What does the Worcester Bosch Greenstar 8000 Lifestyle E258 fault code mean?
The E258 fault code indicates a pump feedback fault, which means the boiler is not receiving the expected signal from the pump. This can lead to inadequate circulation of water, affecting heating efficiency.
Common Causes
- Faulty Pump: The pump may be malfunctioning or have failed, preventing it from operating correctly.
- Wiring Issues: Damaged or loose wiring connections between the pump and the control board can disrupt communication, leading to the fault code.
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 DIY repairs may void your warranty.

The estimated repair cost for resolving an E258 fault could range from £150 to £300, primarily depending on whether the pump needs replacing or if wiring repairs are required. This cost reflects the typical price for parts and labour in the UK.
