About Worcester Bosch Greenstar 2000 gas boiler

Worcester Bosch Greenstar 2000 gas boiler is indexed in the Boilers and HVAC directory for United Kingdom. This page brings the available product context, model references, documentation and diagnostic codes together in one place.

The codes below apply only where the linked code page lists this product or model. Confirm the complete model identifier because manufacturers may reuse the same characters across different ranges, generations and control systems.

An error code describes a condition detected by the product; it does not prove that a named component has failed. Follow the exact manual, avoid repeated resets and use an appropriately qualified technician whenever checks require internal access.
