Cleaning the exhaust pipe
When a cleaning procedure has been cariied out, carefully
wash the exhaust pipe in warm soapy water. Don't use
acids, spray cleaners or abrasives to clean the exhaust
pipe and connectors, this could damage them.
Cleaning the steam generator
Cleaning the water tank
Just like in any appliance fed with water (e.g. the iron), is
it absoluitely normal that limestone residues form in the
water tank.
After having used the oven for steam cooking several
times, the limestone residues that settle inside the water
tank can cause a reduction of the steam.
If the red pilot light that indicates the need of a cleaning
cycle comes on, this means that a certain quantity of
limestone has settled in the water tank and that a
thorough cleaning of the steam generator is necessary.

In that case proceed as follows:
- Set the water tank exhaust-pipe ready for use. Fit
the connector with hexagonal nut (Figure 18, letter
"A") to one of the edges of the pipe.
- Open the oven door (Fig. 19) and fit the connector (A)
into the exhaust-valve (C) located in the lower left hand
corner of the oven cavity frame.
- Place the free edge of the pipe into a vessel, then
turn the pipe connector "A" anticlockwise to open
the exhaust-valve. Water will flow out the water tank.
- When water stops flowing out the water tank, turn the
pipe connector clockwise to close the exhaust-valve.
Warning! - The connector "A" has not a block
fitting. Take care this connector doesn't slip
off the pipe during the water tank exhaust
procedure.
- After the water tank has been drained, melt two
spoonful of citric acid (about 50-60 grams) into 800
cc. of water.
Citric acid
is a natural substance, which looks like white
small grains of sugar. It is normally used in food industry
and can be purchased in drugstores, wine shops or
chemist's shops.
- Pour the citic acid and water solution into the water
tank drawer, as previously explained.
- Fit the connector "B" to one of the edges of the
exhaust-pipe, then insert the connector "B" into the
steam injector (Figure 20, letter "D"). Place the free
pipe edge in a vessel, to collect the limestone
residues.
- Let the citric acid and water solution stay into the
water tank for about 60 minutes, with the oven cooled
down.
- After 60 minutes, switch on the oven by turning the
function control knob on the "STEAM COOKING"
function (symbol:
) and set the thermostat knob
on 140° C.
- After about 20-25 minutes, turn the knobs off.
- Allow the oven to cool down, then drain the water
tank following the procedure previuosly explained.
- When the procedure is carried out, rinse the water
tank by pouring water into the tank drawer and letting
the water flow out through the exhaust pipe, until you

see clear water without limestone residues coming
out.
While carrying out this procedure, a lemon flavour will be
smelt in the room.
If you foresee not to use the steam oven for 2-3 weeks, we
recommend to drain the water tank.
