Possible cause and remedy
The coffee is too finely ground.
 Set the grinder to a coarser setting (see "Setting
the coffee grinder").
The grinder setting is not correct.
 Set the grinder to a finer or coarser setting (see
"Setting the coffee grinder").
The brewing temperature is too high for this type of
coffee.
 Set a lower brewing temperature (see "Brewing
temperature").
The coffee beans are no longer fresh.
 Add fresh coffee beans to the coffee bean
container.
Possible 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 in the milk flask.
The milk flask has not been fitted correctly and so air
as well as milk is being sucked in.
 Push the milk flask in until it clicks into position.
The central spout is not fitted correctly.
 Check whether the central spout has been
assembled correctly.
The milk pipework in the milk flask lid is dirty.
 Dismantle the milk flask lid and clean it with the
cleaning brush (see "Cleaning and care – Milk
flask").
 Clean the central spout and the milk valve with the
cleaning brush (see "Central spout" and
"Maintenance of the milk valve").
The angled connector is blocked and must be
replaced.
 Replace the angled connector (see "Replacing the
angled connector").
