What it is

The Worcester Bosch 87144311350 is a code plug supplied in the 1135 LPG variant. It is a small plug-in connector that sets the configuration code read by the appliance control board, so the boiler recognises the correct fuel and model variant it is installed on. It belongs to the Greenstar 24i Junior family of Worcester Bosch gas boilers.

Signs this part needs replacing

  • The boiler fails to fire or drops into lockout after a board or plug change
  • The appliance runs on the wrong fuel configuration, giving poor combustion or repeated flame supervision faults
  • Intermittent operation or unexplained fault codes that clear when the plug is reseated
  • Visible damage to the plug body, bent pins or corrosion on the connector
  • The plug is missing altogether after service work on the control board

Before you order

  • Check the model and GC number on the appliance data badge against the compatibility list above before ordering
  • Confirm the code plug variant matches the fuel type of the appliance, as LPG and NG versions are not interchangeable
  • Note the alternative number 2243847 when cross-referencing older documentation
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
