ALARMS
Normal use of the freezer may give rise to various disruptions with
unstable cabinet function as a consequence. These disruptions are
shown on the display by means of an alarm code (an “E” followed
by a number) and signalled by the acoustic alarm. In case of
several faults, the alarm codes will be displayed in turn.
Alarm codes
E2 - temperature sensor fault in the freezer’s chamber
A temperature sensor has been damaged. Call your supplier. A
built in emergency program attempts to maintain an acceptable
temperature until the fault is corrected.
E4 - door is open
The door of the freezer’s chamber has been opened for more than
2 minutes. The alarm code disappears when the door is closed.
E5 - temperature too high
The temperature in the freezer has been higher than the set
temperature for more than 2 hours.
E6 - temperature too high at power failure
There has been a power failure, the power to the freezer has been
disconnected or the temperature in the freezer has been higher
than the set temperature for more than 2 hours after power failure.
Interrupting an alarm
The acoustic alarm can always be interrupted by opening the door
and pressing any button. The alarm code will remain displayed
until the alarm has been cancelled. A 2 hour silence will follow.
The alarm codes E4, E5, E6 can be cancelled by pressing for 7-8
seconds simultaneously, the buttons
(6) and (7).
The exception: in case of the alarm E2 it is possible to cancel the
alarm only after replacing damaged sensors.
In such cases please contact your supplier.
