The maker's water guidance

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

From Quick Mill's guidance for this model.

  • Total hardness: up to 3 gpg

    “Three grains or less of hardness is acceptable to be used in the machine. Note: Should your water’s hardness level exceed three grains, then it is strongly recommended that an in tank softener be used or a different source of water that has been tested for hardness. Some bottled water can be extremely hard and should always be tested before using. Using a Brita or PUR style pitcher or faucet filter DOES NOT remove any hardness from the water and should only be used in the machine if your water source is under 3 grains of hardness. Using hard water in the machine will affect its performance and may cause damage to the machine which is not covered under warranty.”
