. . . there is a thick layer of ice in the
freezer.
^ Check whether the door closes
properly.
^ Defrost and then clean the freezer.
A layer of ice that is too thick reduces
efficiency and increases energy
consumption.
. . . the alarm sounds and the
temperature display flashes.
^ Has the appliance door been open
for longer than 60 seconds?
If this is not the case, then the freezer
temperature has risen above the
temperature set because
^ the door has been opened too
frequently, or large amounts of fresh
food have been put in at once for
freezing.
^ the ventilation gaps are blocked.
^ there has been a lengthy interruption
to the power supply.
Once the problem has been resolved,
the temperature display will light up
constantly and the alarm will stop.
. . . a bar is lit up or flashing in the
temperature display.
Check the temperature display about 6
hours after switching on the appliance.
Only temperatures within the range the
appliance can display will be shown. If
the temperature is not within this range,
a bar will be displayed instead.
Problem solving guide
. . . "F0" to "F9" appear in the
temperature display.
There is a fault. Call Miele.
. . . "nA" appears in the temperature
display.
The temperature has risen too high at
some point during the last couple of
days because of a power cut.
^ Press the alarm button whilst "nA" is
lit up in the display.
The temperature display will show the
warmest temperature recorded in the
appliance during the power cut.
Depending on the temperature
displayed, you should check the
condition of food in the freezer. If it has
defrosted or started to defrost, check
that it is still safe to use and, if so, use it
as soon as possible. Defrosted food
may only be refrozen after it has been
cooked.
The warmest temperature will appear in
the display for about 1 minute. The
actual current temperature in the
freezer section will then appear in the
display again.
At the end of a power cut, the
appliance will start operating again at
the last temperature setting selected.
. . . the SuperFreeze indicator light
does not light up, even though the
appliance is working.
The indicator light is defective. Call
Miele.
