To remove mineral deposits that remain on the oven bottom after using the steam mode, use a cloth or sponge soaked in vinegar or a weak citric acid solution. For more stubborn or extensive scaling, use the Descaling function.
Use the Descaling function after every 2-3 uses of steam mode.
Use this function to remove the white deposits that form after the steam generator is used for a long period.
The Descaling function runs for 1 hour 43 minutes. Water will come out of the steam generator while it is being cleaned.
For instructions on removing and filling the water tank, see "Using the Water Tank."
After a power failure, the Descaling function will resume automatically even if the Rinsing function was running.
If water remains on the oven bottom after descaling, see the instructions under "Using Draining Function" for residual water inside the steam generator.
After running the Descaling function, clean the water tank.
Fill the water tank with a premixed 50:1 mixture of water and citric acid. For example, use 4 tsp of citric acid in 4 1/4 cups water (20 g citric acid in 1000 ml water).
Carefully insert the water tank into correct position in the control panel, making sure to keep the tank level while carrying it. If the tank is not kept level, water will drain out of the tubes in the back.
Press Cleaning in the Main Menu screen. Press Steam Maintenance, then press Descaling.
After 1 hour 32 minutes of descaling, a popup will appear in the display. Following the instructions, drain the tank and fill it with clean water.
Insert the tank and start the Rinsing function. The Rinsing takes about 11 minutes.
Once the Rinsing function is complete, dry the inside of the oven with a soft cloth. Leave the oven door open and allow the oven to dry completely.
