What it is

The Vaillant 24V wiring harness, part number 0020268769, is an electrical loom used within the appliance's control and low-voltage circuit. It carries 24V signals between components on Vaillant VU 446/5-5 and VU 606/5-5 appliances. It is supplied as a single harness assembly.

Signs this part needs replacing

  • Fault codes or lockouts traced to a break in the low-voltage circuit
  • Intermittent operation or random shutdowns linked to a loose or damaged loom
  • Visible damage to the harness: chafed, cracked or heat-affected insulation
  • Corroded, discoloured or loose connector terminals on the harness
  • Continuity testing shows an open circuit on one or more conductors

Before you order

  • Confirm the appliance model and variant against the fit list above
  • Check the existing harness part number or label before removal
  • Inspect the connector ends and pin count on the failed harness to confirm a match
  • Isolate the appliance electrically before removal and fitting
