Problem Cause and remedy
The temperature display
lights up but the refri-
geration appliance is
not cooling.
Demo mode has been activated. This allows the refri-
geration appliance to be presented in the dealer
showroom without the cooling system being
switched on. This setting is not needed for domestic
use.
 Switch off demo mode by running the appliance
self-test:
 Switch the refrigeration appliance off.
 Disconnect the power supply.
 After 5minutes, reconnect the refrigeration appli-
ance to the mains and switch it back on.
 Within the following 10seconds, touch the
sensor control for 3–5seconds until an acoustic
signal sounds.
The self-test starts.
- If 2 acoustic signals sound at the end of the self-
test and the temperature display shows the set
temperature, your refrigeration appliance is ready
for operation.
- The refrigeration appliance reverts to normal opera-
tion.
- If 5acoustic signals sound at the end of the self-
test and the temperature display LEDs light up with
varying brightness levels, a fault has occurred.
Contact the Miele Customer Service Department.
The LEDs inform the Customer Service Department
about the fault in question.
The compressor is
switching on more fre-
quently and for longer
periods of time. The
temperature in the refri-
geration appliance is
too low.
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 fre-
quently, 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.
