What it is

The Baxi 7662181 is a pump wiring harness used on Baxi ErP Combi boilers. It connects the circulating pump to the appliance's electrical control circuit, carrying the supply and control signals that run the pump. It is a manufacturer part specific to the Baxi 200 and 400 ErP Combi families.

Signs this part needs replacing

  • The pump does not run when there is a call for heat or hot water
  • Pump operation is intermittent, with the pump cutting in and out
  • Visible damage to the harness, such as cracked insulation, chafing or exposed conductors
  • Discoloured, scorched or brittle wiring at the pump plug or connector
  • A loose or poor-fitting connector at the pump, causing an unreliable electrical connection

Before you order

  • Confirm your appliance model against the fit list above before ordering
  • Check the existing harness and pump connector for damage so the fault is correctly identified
  • Isolate the electrical supply to the appliance before inspecting or replacing the harness
  • Check the part number on the existing harness where it is legible
