Problem
A humming sound can
be heard after switching
on the appliance, during
operation and after
switching off the
appliance.
After moving house, the
appliance no longer
switches from the
heating-up phase to the
cooking phase.
During operation an
unusually large amount
of steam escapes or
steam escapes from
parts of the steam oven
where it does not
usually.
A whistling sound is
heard when the
appliance is switched
on again.
The  symbol appears
in the display and an
audible tone may
sound.
The  symbol and a
number between  and
 appear.
The descaling time and
 flash.
Possible cause and remedy
This is not a fault. It is made by water being pumped
through the system.
Altitude affects the boiling point of water. If you move
house, the appliance will need to be reset for the new
altitude if this differs from the old one by more than
300 m.
 To adjust the boiling temperature, you need to
descale the steam oven (see "Cleaning and care –
Descaling the steam oven").
The door is not properly closed.
 Close the door.
The door seal is not correctly fitted.
 If necessary, press it in all the way round the door
to make sure it is fitted evenly.
The door seal is damaged, e.g. cracked.
 Call Miele.
When the door is closed, the pressure has to
equalise, which can cause a whistling sound. This is
not a fault.
The water container has not been pushed into the
appliance properly.
 Remove the water container and push it back in so
that it connects.
There is not enough water in the water container. The
water level must be between the two marks.
 Fill the water container
The appliance needs to be descaled.
 Descale the steam oven (see "Cleaning and care –
Descaling the steam oven").
