Problem
Neither milk nor milk
froth comes out of the
central spout.
The milk sputters when
it is dispensed. Hissing
noises can be heard
when milk is being
heated up or frothed.
Although the milk
should be frothed, only
hot milk comes out of
the main dispenser.
A fan can be heard even
though no drinks are
being prepared and the
coffee machine is
switched off.
The display lights up
but the coffee machine
does not heat up and no
drinks are made.
The coffee machine
cannot be switched off.
Possible cause and remedy
The milk pipework is blocked.
 Clean the central spout and milk pipework
carefully with the brush.
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.
The central spout is not fitted correctly and is
drawing in air. Or the spouts are blocked.
 Check whether the central spout has been
assembled correctly. Make sure that all parts are
tightly connected to one another.
 Clean the central spout. Rub the spouts under
running water to loosen any soiling.
The milk pipework, connecting pieces, or the
stainless steel tube of the milk flask are blocked.
 Clean all parts thoroughly with the cleaning brush.
The steam jet on the central spout has a blockage.
 Clean the steam jet with the cleaning brush (max.
1 cm wide).
This is not a fault.
Once a drink has been dispensed or the machine
has been switched off, the internal fan will continue
to run until the interior is sufficiently dehumidified.
The Demo mode of the coffee machine for Miele
Experience Centres and Chartered Agents has been
activated.
 Deactivate Demo mode.
