Information
If the descaling programme has been
interrupted, e.g. by unintentionally switch-
ing the appliance o, you must switch
the appliance on again and follow the
instructions from step 9. The appliance is
then ready for operation, even if it has not
been completely descaled. For complete
descaling, you must run the descaling
programme from the beginning.
7.5 Using a water lter
The use of a water lter extends the ser-
vice life of the appliance and the appliance
has to be descaled less frequently. The
water lter lters calcium and other pollut-
ants out of the water.
Only use Melitta® Pro Aqua lter cartridges
for fully automatic coee machines.
Observe the processing instructions on
the packaging of the water lter.
Information
When using and regularly replacing the
Melitta® Pro Aqua lter cartridge, the
appliance only needs to be descaled once
a year.
This information is based on an average
of 6coee beverages with 120ml per day
and 6 lter changes per year.

lter
The water lter(21) is screwed into and
unscrewed from the thread(22) on the
base of the water tank(1).
Information
The water lter should not be left standing
dry for a long period of time. When it is
not used for a long time, we recommend
storing the water lter in a vessel lled
with tap water in the refrigerator.
Inserting the water lter
Requirement: The appliance is ready for
operation.
1. Press the "Service" button for
more than 2seconds to call up Service
mode1.
2.  Press the "Service" button
repeatedly until the display for the Filter

3.  Press the "Coee strength"
button until one bean lights up.
4. Follow the instructions from step 3 in
section Changing the water lter.
Changing the water lter
In order to maintain a constant eect of
the water lter, we recommend changing
the water lter every 2months – or when
the device requests you to do so.
The Filter display light requests you to
change the water lter.
Information
 The water hardness cannot be set if you
use a water lter. The water hardness is
automatically set to soft (see sec-
tion6.3 Setting the water hardness on
page41).
 Place the water lter into a vessel lled
with fresh tap water for a few minutes
before inserting it.
