The amount of detergent used depends on the size of load, water
hardness and degree of soiling.
Refer to the instructions on the products.
Information on the hardness of water in residential areas can be
obtained from the Local Water Authorities.

If the detergent manufacturer gives no indication of how much
detergent to use for a part load, we recommend that you reduce
the detergent measure by 1 /3rd for a half load and that you use a
half measure of detergent for a minimum load.
The washer-dryer is fitted with a special device for preliminary sof
tening of the water by dispensing the softener and the detergent
in two stages. In programmes without prewash it enables the
softener and detergent to be dispensed separately for increased
saving on detergent, and therefore less water pollution.
Separate dispensing of the two substances means that initially,
only the softener is added to the water. When the detergent is
then added, because the water is already soft, it starts to act
immediately on dirt in the fabrics. This process ensures optirrium
washing results, even with minimum measures of detergent.
Normal water softening agents should be measured out accord
ing to the hardness of the water, following the instructions on the
pack but, because of the preliminary softening device, you may
reduce the quantity by 20%. In this case, always use the amount
of detergent rècommended on the detergent pack for level I
hardness of water (soft).
Even when a prewash programme is selected, it is still possible
to protect the environment. Pour the detergent and water soften
ing agent together into the prewash and main wash dispenser
compartments.
You may obviously continue to use normal detergents without sof
tening agent, using an amount based on the pack recommenda
tions and the degree of water hardness.
