Measuring and Programming Water Hardness
Water hardness measuring is very important in order to defi ne the machine
descaling frequency and to install the “INTENZA+” water fi lter (for more
details on the water fi 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 to red, then consult this table.
Note:
The numbers on the water hardness test strip correspond to the water
hardness adjustment settings.
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 fi lter (see next chapter).
