What it is

The Worcester Bosch 87144310110 is a code plug — a small configuration component that plugs into the appliance control board and identifies the boiler variant and gas type it is set up for. It is used across the Greenstar 40CDI Conventional and Greenstar 40CDI ErP Classic Regular ranges, covering both natural gas and LPG versions. The plug carries the code 1011 and is matched to the specific appliance it is fitted to, so the control board reads the correct operating parameters.

Signs this part needs replacing

  • The boiler fails to fire or repeatedly locks out after a control board change.
  • Fault codes appear that point to a configuration or variant mismatch.
  • The appliance runs with incorrect combustion settings for its gas type.
  • The plug is missing, damaged or has corroded pins on the board connector.
  • A replacement board has been fitted and the original code plug cannot be reused.

Before you order

  • Check the GC number and model on the appliance data badge against the compatibility list, as the code plug is variant-specific.
  • Confirm the code on the existing plug matches 1011 before ordering.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
