What does the Worcester Bosch Greenstar 8000 Lifestyle E261 fault code mean?
The E261 fault code indicates a pump update fault, which suggests that the boiler’s pump is not functioning correctly or is not receiving the necessary updates from the control system. This can lead to inadequate circulation of water within the heating system, potentially causing overheating or other operational issues.
Common Causes
- Faulty Pump: The pump may be malfunctioning due to wear and tear or electrical issues, preventing it from operating effectively.
- Control Board Issue: A problem with the control board can hinder communication between the pump and the boiler, leading to update faults.

The estimated repair cost for addressing the E261 fault could be around £250 to £400, depending on whether the pump needs replacement or if the control board requires servicing. This estimate includes parts and labour for a qualified engineer.
