Regular descaling will prolong the life of your appliance and
will guarantee optimal brewing results for a long time.

for about 30 Minutes in the appliance, before you start with
flushing the appliance.
• To get the best results repeat above-mentioned step once or
twice.
• When finished, flush the appliance twice by repeating the
above-mentioned steps only use water instead.
