Possible cause and remedy
The cup has not been pre-heated.
The smaller the cup and the thicker its walls, the
more important it is to pre-heat it.
Pre-heat the cups, e.g. using the cup heating
function (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 coffee machine needs descaling.
Descale the coffee machine.
The brew unit is blocked.
Degrease the brew unit (see "Cleaning and care -
Degreasing the brew unit and cleaning the
interior").
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.
