- After having emptied the water from the tank,
prepare a solution with 800 cc. of water and
50 - 60 grams (two heaped teaspoons) of
citric acid.
Citric acid is a nutritionally approved
substance; and comes in small white
granules similar to sugar. It is usually used
in the food industry and may be purchased
from shops selling
wine , in well-stocked
grocery shops and also in some chemists .
- Pour this solution into the loading drawer.
- Allow the citric acid solution to rest in the tank
for about 60 minutes, in a cold oven.
- Turn the oven on and select the steam function
with a temperature between 130°C and
230°C. After 20-25 minutes, switch it off.
- Allow the oven to cool, then proceed with the
removal of the tank contents following the
procedure described earlier.
- Once the operation is completed, rinse the
tank a few times, pouring the water from the
load drawer and allowing it to flow out of the
outlet probe, until the water coming out no
longer shows any lime residue. Remove any
lime residue from the inside of the oven with a
cloth.
Tank cleaning
As with all apparatus that use water (for example,
irons), it is entirely normal that lime deposits should
form in your oven. After having used it for steam
cooking a number of times, the lime deposits inside
the tank and may cause a reduction of the steam
itself. After about 6 months of operation it is likely that
a certain quantity of lime will have deposited. It is
therefore advisable to proceed with a thorough
cleaning of the parts of the oven that generate the
steam.
In which case, proceed as follows:
Empty the tank as described on page 38.
)
During this operation, the oven and the surrounding
area will be filled with the typical lemon scent. If you
don’t envisage using the oven for a period of more
than 2-3 weeks, we suggest you empty the water
residue remaining in the oven tank.
Cleaning the discharge probe
At the end of each cleaning operation, clean the
probe thoroughly. It can be washed by hand in
luke warm water with usual “dish washing”
detergents. Do not use acids, sprays, or similar
substances on the parts of the steam probe so as
not to zdamage it.
Advice on the various different types
of water
If one uses natural mineral waters, or at least waters
with a low lime content, the cleaning cycles can be
drastically reduced (for example, every 100, 150
uses). If your domestic water supply is equipped
with a purifier or water sweetener, then tap water
may be used without any problems.
The use of harder waters (meaning waters
with a high lime content) leads to the
cleaning operations having to be
performed more often but it doesn’t
jeopardize in any way the overall
performance of the equipment.
