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 highly filtered, demineralized, or distilled water in this machine. This may affect the taste of the coffee.”

  • Water filter

    “The provided water filter helps reduce the risk of scale build-up in and on many of the inner functioning components. Replacing the water filter every three months will reduce the need to descale the machine.”

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

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

    “Water that lacks in mineral content can contribute to sourness and acidic taste in the espresso, it is recommended to use water that has mild amount of minerals like soft filtered water, spring water, well water, these types of water ideally measure in between 50-150 ppm (parts permillion) in dissolved solids.”

  • Very pure water

  • Remineralization

    “Avoid using RO water if the filtration process removes nearly all of its mineral content. For applicable models, RO water may be suitable if some mineral content has been added back to the finished water.”
