Measuring and Programming Water Hardness
Water hardness measuring is very important in order to de ne the descal-
ing frequency and to install the “INTENZA+” water  lter (for more details on
the water  lter, see next chapter).
To measure the water hardness follow the steps below:
1
Immerse the water hardness test strip (supplied with the machine) in
water for 1 second.
Note:
The test strip can only be used for one single measurement.
2
Wait for one minute.
3
Check how many squares have changed colour to red and then refer to
the table.
Note:
The numbers on the water hardness test strip correspond to the water
hardness.
More precisely:
1 = 1 (very soft water)
2 = 2 (soft water)
3 = 3 (hard water)
4 = 4 (very hard water)
The letters correspond to the references that are located at the base of the
“INTENZA+” water  lter (see next chapter).
