7 Descaling

Regular descaling prolongs the life of the appliance
and guarantees optimal brewing results and a
constant brewing time for a long time. In case of
normal use (two full jugs of coffee every day),
descale the appliance:
•
2 or 3 times a year if you use soft water (up
to 18dH).
• 4 or 5 times a year if you use hard water
(over 18dH).
You can use white vinegar with 4% acetic acid.
Also an appropriate liquid descaler can be used. In
this case, follow the instructions on the package of
the descaler.
Warning:
B
Never use vinegar with an acetic acid content of
8% or more, natural vinegar, powder descalers
or tablet descalers to descale the appliance, as
this may cause damage.
Fill the water tank till the MAX with
1
white vinegar (4% acetic acid).
Note:

You can also use an appropriate liquid
descaler. In this case, follow the instructions on
the package of the descaler.

2
it in the filter holder to collect the scale.

Remove the paper filter.
Let the appliance complete two more
6
brewing cycles with fresh cold water to
remove all vinegar or descaler residues.
