" What is Drum Washing Machine? 1. Drum Washing Machine Water consumption is reduced by using the power of the laundry falling (free-fall) created when rotating the drum resembling a sieve net. With temperature control system, this drum washing machine saves energy and improves washing performance at the same time. 2. Key Features " Simultaneous supply of cold#hot water As cold and hot water is supplied at the same time, heating time and energy is saved.

rum Wa 4. Major Functions $ Washing When rotating drum after putting in the laundry and detergent into the drum, the laundry are rotated by protrusions (lifters) attached inside the drum. Washing is carried out with bending and impact actions generated by falling of the laundry to the top part of drum. % Rinsing Rinsing cleanly washes out detergent and dirt removed from the laundry after washing cycle. & Spin-drying Weak, standard and strong cycles can be selected according to types of fabrics to be washed.

Extend Wash 1) When button is pressed, washing time increases per washing course, such as by 6 minutes for 'heavily', 8 minutes for 'sanitary', 5 minutes for 'everyday wear' and 'towel' and 4 minutes in other cases. 2) Extra wash is not available in Silk/Gentle, Quick Wash, Wool/Handwash courses. 3) Extra wash LED is turned off when washing is completed. 4-9. Extra Rinse 1) Extra rinse is not available in Quick wash courses. 2) When pressing button rinsing cycle is added by once and LED is lit.
4-10. Night Time 1) When pressing button, spin speed is set as low and interim spin-drying changes from 790 r.p.m. to 550 r.p.m. 2) When pressing button again, set values of interim spin-drying and main spin-drying mode courses are resumed. 3) LED is turned off when the cycle is completed. 4-11. Delay Start 1) Preset time indicates starting time of the entire cycle. 2) When pressing preset button, time changes in the order of 1.2.3. 4 ….12.1.
