What it is

The Worcester Bosch code plug 1000 is a small configuration component used inside Greenstar CDI combi appliances. It carries the appliance coding that the control board reads to identify the boiler variant and its operating parameters. Fitting the correct code plug keeps the boiler running to the manufacturer's intended settings for that model and fuel type.

Signs this part needs replacing

  • The boiler locks out or fails to fire after a board or code plug change
  • Fault codes appear that point to an appliance configuration or identification problem
  • The appliance runs on settings that do not match its model or fuel type
  • Erratic or incorrect operation following service work on the control side of the boiler
  • A damaged, corroded or loose code plug that no longer seats correctly in its housing

Before you order

  • Check the GC number and appliance serial plate to confirm the exact model and fuel variant before ordering.
  • Confirm the alternative number 1012963 against the part you are replacing.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
