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.

DETERMINATION
2-3. WATER LEVEL CONTROL
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.

4. INSTALLATION
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 the 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.

More than 2cm
If the distance is less than 2cm,
the water supply hose will
kink or fold.

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.

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.

Connect power plug.
Connect the power plug to the wall outlet. Avoid connecting several electric devices,
it may be the cause of a fire.

If washing machine legs are loose or not screwed, then screw up with the spanner wrench.
Using the level, level the washing machine from front to back and side to side.

2 Step
Using the spanner wrench to adjust leg for horizontality and try for Diagonal test.
Diagonal test
How to perform a diagonal test:
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.

Perform a Rinse and Spin with some clothing in 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)

3. No water shortage. 4. No water supply hose leakage.
5. No the inlet filter clogged.
Is the water tap closed?
YES
NO
When there is water in the tub,
is the water level frequency
over 25.5KHz?
YES
NO
Is the Connector connected correctly to
the Main PCB and the Inlet Valve?
Or is the Harness alright ?
Check the Water tap and open it fully.
Check the Air Chamber and the Tube (clogged)
And When you check the water level frequency again,
if it is over 25.5KHz, you replace the Pressure switch.
Reconnect or repair the Connector.
NO
Or replace the Harness.

Unbalanced Error (UE)
Does the load lean toward one
side, or is the load a few items?
NO
Is the laundry mixed?
NO
YES
YES
The few items of clothing will clump together
and their weight will be in one place on the drum,
throwing the weight off during spin mode.
So add some laundry to overcome UE error.
And rearrange load to allow proper spinning.
Try rearranging the laundry in drum
Or the laundry is separated by size, type, and color.
Separate by size,
type and color
Is the washing machine installed
at an angle?
YES
Adjust the height of washing
machine to be kept horizontally.

* How to disassemble and clean pump filter
Open the Cover by coin or
finger(only new model)
Drain water by removing the
hose cap.
Check drain hose for kink and straighten the Hose.
Drain Hose
Check & Clean Pump Filter.
This kind of accumulation on the drain filter not only
prevents proper drainage, but also will promote
bacteria growth and cause odors.
This drain filter should be cleaned once a month.
Disassemble the pump

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.
