What it is

The Vaillant 091551 ignition wire is the high-voltage lead that carries the spark from the ignition transformer or PCB to the ignition electrode on Vaillant Ecomax gas boilers. It forms part of the ignition circuit and must be sound for the burner to light reliably. The lead is supplied as a single wire for the Ecomax range.

Signs this part needs replacing

  • Boiler fails to light or repeatedly goes to lockout with no spark at the electrode
  • Visible cracking, charring or brittle insulation on the ignition lead
  • Spark tracking or arcing to earth along the lead instead of at the electrode tip
  • Intermittent ignition, with the boiler lighting on some attempts but not others
  • Damaged or corroded terminal ends where the lead connects to the electrode or ignition source

Before you order

  • Confirm your boiler model against the fitment list above before ordering
  • Check the existing lead for the part number 091551 where it is marked
  • Inspect the ignition electrode and its gap at the same time, as a worn electrode can mimic a faulty lead
  • Isolate the appliance and follow the manufacturer's instructions before removing any ignition components
