This washing machine performs the washing and dehydration functions by rotating its drum around a 10° inclined axis of rotation to the horizontal axis.

1. Washing

The washing technique employed is to let the clothing fall from the top of the drum cycle.

2. Dehydration

The dehydration technique employed squeezes the water out using centrifugal force which pushes the clothing out towards the wall of the drum through the high speed rotation of the drum. (Max 1200 RPM)

3. Drying

Condensing System: This heats the internal and evaporates the moisture contained in the laundry into steam and further uses the condenser to condense the steam before draining, resulting in a temperature decrease inside the drum.

This is easy to install as this does not require a separate duct.

Reference 1. Un-Balance Sensing

The maximum rpm (600, 800, 1000, 1200rpm) for the main dehydration cycle is determined bythe result of the Unbalance Sensing. And if the result of the Unbalance Sensing goes beyond the set value, it performs a re-operation. The restart of the operation begins from the clothes-untwisting cycle after pausing the Unbalance Sensing. For wash and rinse cycles (Unbalance Sensing) If an Unbalance is sensed at a low speed, it performs the Unbalance Sensing a max. of 10 times. And if sensed at a high speed, it does a max. of 5 times. If Unbalance is over the set value thereafter, it performs the next cycle without performing dehydration. For the final dehydration cycle (Unbalance Sensing) If Unbalance is sensed at a low speed, it performs Unbalance Sensing a max. of 10 times. And if sensed at a high speed, it does a max. of 5 times. If Unbalance is over the set value thereafter, the water is supplied during the dehydration cycle to perform the cloth-untwisting cycle a max. of 3 times. However, in a case where 'Unbalances' exceed 3 times, an UE Error is displayed. If there are no 'Unbalances' during the dehydration cycle, it directly performs dehydration regardless of the intermediate stages such as dehydration during washing/rinse and final dehydration.

At Stop / Acceleration

Unbalance

The centers of gravity for both 'Unbalance' and 'liquid balance' face downward.

At constant speed

The centers of gravity for both 'Unbalance' and 'liquid balance' at a speed faster than the resonance point face in the opposite direction, so that it functions in a way to remove the unbalance.

Reference 2. Liquid Balance

- Principle of Liquid Balance The previous drum-type washing machines used to control 'Unbalances' on the principle of weight so that the weight of the product was quite heavy, whereas this product decreases the weight by employing a liquid balance..

3) Water Supply Function

①

When selecting Wash

-. Water is supplied through cold water + hot water(option) valves to the frequency level of the wash set up for each course. (The hot-water valve does not operate when the temperature is set to below 60℃.) If the wash temperature is set to over 40℃for each course, it supplies water to the set-up level and performs a Wetting Cycle and then starts the Heating cycle.

-. When the water level decreases during the Wetting Cycle after the end of the water supply, it supplies water using a supplementary water-supply function. (Except for the Wool and Lingerie courses)

-. Conditions of the Hot-Water Supply (Option)

●

For a temperature setup of over 60℃the cold/hot water valves operate at the same time.

●

Both cold and hot water are used for steering the water level and as supplementary water.

4) Drying Function

① When the drying function starts, the heater, fan/M, drying water supply and drainage motor

perform their operations, running the washing motor using a stream of water.

② The drying cycle is processed in the order below:

- Detection of Drying Amount

- Primary Drying: Operates the 2000W heater (2 1000W heaters)

- Secondary Drying: Operates the 1000W heater

- Ventilation: When the drying cycle is done with dryness sensing, the washer turns off the heater and only runs the fan motor, lowering the temperature inside the drum. All cycles are completed when the temperature of the internal sensor (air sensing) is below 70℃ (60℃ inside of the drum).

③ Dedicated Drying Course Algorithm

a. When selecting Dedicated Drying, the drying cycle starts to operate and completes

its operation once cooling has ended.

b. During the initial drying operation, if the water level goes over a certain level,

pre-heating is added before dehydrating. When selecting a drying time, the washer enters the drying cycle directly without sensing the dry amount. When select a drying option, drying is performed after twice sensing the dry amount.

c. If pre-heating is added to dehydrating, the display time increases by 17 minutes. d. Selecting the Drying Time does not require detecting the drying amount while the

Drying Option does require detecting the amount twice when the remaining time is displayed.

④ Algorithm when adding Drying to normal courses

a. The drying feature can be added to courses other than wool, lingerie, quilt and

drum washing.

b. When drying is added, the last dehydrating cycle is converted from normal to pre-heat.

When all normal cycles are done before the drying process starts, the washer senses the drying amount to reset the drying time and displays the remaining time. (For Drying added by the Drying Option)

5) SOFT KEEP ① When all cycles are done along with Drying, the END feature starts to operate. Once this is

completed, if you do not remove the laundry, the washer rotates the drum in reverse to avoid

wrinkles. ② The reverse-rotation continues up to 30 minutes after the completion of all cycles. ③ The SOFT KEEP time does not belong to the total washing time. ④ When all cycles are done, the END MELODY is performed and the door lock is switched off.

(However, the door stays locked while the tube is running)

⑤ When opening the door while rotating, all motor and display functions stop operating and

turn off.

⑥ While the Soft Keep feature runs after the washer performs all cycles and the first End

Melody function, the End Melody feature operates every ten minutes and the End message is continually displayed.

⑦ The rotating direction of the motor is displayed in the same way as that of the drum while

the washer performs Soft Keep.

⑧ No operating keys are activated and even if pressed, they are automatically switched off

while in Soft Keep.
