What it is

The water deficiency valve is a Vaillant component listed under part number 115325. It forms part of the water circuit on the MAG Mini 11-0/0 XZ appliance, where it monitors water availability and prevents the unit from operating without an adequate supply. It is a service part intended for replacement when the existing valve no longer functions correctly.

Signs this part needs replacing

  • The appliance fails to fire or locks out when a hot water outlet is opened.
  • Hot water production stops or becomes intermittent despite an adequate water supply.
  • The valve body shows signs of leakage, scale build-up or seizure.
  • The valve does not operate or reset as expected during a service check.

Before you order

  • Confirm the appliance model on the data plate matches the MAG Mini 11-0/0 XZ.
  • Check the part number stamped or labelled on the existing valve against 115325.
  • Verify the fault lies with the valve rather than the water supply, inlet filter or another control component.
  • Consult the manufacturer's parts list for your appliance if the model or build year is uncertain.
