What it is
The code plug is a small configuration component used on Worcester Bosch Greenstar 28i Junior appliances. It carries the appliance coding that the control board reads to establish how the boiler is set up, so the electronics match the model and fuel type fitted. Part number 87144311370 is the 1137 code plug variant.
Signs this part needs replacing
- The boiler reports a configuration or coding fault after a board change.
- The appliance fails to run correctly on the fuel type it is installed for.
- Combustion readings sit outside the expected range for the model and gas type.
- Intermittent lockouts or start-up faults that persist after the board and loom have been checked.
- A code plug that is missing, damaged or has corroded pins.
Before you order
- Check the GC number and model on the appliance data badge against the compatibility list, as the code plug is model and fuel specific.
- Confirm the existing code plug reference before ordering, since LPG and NG variants use different coding.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
