What it is

The Buderus Code Plug 73740 is a configuration component used on the Buderus 600-19S gas boiler. It plugs into the appliance's control arrangement to set the boiler coding for that model. It is supplied as a single service part for engineers carrying out repair or setup work.

Signs this part needs replacing

  • The boiler control does not recognise the correct appliance model or configuration.
  • Coding or setup values cannot be set or retained as expected.
  • The plug body, pins or terminals show damage, corrosion or poor seating in its connector.

Before you order

  • Confirm the appliance model is the Buderus 600-19S, as the code plug is model-specific.
  • Check the existing plug for damage or poor contact before ordering a replacement.
  • Have the boiler's model and part number details to hand when discussing the job with the installer or parts counter.
