The effectiveness of the filter is exhausted after about 50 l of water. (See chap-
ter 5.2 for changing filters.)
Important:
Even if the display shows nothing, the filter should be changed after two
months at the latest even if little coffee was brewed. (See chapter 5.2 Rinsing filter by
hand.)
Without filter
If you do not want to use a filter anymore, the filter setting must be reprogrammed to OFF.
This is important since without a filter it is necessary to decalcify the coffee machine.
• Using the on/off button (2), switch your coffee machine OFF (standby mode).
• Press the service button (7) for about 4 sec. to enter program mode.
• The

• Press the service button (7) for about 4 sec. to confirm.
• Programming is completed and the system is in standby mode again.
☛
Don't forget to program the water hardness (see section 4.2).
4.2 Water hardness
Depending on the hardness of the water in your region and whether you are using a
filter (see chapter 4.1), your coffee machine must be decalcified sooner or later. So that
the system can show when decalcification is necessary, you must first enter the cor-
rect water hardness setting before using the coffee machine for the first time.
First test your water with the included test strip:
• Insert the strip into the water briefly and shake excess water off.
• After about one minute, you can read the result from the red dots.
• The following can be used to interpret the reading:
– 1 red dots = 1–7° dH / 1–12.6° fH =
– 2 red dots = 8–14° dH / 12.7–25.2° fH =
– 3 red dots = 15–21° dH / 25.3–37.8° fH =
– 4 red dots = > 21° dH / > 37.8° fH =
☛
Set your coffee machine to level 1
if no dots turn red.
The basic factory setting is level 3
• Using the on/off button (2), switch your coffee machine OFF (standby mode).
• Press the service button (7) for about 4 sec. to enter program mode.
• The
symbols light up one after another. (The
symbol for water hard-
ness will not light up if the filter is set to ON; see chapter 4.1).
• Wait until the
symbol for water hardness lights up and press the selection knob
(4) to confirm your selection.
