DETERGENTS AND ADDITIVES
Choice of the right detergent and additives
The type of detergent depends on:
•
type of fabric (cottons, easy care/synthetics,
delicate items, wool).
Note:
use only specific detergents for wool.
•
colour;
•
washing temperature;
•
degree and type of soiling.
Notes:
Whitish residues on dark fabrics are caused by
insoluble detergents components used in modern
phosphate-free powder detergents.
If you notice this problem, shake or brush the
affected items or use a liquid detergent.
Keep detergents and additives in a dry place and
out of reach of children.
Use only detergents and additives specifically
produced for domestic washing machines.
If you use descaling agents, dyes or bleaches,
make sure they are suitable for washing machine
use. Descaler could contain components that can
attack parts of your washing machine.
Do not use solvents (turpentine, benzine, etc.).
Do not machine wash fabrics that have been
treated with solvents or flammable liquids.
Dosage
Follow the instructions on the detergent pack in
relation to:
•
the degree and type of soiling;
•
the size of the load:
•
full load: follow the detergent
manufacturer’s instructions;
•
half load: 3/4 the amount used for a full
load;
•
minimum load (about 1 kg): half the amount
used for a full load;
•
water hardness in your area (ask for
information from your water company): soft
water requires less detergent than hard
water.
Notes:
Too much detergent can result in excess foam
formation, and the reduction of washing
efficiency. If the appliance detects excessive foam
it may prevent spinning.
Insufficient detergent may result in: grey laundry,
deposits on the drum, tub and heater.
You can use liquid detergent in the “Prewash”
phase for programmes with this option. In this
case put only powder detergents in the
compartment for the main wash
.
When using concentrated fabric softeners, add
water in the detergent dispenser up to
“MAX”
level
mark.
To prevent dispensing problems when using highly
concentrated powder and liquid detergents, use
the special detergent ball or bag supplied with the
detergent and place it inside the drum.
