Problem Solving Guide - Miele KFN 7734 F Operating Instructions Manual

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.
Problem
The refrigeration appli-
ance is not getting cold
and the interior lighting
does not come on when
the appliance door is
opened.
The compressor runs
continuously.
The compressor is
switching on more fre-
quently and for longer
periods of time. The
temperature in the refri-
geration appliance is
too low.
Cause and remedy
The refrigeration appliance is not switched on and
the  symbol is lit up on the display.
 Switch the refrigeration appliance on.
The plug is not inserted in the socket correctly.
 Insert the plug into the socket. If the refrigeration
appliance is switched off,  will appear on the
display.
The mains fuse has tripped. There could be a fault
with the refrigeration appliance, the household elec-
trical wiring or another electrical appliance.
 Contact a qualified electrician or the Miele Cus-
tomer Service Department.
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 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.
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.
