What it is

The Vokera 20041473 is a diaphragm supplied for the diverter valve assembly on Vokera gas boilers. It is listed under the Worgas description and forms part of the valve's moving seal arrangement. The diaphragm responds to pressure changes in the valve so the boiler can switch between domestic hot water and central heating operation.

Signs this part needs replacing

  • No domestic hot water, or hot water only when the heating is running
  • Domestic hot water temperature fluctuating or running cold intermittently
  • Boiler failing to switch between central heating and hot water modes
  • Visible splits, perishing or distortion on the diaphragm once the valve is opened
  • Water weeping from the diverter valve body around the diaphragm housing

Before you order

  • Confirm the boiler model and GC number against the appliance data badge
  • Check the diverter valve assembly to confirm the diaphragm is the failed component
  • Inspect the valve body and seating for scale or debris before fitting a new diaphragm
  • Have new seals or gaskets to hand if the valve housing is disturbed during the repair
