Descaling
The following message will appear on the
display from time to time to indicate that you
should carry out the boiler descaling
procedure:
1. Touch the CONFIRM button to start
the descaling function.
2. Fill a jug with a descaling solution (e.g.
dilute citric acid).
3. Open the door completely.
4. Open the oven door.
5. Rest the jug on the open door.
6. Remove the tube from its seat.
The presence of scale due to lack
of descaling can compromise
correct operation of the appliance
in the long term.
We recommend mixing 100 g of
citric acid with 250 ml of water.
Note: Do not use lactic acid.
PLEASE NOTE: overall weight of
the jug containing the descaler
must be less than 5 kg.
