What it is

The water flow selector handle is a control knob manufactured by Worcester Bosch. It fits Worcester Bosch gas boilers and is used to select or change the water flow setting on the appliance. The handle is turned by hand to move the water flow selector to the required position.

Signs this part needs replacing

  • The handle is cracked, split or has broken away from its mounting.
  • The handle spins or slips on the spindle without changing the water flow setting.
  • The handle is loose and no longer holds its selected position.
  • The handle is stiff or difficult to turn by hand.
  • The handle has come away from the appliance and cannot be refitted securely.

Before you order

  • Confirm the boiler model matches Worcester W11 B31 S7895.
  • Compare the part number on the existing handle, where visible, with 87020003040.
  • Check the condition of the spindle or shaft the handle mounts to, so the new handle seats correctly.
