Unsatisfactory results

Problem
The coffee is not hot
enough.
Drinks are being
dispensed from the
central spout
considerably more
slowly. The heating-up
time is getting longer
and the coffee machine
is not performing
properly.
The consistency of the
milk froth is
unsatisfactory.
The coffee grinder
makes a louder noise
than usual.
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.
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 more
frequently.
 Run the
Descale the machine
programme. You will need one descaling tablet.
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.
The coffee bean container has become empty during
the grinding process.
 Fill the coffee bean container with fresh beans.
There may be foreign objects such as plastic or
stones in amongst the coffee beans.
 Switch the coffee machine off immediately. Call
Miele.
