If your model have not water softener, you may skip this section.

There are two ways to reduce the water hardness: one way is using water softener, the other is using detergent.

The hardness of the water varies from place to place. If hard water is used in the dishwasher, deposits will form on the dishes and utensils.

The appliances is equipped with a special softener that uses a salt specifically designed to eliminate lime and minerals from the water.

Always use salt intended for use with dishwashers.

The salt container is located beneath the lower rack and should be filled as follows:

1 Remove the lower basket and then unscrew and remove the cap from the salt container.

2 If you are filling the container for the first time ,fill 2/3 of its vol ume with water.

3 Place the end of the funnel(supplied) into the hole and introduce about 2kg of salt .It is norm al for a small amount of wat er to come out of the salt container

4 Carefully screw the cap back on.

1. The salt container must be refilled when the salt w arning li ght comes on. Though the salt container is filled enough, t he indicator light may not black out before the salt fully dissolve.

2. If there are spills of the salt, a soak program could be run to wipe them out.

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 the salt consumption could be set proceed as follows:

Unscrew the cap from the salt container.

There is a ring on the container with an arrow on it (see Figure to the side), if necessary, rotate the ring in the anticlockwise directi on from the "-" Setting

toward the "+" sign, based on the hardness of the water being used.It is recommended that adjustments should be made in accordance with the following schema:
