Cleaning from scale (decalcification)
To prolong the life of the coffee machine, it is critical to
clean the unit from scale in a timely manner. The descaling
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 de-
pending on the amount of calcium, magnesium and iron.
Based on the data obtained, it is necessary to choose one
of the following decalcification frequency schemes:
Level Water hardness,
mg/l
Level 1 0-50
Level 2 51-120
Level 3 151-250
Level 4 251-425
You can use calcium powder or tablets that are designed for
automatic coffee machines and other food and drink mak-
ing devices as a cleaning agent.
– Make the descaling solution according to the cleaning
agent instructions.
