Dishwasher - Dual Detergent Dispenser

Dishwashers clean dishes with chemical (through use of a detergent) as well as mechanical (water pressure) wash action.

Detergent is automatically released from the main (closed) detergent cup at the right time in the wash cycle for cleaning. Some dishwashers have two dispenser cups give you the choice of one or two detergent washes, depending on the amount of soil and the hardness of the water. If detergent is placed in the auxiliary (open) cup, it will be dispensed and used during the first fill, acting as a "pre-wash".
