chine 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.

Measuring water hardness

1. Remove the "TOTAL HARDNESS TEST" indicator paper 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
