What it is

The Baxi 5114341 is a high voltage wiring harness kit for Baxi 100/2 HE Plus, 50/2 HE Plus and 80/2 HE Plus gas boilers. It carries mains-voltage connections between the boiler's electrical components, forming part of the appliance's internal wiring loom. The kit is supplied as a heat-only harness assembly.

Signs this part needs replacing

  • Boiler fails to fire or cuts out intermittently with no obvious mechanical cause
  • Visible scorching, melting or discolouration on the harness insulation or connectors
  • Brittle, cracked or snapped wiring within the loom
  • Loose, corroded or heat-damaged spade terminals that will not seat securely
  • Faults that change when the harness or its connectors are moved

Before you order

  • Confirm the boiler model and GC number against the fitment list above
  • Inspect the existing harness routing and connector count before removal
  • Isolate the electrical supply and follow the manufacturer's wiring diagram when fitting
  • Check that the fault is not traced to another component on the same circuit
