7.11.1 "Blending" function
This function is performed inside the fill tank during the water fill phase. Depending on the position
of the selector, softened water is automatically blended with the unsoftened water present in the appliance.
The softened water is introduced from the softening system into the sump, while the unsoftened water flows
(through the open by-pass valve) directly into the tank through the steam venting ring.
When the regeneration system is set to levels [1-4], it is advisable to activate the BLENDING
function to mix softened water with unsoftened water.
This function optimises the consumption of salt, thus preventing corrosion of glassware when the
water is very soft.
When the BLENDING function is activated, the percentage of
unsoftened water introduced into the dishwasher is 15%.
The BLENDING function is activated using the selector knob located
inside the tub, on the left side, in the vicinity of the steam venting grille:
Position of selector
position 1 = blending enabled
position 2 = blending disabled
8 DRYING
In these dishwashers, the dishes are dried by a steam condensation process. This drying system is
based on the natural circulation of the hot air produced during the hot rinse, when steam circulates inside
the condenser on the fill tank.
The condenser is a (cold wall) condensation chamber filled with water, against which the hot air is
ducted. This contact between the hot air and the cold wall generates a process of condensation.
The type of drying system can be either "activ-dry" or "turbo-dry", depending on the model of
machine.
8.1 "Turbo-dry" drying
On some models, a forced-air drying system is used. Steam is drawn in by a fan inside the upper
duct and then ducted towards the condenser in the fill tank, from where it returns to the tub via the steam
venting ring.
The fan motor (MV) is powered by the triac (connector D3 on the main board) through the start
switch (PU) and the door switch (IP).
The drying time is variable and pre-defined for each washing cycle.
In some programmes, the fan operates for around 20 minutes after the end of the cycle. It shuts off
(and will not restart) when the door is opened.
