Frequently asked questions
The door to the freezer section will not open.
Possible fault
This is not a fault.
The suction caused by opening and
closing the door too many times in
succession prevents it from opening.
The compressor kicks on very frequently and for too long.
The ventilation slits are covered or
dusty.
The doors have been opened too
frequently, or a large amount of fresh
food has been put in at once for
freezing.
The door is not closed.
The compressor runs continuously.
To save energy, the compressor runs at a lower speed, but for longer, when less
cooling is required. This is not a fault.
The appliance will not turn off.
The safety lock has been activated. (See "Safety Lock".)
The interior lighting of the refrigerator section is not working.
Do not remove the cover. Should the cover be damaged or need to be
removed due to damage, exercise caution. There are lasers in the lighting
(laser beam class 1M) which you should avoid looking at directly. Do not use
optical instruments (magnifying glass or similar) to look at the lighting either.
The refrigerator door has been left
open for too long.
If the lighting does not come on
when the door is opened briefly, but
the temperature display is working,
then the lighting is defective.

Solution
Wait a few minutes, then try again. It
should now open without force.
Clean with a vacuum or brush.
Once the fridge/freezer gets down to the
set temperature the compressor will turn
off.
Check that the doors have been closed
properly.
The lighting turns itself off automatically
after approx. 15 minutes.
Contact Miele Technical Service.
The LED lighting should only be
repaired/replaced by a Miele service
technician. Danger of injury or damage.
