What it is

The Main Wiring Harness 24V is a 24-volt electrical loom used on Main Multipoint FF water heaters. It carries low-voltage control and signal wiring between the appliance's electrical components. The harness is supplied as a complete assembly for routing and connection within the heater.

Signs this part needs replacing

  • Intermittent operation or repeated lockouts traced to a broken or loose harness connection
  • Visible damage to the loom, such as cracked insulation, chafing or exposed conductors
  • Burnt, discoloured or corroded terminals and connector plugs
  • Faults that come and go when the harness or its plugs are moved
  • No supply reaching a component that the harness feeds

Before you order

  • Confirm your appliance model is a Main Multipoint FF or Multipoint FF ErP
  • Check the GC number on the appliance data badge against the model listed
  • Inspect the existing harness and compare connector layout and plug count before ordering
  • Isolate the electrical supply to the appliance before any inspection or replacement work
