The maker's water guidance

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

From ACS's guidance for this model.

  • Descaling

    “Even if you use bottled water of a low mineral content or filters/filter jugs, eventually the machine will require descaling. The only system that completely removes the need for descaling is softening, or Reverse Osmosis with remineralisation using non scaling ions.”
