18. De‐scaling
Your coffee machine features an integrated de‐scaling
program. The de‐scaling operation will take some 60 min.
¾ De‐scaling tablets which are specially designed for the
de‐scaling program of your COFFEE MACHINE are
available at your authorized dealer. Please note that
machine defects or residues in the water cannot be
excluded if you use inappropriate de‐scaling solvents.
¾ If the coffee machine needs de‐scaling, the
corresponding message is displayed. You can still draw
off coffee or hot water/steam and start the de‐scaling
program later. Before starting the de‐scaling program,
the machine must be switched off. Once started, the
de‐scaling operation must not be interrupted. When
using the de‐scaling solvent, immediately remove any
splashes or drips from sensitive surfaces, i.e. natural
stone and wooden surfaces, or take appropriate
precautions.
¾ In any case wait until the de‐scaling solvent is used up
and the tank is empty. Never refill de‐scaling solvent.
