ADDING THE DETERGENT

After adding the detergent, to close the lid slide it in the direction shown 
by the arrow as far as it will go then press gently to lock. During washing, 
the dispenser will be opened automatically. 

•

Use  only detergents specially formulated for dishwashers. For 
optimal washing results it is important to use a good quality 
detergent.

•

The detergent packs must be sealed and stored in a dry place to 
prevent the formation of lumps which may negatively affect washing 
results. Once opened the detergent packs should not be kept for too 
long, otherwise the detergent loses its effectiveness.

•

Do not use detergents formulated for washing dishes by hand, 
because they produce a great deal of foam and may negatively 
affect the operation of the dishwasher.

•

Add the correct amount of detergent. An insufficient amount of 
detergent will result in a partial removal of dirt from the dishes, 
whereas an excessive amount is wasteful and does not improve the 
washing results. 

•

The market offers liquid and powder detergents with differing 
chemical compositions, which may contain phosphates, or be 
phosphate-free but contain natural enzymes. 

- Detergents containing phosphates are more effective against 

grease and starch at temperatures above 60°C. 

- Enzyme detergents, on the other hand, are also effective at lower 

temperatures (from 40 to 55°C) and are more easily 
biodegradable. With enzyme detergents it is possible to obtain at 
low temperatures comparable results to those which can only be 
achieved at 65°C using traditional detergents.  

For the safeguarding of the environment we recommend the use of 
phosphate- and chlorine free detergents.
