•  The temperature of the water impacts the effectiveness of all laundry additives and therefore, the cleaning
results. We recommend temperatures of:
- HOT 49~60°C…(120-140˚F)
White items, diapers, underclothing and heavily soiled, colorfast items.
- WARM 29~40°C…(85-105˚F)
Most items
- COLD* 18~24°C…(65-75˚F)
Only very bright colors with light soil.
•  When washing in cold water additional steps may be needed:
-  Adjust detergent amount and pre-dissolve detergent in warm water
-  Pretreat spots and stains
-  Soak heavily soiled items
-  Use appropriate bleach
* Temperature below 18°C…(65˚F) will not activate laundry additives and may cause lint, residue, poor cleaning,
etc. In addition, detergent manufactures and care labels define cold water as 26~29°C…(80-85˚F). 
If the temperature of the water in the tub is too cold for your hands, the detergent will not activate and clean
Using Detergent 
Follow the detergent package directions. Using too little detergent is a common cause of laundry problems. 
Use more detergent if you have hard water, large loads, greasy or oily soils or lower water temperature. 
Choosing the right detergent
We recommend the use of domestic detergent, (powder, liquid or concentrated). Soap flakes or granulated
soap powders should not be used in your washing machine. When washing woolens remember to use
detergent suitable for washing woolens. 
Water temperature 
Using Water 
• The machine sets the appropriate temperature automatically according to the wash program .
• You can change the water temperature by pressing the WATER TEMP button. 
• This machine detects the quantity of laundry automatically, then sets the water level and
proper amount of detergent. 
• When you select a wash program, the water level and amount of detergent (to be used)
will be shown on the control panel.
• The following table shows the amount of water. 
• When the water level is automatically detected, it may differ depending on the quantity of laundry even
though the same water level is indicated on the control panel.
• The amount of a cup in the diagram is about 40g for concentrated detergent.
Amount of Water Level
If iron is present in the water the clothes may become an all-over yellow or they may be stained with brown
or orange spots or streaks. Iron is not always visible. Installation of water softener or an iron filter may be
necessary for severe cases.
