What does the Worcester Bosch Greenstar 8000 Lifestyle E276 fault code mean?
The E276 fault code indicates a pump feedback error, which suggests that the boiler’s control system is not receiving the expected signal from the pump. This can lead to inadequate circulation of water, potentially causing overheating or system failure.
Common Causes
- Faulty Pump: The pump may be malfunctioning or completely failed, preventing it from circulating water properly.
- Electrical Connection Issues: Loose or damaged wiring connections to the pump can disrupt communication between the pump and the boiler’s control board.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer for this issue, as it involves electrical components and potentially gas-related systems. Attempting to fix it yourself could pose safety risks.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for resolving an E276 fault code is around £250 to £400. This includes the cost of a new pump and labour, as replacing the pump is often necessary to resolve the issue.
