Cause and remedy
The cup has not been pre-heated.
The smaller the cup and the thicker its sides, the
more important it is to pre-heat it.
 Pre-heat the cups, e.g. using the cup heating.
The brewing temperature has been set too low.
 Set a higher brewing temperature (see "Brewing
temperature").
The filters in the brew unit are blocked.
 Remove and clean the brew unit by hand (see
"Cleaning and care – Brew unit").
 Degrease the brew unit (see "Cleaning and care –
Brew unit").
The coffee machine needs descaling.
 Carry out the
Descale the machine
programme. You will need one descaling tablet.
If you use hard water (> 20 °dH / 3.6 mmol/l) or if the
coffee machine is used intensively, it may be
necessary to descale the machine manually in
addition to automatic descaling.
Manual descaling: it may be necessary to descale the
coffee machine more frequently in areas with very
hard water.
The milk temperature is too high. Good milk froth can
only be achieved when cold milk (below 10°C) is
used.
 Check the temperature of the milk in the milk flask.
The milk pipework is blocked.
 Clean the central spout with integrated
cappuccinatore and the milk pipework with the
cleaning brush supplied.
