What it is

The Ideal 177668 is a mains system wiring harness — the loom that carries mains supply and control connections between the boiler's electrical components. It is manufactured by Ideal for the Logic and Logic+ System boiler ranges. The harness plugs into the appliance's mains circuit, so it is the first point to inspect when a boiler loses power, trips repeatedly or shows an intermittent electrical fault.

Signs this part needs replacing

  • The boiler is completely dead with no display or indicator lights, despite a live supply at the isolator.
  • Fuses blow repeatedly on start-up or during operation.
  • Intermittent faults that appear and disappear when the harness or its connectors are moved.
  • Visible damage to the loom: cracked or brittle insulation, scorch marks, or exposed conductors.
  • Loose, corroded or heat-discoloured plug terminals at the harness ends.

Before you order

  • Confirm the GC number on the appliance data badge against the compatibility list, as the harness is used across several Logic and Logic+ System variants.
  • Check whether the existing harness carries the alternative number 1782496 before ordering, so the correct loom is matched to the appliance.
  • Isolate the mains supply and prove dead before removing or refitting any wiring.
  • Inspect the harness connectors and any associated seals or grommets for damage while the appliance is open.
