What it is

The Vaillant 0020231145 is a wiring harness used across a number of Vaillant domestic gas appliances. It carries the electrical connections between components within the boiler, forming part of the appliance's internal wiring loom. It is supplied as a single harness assembly for the models listed below.

Signs this part needs replacing

  • Intermittent faults or the appliance cutting out during operation
  • Visible damage to the harness, such as chafed, cracked or heat-affected insulation
  • Discoloured, burnt or corroded connector terminals
  • Loose or poor-fitting plugs at the harness ends
  • Fault codes or ignition and fan faults traced to the wiring rather than the component itself

Before you order

  • Confirm your appliance model and GC number against the fitment list above
  • Check the part number on the existing harness or the manufacturer's parts list for your appliance
  • Inspect the connector layout and pin count on the existing harness before removal
  • Isolate the electrical supply and follow the manufacturer's instructions when fitting
