Your �KO-LAVAMAT is equipped with a particularly efficient water softener, through two-stage addition of water softener and detergent. For washes without a prewash cycle, this allows the separate addition of softener and detergent. This enables a saving in detergent and noticeable improvement in discharge water quality. The two-stage addition ensures that first the water softener is added. Only then is the detergent added, reacts with the softened water and is immediately effective for dissolving dirt. This ensures that wash results are always perfect despite very economical use of detergent. The softener quantity should be added in accordance with water hardness, following the instructions on the softener packet, less 20% which can be saved on account of the optimum effectiveness of the water pre-softening. Detergent in this case should always be in quantities required for water hardness I - �soft� in accordance with the instructions on the packet. You can also use programmes with a pre-wash cycle in an environmentally conscious manner. Add the detergent and softener together in the pre-wash and main wash compartments. Of course, you can also use normal detergent without softener, adding the quantities recommended on the packet in accordance with the degree of hardness of the water.
