The harder the water is, the more frequently the IMPRESSA
needs to be descaled. It is therefore important to set the water
hardness.
However, if you are using the CLARIS plus fi lter cartridge
o
and have activated the fi lter, you will not be able to adjust
the water hardness.
The water hardness is set to level 3 in the factory.
o
The symbols in the symbol display show the confi gured degree
of water hardness. The number of symbols corresponds to the
relevant level.
You can fi nd out what the water hardness is, using the Aquadur
test strips enclosed in the Welcome Pack.
l Hold the test strip briefl y (for one second) under fl owing
mains water. Shake off the water.
l Wait for about 1 minute.
l You will then be able to read the degree of water hard-
ness from the discoloration of the Aquadur
and the description on the packaging.
You can now confi gure the water hardness.
