What it is

The Vaillant 010365 is a complete diaphragm for the diverter valve assembly used in Vaillant Turbomax VUW appliances. It responds to pressure changes within the valve to switch the boiler between central heating and domestic hot water operation. This part replaces the earlier code 010357.

Signs this part needs replacing

  • No hot water when a tap is opened, or the boiler fails to switch to domestic hot water mode
  • Intermittent or fluctuating hot water delivery
  • Visible splits, perishing or distortion of the diaphragm
  • Water weeping from the diverter valve area

Before you order

  • Confirm your appliance model and GC number against the fitment list above
  • Check the part number on the existing diaphragm before ordering
  • Note that this diaphragm replaces the earlier code 010357
  • Isolate and drain the appliance before fitting
