User instructions

• 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.
• "3/1" Products
If you wish to use detergents which already contain salt and rinse
aid, check whether your dishwasher is fitted with the "3/1 option
button" on the "Controls description" page and then refer to the
section which explains how to use this function.
If the button is not provided, we recommend the use of conventional
products (separate detergent, salt and rinse aid), because with
conventional washing cycles "3/1" products might create problems
such as a white deposit, poor drying results and residues left on
dishes.
The introduction of detergent into the rinse aid dispenser, even in
liquid form, will damage the dishwasher.
