The maker's water guidance
From Rocket Espresso's guidance for Appartamento (2024 manual, before the 2025 update).
Total hardness: 4–7 °fH
“The water hardness must be between 4 - 7 °f (French) / 2 - 4 °d (German).”
Total hardness: 2–4 °dH
“The water hardness must be between 4 - 7 °f (French) / 2 - 4 °d (German).”
Water type
“The machine has to operate with clean soft drinking water. Never attempt to operate the machine with water of a hardness other than that specified in paragraph 3.6.”
Very pure water
“Use fresh, filtered water to fill the tank. Do not use distilled water (see par. 3.6 page 51).”
Water filter
“The manufacturer recommends inserting a softener bag (2) in the water tank.”
Descaling
“ROCKET does not recommend removing limescale from the espresso machine. Contact an authorised ROCKET centre for descaling.”
Very pure water
“Conversely, highly “pure” waters may interfere with the electronic signals read by the machine for both boiler level and water tank level indications. Use filtered water.”
