What it is

The Buderus 75304 is a high voltage cable wiring harness used on Buderus 800 series oil boilers. It carries the high voltage connections between the boiler's control and ignition components as part of the appliance wiring loom. The harness is supplied as a single assembly with terminated ends for direct connection to the boiler's electrical points.

Signs this part needs replacing

  • Visible burning, scorching or discolouration on the cable insulation or connector housings
  • Cracked, brittle or frayed insulation along the length of the harness
  • Loose, corroded or heat-damaged terminals that will not seat securely
  • Intermittent ignition or boiler lockout traced to a break in the high voltage wiring
  • Continuity test failure across one or more conductors in the harness

Before you order

  • Confirm the boiler model against the fit list above, as the harness suits the 800 series only
  • Check the part number on the existing harness or in the boiler documentation
  • Inspect the connector types and pin layout on the existing harness against the replacement
  • Check the ignition and control components the harness connects to for damage before fitting
