Troubleshooting and error codes

What to do if... Possible Cause and Solution
... the appliance does not get cool.
  • Make sure the temperature selector is not pointing to the "0" position.
  • Check that the plug is correctly inserted in the socket and switched on.
  • Check that the fuse is not defective and that the mains fuse has not blown. If it has, contact the Miele Service Department.
... the door will not open because it has been opened and closed too many times in succession. This is not a fault. The suction caused by opening and closing the door is preventing the door from opening. Wait a few minutes and then try again. It should now open without force.
... the temperature is too low.
  • Turn the temperature selector to a setting closer to "0".
  • Super freeze has not yet switched itself off. The Super freeze function switches itself off automatically after approx. 65 hours.
... the appliance is switching in too frequently and for too long.
  • Check whether the ventilation gaps have been covered over or become dusty.
  • Check whether the metal grille (heat exchanger) at the rear of the appliance has become dusty.
  • The door has been opened too frequently, or a large amount of fresh food has been put in at once for freezing.
  • Check that the door has been closed properly.
... the alarm sounds and the alarm indicator light flashes. The temperature in the freezer is too warm, because
  • a large amount of food has been frozen at once without switching on the Super freeze function. The alarm will stop and the indicator light will go out when the temperature has reached the correct level again.
  • the compressor is faulty. Call the Service Department.
... the Super freeze indicator light and the temperature display are both flashing at the same time. There is a fault. Call the Service Department.
... the Super freeze indicator light does not light up, even though the appliance is working. The indicator light is defective. Call the Service Department.
food has frozen together. Use a blunt instrument, e.g. a spoon handle or plastic scraper, to prise it apart carefully.
