Descaling
The presence of scale due to lack
of descaling can compromise
correct operation of the appliance
in the long term.
The message
periodically appear on the appliance's
display, notifying you that it is necessary to
perform descaling of the evaporation tray
on the base of the oven.
1. Open the door completely.
2. Pour approximately 250 ml of white
vinegar into the evaporation tray, thus
also covering part of the base of the
oven.
3. Press the confirmation knob to start the
descaling function.

5. Use a dish sponge on softened
encrustations in order to remove the
largest possible quantity of scale.
6. When you have finished cleaning, close
the door again.
We recommend performing
descaling every time this is
indicated on the display in order to
keep the boiler in perfect
operating condition.
If you wish to skip the descaling
process, hold down the
confirmation knob for a few
seconds.
Note: The descaling process can
be skipped three consecutive
times. After this, the appliance will
not allow you to run any other
function until the descaling process
is performed.
