Problem Possible cause and remedy
The coffee is not hot
enough.
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 cup, for example, with hot water.
The brewing temperature has been set too low.
Set a higher brewing temperature (see "Brewing
temperature").
The filters in the brew unit are blocked.
Remove and clean the brew unit by hand (see
"Cleaning and care – Brew unit").
Degrease the brew unit (see "Cleaning and care -
Brew unit").
The heating-up time is
getting longer, the
amount of water being
dispensed is incorrect
and the coffee machine
is not performing prop‐
erly.
The coffee machine needs descaling.
Descale the coffee machine (see "Descaling").
Coffee is not being dis‐
pensed from both
spouts evenly. Milk may
be sputtering when be‐
ing heated up.
Coffee deposits in the central spout are obstructing
dispensing.
Dismantle the central spout and clean the compo‐
nents – with the exception of the stainless steel
cover – in the dishwasher (see "Cleaning and care
– Central spout").
The central spout should be cleaned once a
week.
The coffee grinder
makes a louder noise
than usual.
The coffee bean container has become empty during
the grinding process.
Fill the container with fresh beans.
There may be stones in amongst the coffee beans.
Switch the coffee machine off immediately. Call
