Smeg DWD409SS, DWD409WH instruction manual Grease and starch at temperatures above 60C

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.

•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.
