Troubleshooting
Issue
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 is dispensed
from the central spout.
Coffee grounds have
settled on the lid to the
drip tray and in the
interior around the brew
unit.

Cause and remedy
The milk temperature is too high. Good milk froth can
only be achieved when cold milk (< 10 °C) is used.
 Check the temperature of the milk.
The central spout with integrated cappucinatore is not
correctly fitted and is taking in air. Of the spouts are
blocked.
 Check the central spout is correctly assembled.
Make sure all parts are securely connected with
each other.
 Clean the central spout if necessary. Knead the
spouts under running water to loosen any soiling.
The milk pipework, connections or the intake tube on
the milk flask are blocked.
 Clean all parts carefully with the cleaning brush.
The steam jet on the central spout has a blockage.
 Clean the steam jet with the cleaning brush (see
illustration).
This is not a fault.
Movement of the brew unit during the brewing
process can cause some coffee to fall. The type of
coffee bean, the type of grind and the amount of
ground coffee has an influence on how much there
is. Important! Clean the area around the brew unit
regularly to prevent the risk of mould etc.
