• 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. 5-06, 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 insuffici t 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.
