OTHER CONVENIENT FEATURES 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. 1. Press INFO twice. X2 MAINTENANCE 1. DRAIN WATER 2. DESCALE 3. OVEN CLEANING 2. Press the AUTO dial to confirm. AUTO 3.
