What it is
The Worcester Bosch 8716121407 is a code plug supplied for Greenstar 4000 System boilers in the GR4700iW family. The plug carries the model coding that the boiler's control board reads to identify the appliance variant and set the correct operating parameters. It is a small, model-specific component and the coding it holds is tied to the boiler it is fitted to.

- Fault codes appear that point to incorrect or missing appliance coding.
- The appliance runs with parameters that do not match the installed variant.
- A damaged, corroded or loose code plug in the control area.
