What it is

The Low Volt Wiring Harness is a Glow-worm wiring component that connects the option board within the boiler's control assembly. It carries low voltage signals between the option board and the associated controls on GW HXI and BG330 appliances. The part is supplied under Glow-worm part number 2000801825.

Signs this part needs replacing

  • Fault codes or lockouts traced to the option board circuit
  • Intermittent operation or loss of function on option board controlled features
  • Visible damage to the harness, such as chafed, scorched or brittle insulation
  • Loose, corroded or discoloured connector terminals at either end of the harness
  • Continuity faults on the low voltage circuit when tested

Before you order

  • Confirm the boiler model against the fitment list above
  • Check the existing harness and connectors for damage before removal
  • Verify the fault is on the low voltage option board circuit and not the board itself
  • Note the routing and connector positions before disconnecting the old harness
