What does the Worcester Bosch Greenstar 8000 Lifestyle E274 fault code mean?
The E274 fault code indicates a pump diagnostics error, which suggests that the boiler’s pump is not functioning correctly. This can lead to inadequate circulation of water within the system, potentially causing overheating or other operational issues.
Common Causes
- Blocked Pump: Debris or sediment may be obstructing the pump, preventing it from circulating water effectively.
- Electrical Fault: Issues with the pump’s electrical connections or the control board may disrupt its operation.
Can I fix it myself? (DIY)
It is recommended to call a Gas Safe Engineer to diagnose and repair the issue, as working with gas and electrical components can be dangerous. Attempting to fix it yourself may void the warranty or cause further damage.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for addressing the E274 fault code is around £150 to £250, primarily due to the potential need for a new pump or electrical components, along with labour costs for a qualified engineer.
