flame failure during the domestic hot water (DHW) operation. This means that the boiler is unable to detect a flame when it attempts to heat water, which can prevent hot water from being supplied.
Common Causes
- Blocked Flue: A blockage in the flue system can prevent proper ventilation, leading to flame failure.
- Faulty Flame Sensor: If the flame sensor is dirty or malfunctioning, it may not detect the flame, causing the boiler to shut down.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for any gas or electrical issues, as working on these systems can be dangerous. However, you can check for any visible blockages in the flue or ensure that the boiler is reset properly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E380 fault could range around £150 to £250, primarily depending on whether the flame sensor needs cleaning or replacement, which typically costs around £100 to £150, plus labour.
