What it is

The Worcester Bosch code plug 1702 (NG) is a configuration component used on Greenstar Highflow 550CDi appliances. It presents the appliance's gas type and setup to the control electronics so the boiler runs to its intended configuration. It is supplied under part number 87144317020.

Signs this part needs replacing

  • The boiler fails to fire or locks out after a PCB or code plug change
  • The appliance is running on the wrong gas configuration
  • Combustion readings sit outside the expected range for natural gas
  • Configuration-related fault codes appear on the appliance

Before you order

  • Confirm the appliance is natural gas (NG), as the LPG version is a different code plug
  • Check the model and GC number against the manufacturer's parts list
  • Compare the number on the existing code plug before ordering
