Worcester Bosch Code Plug 35C LPG 8716119898

The Worcester Bosch code plug is a small configuration component used on the appliance's control electronics. It carries the settings that tell the board which fuel the appliance is set up for, in this case the 35C LPG variant. The plug is a serviceable item and is normally handled when a board is swapped or when the appliance's fuel configuration needs to be matched to the installation.

• The appliance reports a configuration or fuel-type related fault after a board change
• The boiler runs incorrectly following conversion to LPG operation
• The plug has been lost, damaged or removed and the board no longer holds the correct setup
• Combustion readings stay outside the expected range after commissioning, pointing to a configuration mismatch
• A replacement board has been fitted and the original code plug cannot be reused

• Check the appliance data plate and the existing code plug to confirm the 35C LPG variant matches your installation
• Compare the number moulded or printed on the plug with 8716119898 or 8904999 before ordering
• Confirm the appliance model and serial number with the manufacturer's literature if the plug is missing
