Descaling (decalcification)
To prolong the life of the coffee machine, it is critical to
clean the unit from scale in a timely manner. The des-
caling frequency depends on water hardness in your
region. To determine the level, we recommend using
paper indicator testers that are immersed in water and
change color depending on the amount of calcium,
magnesium and iron. Based on the data obtained, it is
necessary to choose one of the following decalcifica-
tion frequency schemes:
Level Water hardness,
mg/l
Level 1 0-50
Level 2 51-120
Level 3 151-250
Level 4 251-425
To descale, use specialized coffee machine cleaners in
the form of liquids or tablets.
