What it is

The pilot electrovalve (part number 87085012490) is a Worcester Bosch component used in the pilot burner assembly of their gas boilers.

Signs this part needs replacing

  • Boiler fails to ignite or locks out repeatedly
  • Pilot flame will not stay lit after ignition
  • No gas flow to the pilot burner when ignition is demanded
  • Audible click from the valve but no pilot flame
  • Intermittent pilot operation or repeated flame failure faults
