16.11 Information about decalcify
Lime scale builds up in the IMPRESSA as a result of normal use. The degree of calcification depends on the hardness of the water you use. The IMPRESSA Z5 recognizes when you should run a de- calcifying cycle. The machine will still make coffee, hot water and frothed milk. However, we recommend that you should decalcify the machine (Chapter 18) within the next few days.
