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

    “Use cold, preferably filtered water. Do not use demineralized or distilled water or any other liquid.”

    the Infuser Instruction Book - BES840 (US, file BES840_USC_IB_M23_LR.pdf, PDF dated Apr 2023), PDF p. 10, Initial Start Up, NOTE. Source (opens in a new tab), saved October 28, 2026.

  • Water filter

    “The provided water filter helps prevent scale build-up in and on many of the inner functioning components. Replacing the water filter every two months will reduce the need to decalcify the machine. If you live in a hard water area, we recommend you change the water filter more frequently.”

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

    “Water with little or no mineral content may affect the taste of your coffee and how the machine is designed to operate.”

  • 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.”
