What it is

This is a high voltage wiring harness manufactured by Ariston for use in Microcombi 23 MFFI gas boilers. It carries mains-voltage connections within the appliance, linking the boiler's electrical components to the control circuit. It is supplied as a single wiring assembly under part number 998860.

Signs this part needs replacing

  • The boiler has no power or loses power intermittently
  • Visible burning, scorching or discolouration on the wiring or its connectors
  • Cracked, brittle or exposed insulation on the harness
  • Loose or corroded terminals causing intermittent faults
  • The boiler fails to respond to the controls despite a live supply

Before you order

  • Confirm your appliance is a Microcombi 23 MFFI and identify whether it is the LPG or NG variant
  • Check the edition of your appliance against the fitment list above
  • Inspect the existing harness and compare the part number before ordering
  • Verify the fault lies with the wiring rather than the component it connects to
