2-2. DETERMINE WASHING TIME BY FUZZY LOGIC
To get the best washing performance optimal time is determined by sensing of water temperature,
selected washing temperature and laundry amount.
If the drain hose is not installed properly, the unit will not drain properly.
This allows water to back flow into the unit which can cause odors.
Refer to Owner Manual for proper drain hose installation.

2. FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Anti Crease function
With the alternate rotation of the drum, creasing in the laundry is
minimized.
More economical by Fuzzy Logic System
FUZZY Logic System detects the amount of load and water
temperature, and then determines the optimum water level and
washing time to minimize energy and water consumption.
Child-Lock
The Child-Lock system has been developed to prevent children
from pressing any button (except Power button) to change the
programme during operation.
Low noise speed control system
By sensing the amount of load and balance, this system
automatically distributes load evenly to minimize the spinning
noise level.
Direct Drive System
The advanced Brushless DC motor rotates the drum directly
without a belt and a pulley.
Built-in heater
Internal heater automatically heats the water to the best
temperature on selected cycles.

This model uses a pressure sensor to determine the water level in the tub.
When the preset water level reached, water supply is stopped and the program proceeds.
Water needs to be below a preset level before spining will proceed.

INSTALLATION
The appliance should be installed as follows.
1 Check the conditions of installation area.
1. Check level ground.
horizontal
On raised foundations or upper level homes, the vibrations can be caused by the type of flooring.
It may be necessary to move the machine to a different area in home or have the floor
reinforced to properly support the operation of the unit.
2. Check humidity or any foreign objects under the feet.
Clean the floor, and there should not be any foreign objects under the feet.
If the unit has foreign objects underneath the feet, this will prevent the unit from being leveled properly
and will cause vibrations and slipping.
Remove any foreign objects, if any from underneath the machine and level unit properly.
See below for examples of foreign objects.

6 Connect Drain Hose.
If the drain hose is not installed properly, the unit will not drain properly.
This allows water to back flow into the unit which can cause odors.
Refer to Owner Manual for proper drain hose installation.
The odor could also be coming from the home’s drain to which the drain hose is attached.

Hose
Retainer
Tie Max. 100cm

Max. 100cm
In this type of drain hose installation, the odor could be coming from the standpipe.
This odor can come up the drain hose and into the unit.
Pour a cup or two of bleach or vinegar down the home drain
and let it sit for 24 hours before running another cycle.
This will help eliminate odor from the home drain.
If a cycle is started too soon after doing this, it will not help the issue.
7 Connect power plug.
Connect the power plug to the wall outlet. Avoid connecting several electric devices,
it may be the cause of a fire.

Place your right hand on the back, right corner and your left hand on the front,
left corner of the unit, then attempt to rock the unit from corner to corner.
Then, move your right hand to the front, right side and your left hand to the
back, left corner and attempt to rock the unit from corner to corner.
If the unit is level, it will not rock. However, if the unit is not level, it will rock.
If the unit rocks, it will be necessary to adjust the leveling feet of the unit.
Adjust the foot under the hand that is on the front of the machine.

To do this, put 2~3kg of clothing in the unit, power on the unit, press the Rinse and Spin
button, and then start. When the unit reaches the spin cycle, watch for vibrations.
If the unit is vibrating, make small adjustments to the leg until they subside. (Try 2Step again)

Motor Locked Error (LE)
[Pre Check]
• Gentle wash cycles, such as Perm Press, Delicates, Hand Wash, and Wool/Silk should only be used for smaller loads.
Because these cycles are more gentle in tumbling and spinning, putting too much in the drum can register an issue
with the motor. Remove items, reset unit and test with a Rinse/Spin cycle.
• Don’t replace the PCB, when the hall sensor is replaced.
Replace the PCB, when the LE is displayed after replacing the hall sensor.
Press the Power button & Start / Pause button.
Does the Drum stop when the start/pause button is pressed to start the cycle ?
Or Sometimes does the Drum rotate weakly (under 15rpm)?
YES

1 Disassemble the Hall Sensor
1) Disassemble the hook of Hall Sensor by (-) driver.
2) Pull up Hall Sensor slowly as shown in picture.
Caution
If you disassemble by force,not following the directions,
the hooks of stator(red circled) might broke up.
Hence need change of stator assembly.
So disassemble cautiously.
2 Assemble the Hall Sensor
1) Adjust the hole of Hall Sensor to 2) Push down the Hall sensor,
the hooks of stator as picture.(red circled) and assemble to the hook for sure.
[Note]
Hall Sensor Part No.

7-6. Using SmartDiagnosis™
SmartDiagnosis™ function is available only for the products with a SmartDiagnosis™ mark.
In case of a mobile phone with static option, the smart diagnosis function might not operate.
• Only use this feature when instructed to do so by the call center.
The transmission sounds similar to a fax machine, and so has no meaning except to the call
center.
• SmartDiagnosis™ cannot be activated if the washer does not power up.
Follow the call center agent's instructions, and do the following steps when requested:
If this happens, then troubleshooting must be done without SmartDiagnosis™.
If you experience problems with your washer, call to Customer information center.
1. Press the Power button to turn on the washer.
Do not press any other buttons or turn the cycle
selector knob.
2. When instructed to do so by the call center,
place the mouthpiece of your phone very close
to the Power button.
3. Press and hold the “Temp.” button for three seconds, while holding the phone
mouthpiece to the icon or Power button.
4. Keep the phone in place until the tone transmission has finished.
This takes about 17 seconds, and the display will count down the time.
• For best results, do not move the phone while the tones are being transmitted.
• If the call center agent is not able to get an accurate recording of the data, you may be
asked to try again.
• Pressing the Power button during the transmission will shut off the SmartDiagnosis™.
5. Once the countdown is over and the tones have stopped, resume your conversation with
the call center agent, who will then be able to assist you using the information transmitted
for analysis at the call to Customer information center.
