. . . there is a build-up of frost on the
front panel of the frost-free system.
This is not a fault. Droplets of
condensate have settled on it and
frozen. This may have been caused by
one of the following:
^ The appliance door has been
opened frequently or left open for a
while.
^ A large quantity of fresh food has
been placed in the appliance at
once.
^ There has been an increase in the
humidity in the room.
Keep the door closed as much as
possible so that the Frost Free system
has a chance to melt the ice droplets
automatically.This may take several
days.
If you still cannot remedy the fault
having followed these suggestions,
please contact the Miele Service
Department.
To prevent unnecessary loss of
temperature it is advisable not to
open the door while waiting for the
appliance to be serviced.
