6.3 Setting the water

Setting the water hardness regulates how
frequently you are requested to descale
the appliance. The harder the water, the
more frequently the appliance has to be

a water filter (see section 7.5 Using a water
filter on page 48).

table Water hardness range on page 51.

6.4 Activating/deactivating

vated. If it is activated, the coffee system is
rinsed after being switched off.
