What it is

The Vokera 20067491 is a 29mm diaphragm supplied for the Vokera Vision 25S ERP boiler. It is a flexible rubber component used within the appliance's water section, where it responds to changes in flow or pressure to actuate the relevant valve or switch. As a wear item, it is replaced when it perishes, splits or loses its flexibility.

Signs this part needs replacing

  • Domestic hot water demand is not detected, so the boiler does not fire on a tap opening
  • Hot water flow or temperature is erratic, fluctuating or reduced
  • The diverter valve or flow switch does not move through its full travel
  • The diaphragm is visibly split, stretched, hardened or distorted
  • Water is present around the diaphragm housing or the valve it operates

Before you order

  • Confirm the appliance model is the Vokera Vision 25S ERP
  • Check the part number on the existing component or against the manufacturer's parts list for your appliance
  • Verify the diaphragm diameter required is 29mm
  • Check the boiler's GC number against the appliance data badge before ordering
