What it is

The Worcester Bosch code plug 1705 is a small configuration component used on Greenstar FS 30CDi Regular floor-standing appliances. It carries the appliance coding that the control board reads to establish how the boiler is set up, so the correct plug must match the model and gas type it is being fitted to. It is supplied under Worcester Bosch part number 87144317050.

Signs this part needs replacing

  • The appliance does not recognise its configured gas type or model variant after a board change.
  • Fault or lockout codes appear that point to an incorrect or unreadable appliance configuration.
  • The boiler fails to run correctly following conversion between NG and LPG operation.
  • The plug is damaged, corroded or has loose or broken pins at the connection.
  • A replacement control board has been fitted and the original coding plug is missing or has been mislaid.

Before you order

  • Check the appliance GC number and serial plate to confirm the exact model and gas type before ordering.
  • Confirm whether the appliance is NG or LPG, as the code plug is specific to the configuration.
  • Have the alternative number 1020886 to hand when cross-referencing against older documentation.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
