• 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.
• Also available are tablet detergents which state that that no salt or
rinse aid is required. In some cases, these detergents might not give
good results, especially with short and/or low-temperature washing
cycles.
If performance problems (e.g. a white coating on the tank or dishes,
poor drying, dirt on dishes at the end of the wash) are noted, users
are advised to return to conventional products (granular salt, powder
detergent and liquid rinse aid).
However, please note that on return to the use of conventional salt,
a number of cycles will be required before the system becomes fully
efficient again, so traces of white coating may still be found on the
tank and dishes. If the problem persists for too long, contact the
After-Sales Service.
• When using detergent in tablet form (bear in mind that we
recommend the use of three separate products: detergent, salt and
rinse aid), place the tablets in the cutlery rack. The dispenser is
designed to use powder or liquid detergent and the door does not
open completely during the washing cycle. This means that a tablet
is not completely dissolved (released), which may lead to the
following:
- not enough detergent released during the cycle, with poor washing
results;
- the detergent forms a solid block in the distributor and is released
during the final rinse cycle.
The introduction of detergent into the rinse aid dispenser, even in
liquid form, will damage the dishwasher.
