2. DESCALE

When the drained water in the base tray has white or gray grains in it, the oven needs descaling.

These white or gray grains, also called scale, form in the water circuit inside the oven during steam
generation, which could cause the oven to malfunction. The frequency of descaling will depend on
the hardness of the water that you use; the harder the water the more often descaling will be necessary.
Either when the white or gray grains are seen or when "Descaling necessary" appears in the display,
it is strongly recommended that descaling be done immediately. The descaling process takes about
1 hour and 30 minutes.

Note:
If the electrical power supply is interrupted during descaling, the process is cancelled. Follow the above
example again.

CAUTION:
THE SUPERHEATED STEAM OVEN'S PERFORMANCE MAY BE AFFECTED SHOULD SCALE BE
ALLOWED TO BUILD-UP. DESCALE REGULARLY.

4. Citric acid, available at some drugstores, or bottled lemon

To use citric acid, dissolve 1 tablespoon of citric acid crys-
tals in 2

cups of water in a non-porous container. Stir well

and pour into the reservoir.
To use 100% bottled lemon juice, check that there is abso-
lutely no pulp in it. If there is pulp or you are not sure, strain
through a fine strainer.
