What it is

The pilot burner is a Worcester Bosch component that provides the standing flame used to ignite the main burner in W125-series gas boilers. It sits within the combustion assembly and delivers a small, controlled flame at the pilot position. It is supplied under Worcester Bosch part number 87081057170.

Signs this part needs replacing

  • The pilot flame fails to establish or lights intermittently
  • The pilot lights but will not stay alight, causing the boiler to lock out
  • Sooting, discolouration or visible damage at the pilot burner head
  • Ignition faults that return after the pilot assembly has been cleaned

Before you order

  • Confirm the boiler model and gas type (NG or LPG) against the appliance data badge
  • Check the existing pilot burner is marked with part number 87081057170
  • Inspect the pilot electrode, lead and injector where the fault is one of ignition or flame sensing
