What it is

The Worcester Bosch 87070114020 is a gas valve assembly used in the W135 appliance family. It regulates the supply of gas to the burner, opening and closing in response to demand from the appliance's control system. The valve also contributes to stable burner pressure during modulation.

  • The appliance locks out with an ignition or flame supervision fault
  • Flame drops out during operation or fails to modulate correctly
  • Unstable burner pressure or poor combustion readings
  • Evidence of gas leakage around the valve body or its connections

Before you order

  • Check the part number on the existing gas valve before ordering
  • Gas appliance work must be carried out by a Gas Safe registered engineer
