B) WATER HARDNESS
The hardness of tap water varies in each region, so we recommend testing the hardness of the water used with the coffee
machine. After programming the coffee machine with the water hardness, the machine will warn you about the next de-
calcification process required by the system.
First, test the hardness of the water. Drop a reagent strip in the water during 1 second. You will see how one box on the strip chang-
es its colour; the hardness will be equal to this colour. Please, check the packaging of this strip to see the hardness of the water.
After accessing the programming mode:
1. Press the extraction selector for 2 cups.
2. Select the hardness of the water with the + or - buttons of the top
bar.
3. This bar has 5 positions:
0. Level 1
1. Level 2
2. Level 3
3. Level 4
4. Level 5 (default option programmed)
