been covered over or become too
dusty.
^ Check whether, the metal grille (heat
exchanger) at the rear of the
appliance has become too dusty.
^ The doors have been opened too
frequently, or a large amount of fresh
food has been put in at once for
freezing.
^ Check that the doors have been
closed properly.
^ Check whether a thick layer of ice
has built up. If it has then the freezer
will need defrosting.
. . . the alarm sounds and the freezer
section temperature display flashes.
The freezer section temperature has
risen above the temperature set
because
^ the freezer section 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 for the freezer
will light up constantly and the alarm
will go off.
. . . a bar is lit up or flashing in the
temperature displays.
Check the temperature displays about
6 hours after switching on the
appliance. The display will not show a
temperature until the temperature in the
appliance has reached a certain level.
. . . the following messages show in
the temperature display "
F0" to "F5".
There is a fault. Call the Service
Department.
. . . the following message appears in
the temperature display: "nA" .
The freezer section 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
freezer section 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 re-frozen after it has been
cooked.
The warmest temperature will show in
the display for about 1 minute. The
actual current temperature in the
freezer section will then show in the
display again.
