Problem Possible cause and solution
The coffee is not hot
enough.
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, e.g., using the cup heater
(depending on model).
The brewing temperature is set too low.
Set a higher brewing temperature.
The filters in the brew unit are blocked.
Remove the brew unit and clean it by hand.
Degrease the brew unit.
The heating-up time is
getting longer. The
amount of water being
dispensed is incorrect
and the coffee machine
is not performing
properly. Coffee drinks
trickle/dribble slowly
out of the central spout.
The coffee machine needs descaling.
Descale the coffee machine.
The amount of coffee
dispensed has changed.
The brew unit is blocked.
Degrease the brew unit (see “Cleaning and care –
Degreasing the brew unit and cleaning the
interior”).
The consistency of the
milk froth is
unsatisfactory.
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 and milk pipework with the
brush.
