4.2 Using the rinse aid and detergent dispensers
The detergent
dispensers are situated on the inner
part of the door: the detergent
dispenser is on the left, and the
rinse aid dispenser is on the right.
With the exception of the SOAK program, before every washing cycle it
is necessary to add the required amount of detergent to the detergent
dispenser. The rinse aid, on the other hand, should only be added as
required.
