The amount of solution specified can be
more than the amount which is actually
taken in. Some of the solution may
therefore be left in the container at the
end of descaling.
A message will appear in the display
when the intake process is finished.
 Confirm with OK.
The activation phase will begin. You
can follow the duration as it counts
down.
 Leave the container with the tube
connected to the water intake pipe in
the oven. Top the container up with
approx. 300 ml of water, as the
system will need to draw in some
more liquid during the activation
phase.
The system will take in more liquid at
approximately 5 minute intervals. You
will hear the noise of the pump for a
moment or so.
The oven lighting and the cooling fan
will remain on during descaling.
At the end of the activation phase a
buzzer will sound, if the buzzer is
switched on (see "Settings - Volume -
Buzzer tones").
