Problem Cause and remedy
The descaling process
was started by mistake. The descaling process cannot be stopped once the
“OK” sensor has been touched.
Descaling must be continued through to completion.
This is a safety precaution to make sure the machine
is descaled correctly. This is important for the
longevity and functional efficiency of your coffee
machine.
 Descale the coffee machine (see “Descaling”).
The milk sputters when
it is dispensed. Hissing
noises can be heard
when milk is being
heated up or frothed.
Although the milk
should be frothed, only
hot milk comes out of
the main dispenser. The milk temperature is too high. Good milk froth can
only be achieved with cold milk (below 10°C).

Check the temperature of the milk.
The central dispenser with integrated cappucinatore
is not correctly fitted and is taking in air. Or the
spouts are blocked.

Check whether the central spout has been
assembled correctly. Make sure that all parts are
tightly connected to one another.

If necessary, clean the central spout.
The milk pipework, connections or the intake tube on
the milk flask are blocked.

Clean all parts thoroughly.
The steam jet on the central spout has a blockage.
Push the cleaning brush a max. of 1 cm into the
steam jet.
 Clean the steam jet with the cleaning brush.
