Problem solving guide

Many malfunctions and faults that can occur in daily operation can be easily
remedied. Time and money will be saved because a service call will not be
needed.
The following guide may help you to find the reason for a malfunction or a fault,
and to correct it.
To prevent unnecessary loss of temperature it is advisable not to open the door
while waiting for the appliance to be serviced.
Issue
The appliance is not
getting cold, the interior
lighting does not come
on when the door is
opened, and the display
is not lit up.

switching on more
frequently and for

Cause and remedy
The appliance is not switched on and the mains
connection symbol  is lit up in the display.
 Switch the appliance on.
The plug is not inserted in the socket correctly.
 Insert the plug correctly into the socket. The mains
connection symbol  appears in the display
when the appliance is switched off.
Check whether the mains fuse has tripped. There
could be a fault with the appliance, the household
electrical wiring or another electrical appliance.
 Contact your Miele dealer.
This is not a fault. To save energy, the compressor
runs at a lower speed, but for longer, when less
cooling is required.
The ventilation gaps have been covered or become
too dusty.
 Do not block the ventilation gaps.
 Dust the ventilation gaps regularly.
The appliance doors have been opened too
frequently, or a large amount of fresh food has been
put in all at once for storage or freezing.
 Only open the appliance doors when necessary
and for as short a time as possible.
After a while, the temperature will return to normal by
itself.
The appliance doors are not closed properly. A thick
layer of ice may have formed in the freezer section.
 Close the appliance doors.
