Miele CM 7550 CoffeePassion Operating Instructions Manual page 91

Problem
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 central spout.
The display lights up
but the coffee machine
does not heat up and no
drinks are made.
The coffee machine
cannot be turned off.
Cause and remedy
The milk temperature is too high. Good milk froth can
only be achieved with cold milk (< 10 °C).
 Check the temperature of the milk.
The central spout is not fitted correctly and is taking
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. Knead the spouts under
running water to loosen any soiling.
The milk pipework, the connecting pieces or the
stainless steel tube of the milk container are blocked.
 Clean all parts carefully 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).
The Demo mode for demonstrating the coffee
machine in the showroom has been activated.
 Deactivate Demo mode.
