What does the Worcester Bosch Greenstar 8000 Lifestyle E275 fault code mean?
The E275 fault code indicates a pump monitoring error, which suggests that the boiler’s pump is not functioning correctly or is not being detected by the system. This can lead to inadequate circulation of water, potentially causing overheating and further damage to the boiler.
Common Causes
- Faulty Pump: The pump may have failed mechanically or electrically, preventing it from circulating water properly.
- Wiring Issues: Damaged or loose wiring connections to the pump can result in a lack of communication between the pump and the boiler’s control system.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair this issue, as it involves electrical components and potential gas safety risks. Attempting DIY repairs could lead to further complications or safety hazards.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E275 fault code is around £250 to £400, depending on whether the pump needs replacing or if wiring issues are present. This cost reflects the price of a new pump and the labour involved in diagnosing and fixing the problem.
