What it is

The Worcester Bosch 87144310090 is a code plug for the Greenstar 30CDI family of conventional and ErP Classic Regular boilers. It plugs into the appliance control board and carries the identification data the board reads to select the correct operating parameters for that model and gas type. It is a small, easily swapped component that is normally replaced when the plug is damaged or when the board needs to be matched to the appliance variant.

Signs this part needs replacing

  • The boiler locks out or fails to run after a control board change.
  • Fault codes appear that relate to appliance identification or configuration.
  • Combustion readings do not match the data plate figures for the installed model.
  • Firing is intermittent, or the appliance behaves as though it is set for the wrong variant.
  • The plug body is cracked, or its pins are bent, corroded or making poor contact.

Before you order

  • Check the GC number on the appliance data plate against the compatibility list above to confirm the correct variant.
  • Confirm the code plug currently fitted and cross-check it against part number 87144310090 and alternative number 1012981.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
