• If the water tank does not slide in as smoothly as
it should, clean the bottom of the tank.
Hard Water Scale
If hard water is used in the water tank, the steam
generator may become clogged with hard water
scale. In areas with hard water, run the Descaling
function frequently or use softened water.

Using Descaling Function

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.
NOTE
• Use the Descaling function after every 2-3 uses
of steam mode.
Descaling
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."

resume automatically even if the Rinsing
function was running.
