Worcester Bosch Code Plug NG 8716122268

The Worcester Bosch 8716122268 is a natural gas (NG) code plug supplied by Worcester Bosch for its Greenstar combi range. The plug carries the appliance configuration data that the control board reads on start-up, allowing the boiler to identify its gas type and model variant. It is a small but critical item on the printed circuit board side of the appliance, and a missing or incorrect plug will stop the boiler configuring itself correctly.

• The boiler will not configure or run after a printed circuit board replacement because the code plug is missing or has not been transferred.
• The appliance locks out or reports a configuration-related fault on start-up.
• Combustion readings sit outside the expected range for the appliance model and gas type.
• The plug body is visibly damaged, scorched or has loose or corroded pins.
• The wrong code plug has been fitted, leaving the board programmed for a different variant.

• Confirm the appliance GC number and model against the compatibility list, as the code plug is specific to the gas type and model variant.
• Check the alternative number 8922938 against any documentation supplied with the boiler.
• If the printed circuit board is being replaced, make sure the existing code plug is transferred or the correct replacement is ordered at the same time.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
