•  When a program with hot prewash is selected (see program table in the “De-

scription of Controls” manual), extra detergent must be placed in the cavity (ref. 

A or B fig. 5-04, depending on models).

•  Only use dishwasher-specific detergents. For optimal washing results it is impor-

tant to use a good quality detergent.

•  The detergent packs must be sealed and stored in a dry place to prevent the for-

mation 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 compo-

sitions, which may contain phosphates, or be phosphate-free but contain natu-

ral enzymes.

•  Detergents containing phosphates are more effective against grease and starch 

at temperatures above 60°C (140°F).

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

(from 40 to 55°C / from 104 to 131°F) and are more easily biodegradable. With 

enzyme detergents it is possible to obtain at low temperatures comparable re-

sults to those which can only be achieved at 65°C (149°F) using traditional de-

tergents. For the safeguarding of the environment we recommend the use of 

phosphate- and chlorine-free detergents.
