2. FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Direct Drive System
The advanced Brushless DC motor directly drives the drum
without belt and pulley.
Tilted Drum and Extra Large Door Opening
The tilted drum and extra large door opening make it possible
to load and unload easily.
Water Circulation
Spray detergent solution and water onto the load repeatedly.
Clothes are soaked more quickly and thoroughly during the wash cycle.
Detergent suds are eliminated more easily by the water shower
during rinse cycle. The water circulation system uses both
water and detergent more efficiently.
Automatic Wash Load Detection
Automatically detects the load and optimizes the washing time.
Built-in Heater
The internal heater automatically heats the water to the optimum
temperature on selected cycles.
Child Lock
The Child lock feature prevents children from pressing any buttons
to change the settings during operation.

2-2. NEURO FUZZY WASHING TIME OPTIMIZATION
To get the best washing performance, optimal time is determined by the water temperature,
the selected washing temperature, and the size of the load.
2-3. WATER LEVEL CONTROL
This model incorporates a pressure sensor which can sense the water level in the tub.
The water supply is stopped when the water level reaches the preset level, the washing
program then proceeds.
Spinning does not proceed until the water in the tub drains to a certain level.

2-4. DOOR CONTROL
The door can be opened by pulling the door handle whenever washer is not in operation.
When the cycle is completed, the DOOR LOCKED light will turn off.
If a power failure has occurred while in operation, the door will unlock after 5 minutes.
Clicking sounds can be heard when the door is locked/unlocked.
2-5. THE DOOR CAN NOT BE OPENED
While program is operating.
During a power failure or if the machine is unplugged while running.
While door Lock lights turn on.
Wile the drum is still turning, even if the machine has been stopped or paused.

2-8. WATER CIRCULATION
2-7. CHILD LOCK
2-6. DOOR LOCKED LAMP LIGHTS
The recirculated water sprays from a nozzle at the top of the door gasket.
During the wash cycle, it runs continuously for the first three minutes and intermittently after that.
During the rinse cycle, it runs continuously after the drum is filled.
When the frequency of water level is lower than 22.9 kHz.
(It can be canceled when the frequency is more than 23.8 kHz.)
When the temperature inside the tub is higher than 45¡C (113¡F) and water level is not 25.5 kHz.
(It can be canceled when the water level is 25.5 kHz or the temperature inside the tub is lower than
40¡C (104¡F))
Use this option to prevent unwanted use of the washer. Press and hold STAIN CARE button for 3
seconds to lock/unlock control.
When child lock is set, CHILD LOCK lights and all buttons are disabled except the POWER
button. You can lock the controls of the washer while washing.
CHILD LOCK remains in effect after the cycle and even if the power is turned off. To UNLOCK,
press and hold the STAIN CARE button for 3 seconds.
2-9. Cycle counter
Select this function to check the number of cycles.
1. Press Power button.
2. Select a cycle.
3. Press Start/Pause button.
4. Press Wash and Rinse button simultaneously, then the
number of cycles will be displayed.
If less than 1000 cycle, the number of cycles is expressed
as is.
If more than 1000 cycle, the number of thousands place
and the remaining numbers appears taking turns.
E.g. in case of 1,020
1 󱈓20 󱈓blank (repeated)
The number of cycles can be reset when Main PCB is replaced.
(It does not change in case of a simple change in the program.)

interval.
- Favorite : Favorite program allows you to store a customized wash cycle for future use.
- Tub clean : This option can remove a buildup of detergent residue can occur in the wash tub over time and can lead
to a mildewy or or musty smell.
- Rinse + Spin : This can be helpful in preventing fresh stains from setting in fabrics.
- Crease Care : If you want to prevent creasing, select Crease Care option
- Beeper : Adjusts the volume of the den-of cycle beeper, or tums it off
