What it is

This is a Worcester Bosch ignition lead, also known as an HT lead, supplied under part number 87161067390. It carries the high-tension spark from the ignition transformer or PCB to the spark electrode on the burner, so the gas/air mixture can be lit on demand. The lead is used across the Worcester Bosch Greenstar and British Gas badged boiler families, including the 430/I, 532/I and 537/I ranges.

Signs this part needs replacing

  • The boiler attempts to fire but there is no spark at the electrode.
  • Repeated ignition lockouts, particularly on first start-up or after a period of no demand.
  • Visible cracking, hardening or scorching of the lead insulation, or exposed conductor near the electrode end.
  • Arcing or tracking to earth along the lead instead of at the electrode tip.
  • Intermittent ignition faults that come and go with movement of the lead or the boiler casing.

Before you order

  • Check the appliance GC number and serial plate against the compatibility list to confirm the lead is correct for your model.
  • Compare the numbers on the existing lead with the alternative and previous numbers listed here, as Worcester Bosch has used several references for this item.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
