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 cup, for example, with hot water.
The brewing temperature has been set too low.
 Set a higher brewing temperature.
The filters in the brew unit are blocked.
 Remove the brew unit and clean by hand
 Degrease the brew unit.
The coffee machine needs descaling.
 Descale the coffee machine.
The central spout has a blockage.
 Clean the coffee pipework (see "Cleaning and care
- Rinsing the machine).
 If there is still no coffee coming out, or coffee is
only coming out of one side, clean the dispensing
spouts with the cleaning brush.
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 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.
