What it is

The Worcester Bosch code plug 1002 is a small configuration plug fitted to the appliance control board. It carries the coding that tells the board which model variant and gas type it is installed in, so the electronics run the correct operating parameters. It is used across the Worcester Greenstar and British Gas 430/I families, including CDI Classic combi and 430/I system models in both natural gas and LPG versions.

Signs this part needs replacing

  • The appliance fails to run correctly after a board change or replacement plug is fitted
  • The control board does not recognise the installed model variant
  • Combustion settings cannot be set to the values expected for the appliance
  • Fault codes relating to configuration or model identification appear on the display
  • The plug body or its contacts are damaged, corroded or loose in the board socket

Before you order

  • Check the appliance GC number and model against the compatibility list before ordering, as the same appliance range uses different code plugs
  • Confirm the code plug reference on the existing plug matches 1002
  • Note the alternative part number 1012967 when cross-referencing older stock or documentation
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
