4.2 Using the rinse aid and detergent dispensers
The detergent and rinse aid 
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.
