In case of hard water add detergent according to the Chart for degree 1 and add appropriate quantity of water softener (see manufacturer’s instructions).

If you do not apply the program which includes the pre-wash feature, you may add washing detergent directly into the drum.

If you use thick liquid softener it is recommended to dilute it with water, to prevent clogging of dispenser compartment ducts.

Washing machine is equipped with the dispenser partition gate, so you may pour liquid detergent also into the central compartment. If you use powder detergent the gate is lifted up, and in case of liquid detergent it is slid down.

Liquid detergents are intended for main wash only, without pre-wash.

Insert particularly delicate linen (stockings, delicate female underwear, etc.) into the special bag.

High spin RPM leave less moisture in laundry which dries out much quicker in the tumble dryer, thereby saving energy.

Do not put clods of detergent into the soap dispenser as the tube in the washing machine may clog.
