5. Turn off the oven and let it cool
down.
6. When the oven is cool, clean it with a
soft cloth.
WARNING!
Make sure that the oven
is cool before you touch

burns.
10.6 Cleaning the water tank
WARNING!
Do not put water into the
water tank during the
cleaning procedure.
During the cleaning
procedure, some water can
drip from the steam inlet
onto the cavity of the oven.
Put a dripping pan on the
shelf level directly below the
steam inlet to prevent water
from falling onto the bottom
of the oven cavity.
After some time, you can have lime
deposits in your oven. To prevent this,
clean the parts of the oven that generate
the steam. Empty the tank after each
steam cooking.
Types of water
• Soft water with low lime content -
recommended type. It decreases the
quantity of cleaning procedures.
• Tap water - you can use it if your
domestic water supply has purifier or
water sweetener.
• Hard water with high lime content -
it does not have an effect on the
performance of the oven but it
increases the quantity of cleaning
procedures.
