Salt
The hardness of water varies from place to place. If hard water 
is used in the dishwasher, deposits will form on the dishes 
and utensils.
The appliance is equipped with a special softener that uses a 
salt specifically designed to eliminate lime and minerals from 
the water.
Loading the salt into the container
Always use salt intended for use with dishwashers.
The salt container is located beneath the lower rack and 
should be filled as follows:
1.
When the low salt indicator (Fig.2-3) lights, you must fill 
the salt. Remove the lower rack and then unscrew and 
remove the cap from the salt container.
Note: If you are filling the container for the first time, fill 
it with water.
2.
Place the end of the funnel (supplied) into the hole 
and introduce about 2 kg of salt. It is normal for a small 
amount of water to come out of the salt container.
3.
Carefully screw the cap back on.
IMPORTANT: To prevent the formation of rust, load the salt 
just before beginning a wash cycle.
Adjusting salt consumption
The dishwasher is designed to allow for adjusting the amount 
of salt consumed based on the hardness of the water used. 
This is intended to optimize and customize the level of salt 
consumption so that it remains at a minimum.
To adjust salt consumption:
1.
Unscrew the cap from the salt container.
2.
There is a ring on the container with an arrow on it 
(Fig.2-4).
3.
If necessary, rotate the ring in a counter-clockwise 
direction from the ‘–‘ setting towards the ‘+’ sign, based 
on the hardness of the water being used.
We recommend that you adjust the salt consumption in 
accordance with Table 2-1.
The default setting of the water softening system is:
• 
If using multi-functional tablets fill the salt dispenser 
and set the adjuster to ‘–’;
• 
If the hardness of the water is greater than 60°fH, set it 
to ‘+’.
