8-6. DISPENSER
The dispenser drawer is a multi-chambered reservoir that allows the user to add all the appropriate
laundry additives before starting the cycle. It has a place for pre-wash and Main wash detergent, fabric
softener, and bleach. Powdered or liquid detergents may be used, but softener and bleach must be
liquids.
Detergents should carry the HE designation. Do not use regular detergents in the washer or overusing
will occur. Regular detergents also cause a scum build-up in the tub, which leads to poor performance
and a foul odor.
