Do not use salt at this level.
Regardless of the type of detergent
used, set the proper water hardness
level to keep the salt refill notification
active.
Multi-tabs containing salt are
not effective enough to
soften hard water.
8.2 The salt container
CAUTION!
Use rough salt designed for
dishwashers only. Fine salt
increases the risk of
corrosion.
The salt is used to recharge the resin in
the water softener and to assure good
washing results in daily use.
How to fill the salt container
1. Turn the cap of the salt container
counterclockwise and remove it.
2. Put 1 litre of water in the salt
container (only for the first time).
3. Fill the salt container with dishwasher
salt (until it is full).
4. Carefully shake the funnel by its
handle to get the last granules inside.
5. Remove the salt around the opening
of the salt container.
6. Turn the cap of the salt container
clockwise to close the salt container.
