the water fi lter, see next chapter).
To measure the water hardness follow the steps below:

Note:
The test strip can only be used for one single measurement.
2 Wait for one minute.

the 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
