SETTING WATER HARDNESS

The "DESCALE" message is displayed after a period of time es-
tablished according to water hardness.
The machine is set by default for a hardness of "LEVEL 4". The
machine can also be programmed according to the hardness
of the mains water in the various regions so that the machine
needs to be descaled less often.

18.1 Measuring water hardness

1. Remove the "TOTAL HARDNESS TEST" indicator paper (C1)
from its pack (attached to the English instructions).
2. Immerse the paper completely in a glass of water for one
second.
3. Remove the paper from the water and shake lightly. After
about a minute, 1, 2, 3, or 4 red squares form, depending
on the hardness of the water. Each square corresponds to
one level.

slightly hard water
hard water
very hard water
