Worcester Bosch Code Plug 8716117164

The Worcester Bosch code plug, part 8716117164, is a small configuration component fitted to Greenstar 25i ErP combi boilers. It tells the appliance control board which fuel the boiler is set up for and applies the matching operating parameters. Fitting the correct plug keeps the combustion settings aligned with the specific appliance variant.

• The boiler fails to fire or locks out after a control board or gas valve change
• Combustion readings sit outside the range expected for the fuel type in use
• Fault codes appear that relate to gas type or appliance configuration
• The appliance runs on the wrong fuel profile following an LPG or natural gas conversion
• The plug is damaged, corroded or missing from its socket on the board

• Match the GC number on the appliance data badge against the compatibility list before ordering.
• Confirm whether the boiler is the LPG or natural gas variant, as the two use different code plugs.
• Quote alternative number 1031359 if your supplier lists the part under a different reference.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
