The maker's water guidance

What the maker says this machine needs from its water. This is machine care, not drinking-water advice.

From Breville's guidance for this model.

  • Very pure water

    “Do not use any other liquid apart form cold mains/tap water. We do not recommend the use of highly filtered, de-mineralized or distilled water as this may affect the taste of the coffee and how the espresso machine is designed to function.”

From Breville's guidance for Breville espresso machines (US support article; no models named).

  • Total dissolved solids (TDS): 50–150 ppm

  • Remineralization
