SETTING WATER HARDNESS

The DESCALE message is displayed after a period
of time established according to water hardness.
The coffee maker is factory set for a hardness
value of 4 (very hard water). The machine can
also be programmed according to the hardness of
the mains water in the various regions, varying
the frequency with which the message is displa-
yed.

water for about a 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.
Level 1
