2. FEATURES & TECHNICAL EXPLANATION
2-1. FEATURES
Direct Drive System
The advanced Brushless DC motor directly drives the drum without belt and pulley.
Tag on
This is a function that may use Diagnosis, Download Course, Washing Coach, One
Touch Washing, etc. when you touch the Tag On logo of the washing machine by using
your smartphone with NFC.
Child Lock
The Child lock prevents children from pressing any Buttons to change the settings during
operation.
More economical by Intelligent Wash System
Intelligent Wash 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.
Low noise speed control system
By sensing the amount of load and balance, it evenly distributes load to minimize the
spinning noise level.
Auto Restart
Auto Restart allows the program to restart all by itself in case of power
Failure. It does from the stage where it stopped.
SmartDiagnosis™
Should you experience any technical difficulty with your washing machine, it has the
capability of transmitting data by phone to the Customer Information Center. The call
center agent records the data transmitted from your machine and uses it to analyze the
issue, providing a fast and effective diagnosis.
Inverter Direct Drive system
The advance Brushless DC motor directly drives the drum without belt
and pulley.
6 motion
Washer is able to perform various drum actions or a combination of different actions
depending on the wash program selected.
Combined with a controlled spin speed and the ability of the drum to rotate both
left and right, the wash performance of the machine is greatly improved, givong
you perfect results every time.

2-2. DETERMINE WASHING TIME BY FUZZY LOGIC
To get the best washing performance optimal time is determined by sensing the water
temperature, selected washing temperature and laundry amount.
2-3. WATER LEVEL CONTROL
This model adopts a pressure sensor which can sense the water level in the tub.
Water supply is stopped when the water level reach the preset level, then washing program proceeds.
Spinning does not proceed until the water in the tub reduces to a certain level.

4. INSTALLATION
INSTALLATION
The appliance should be installed as follows.
Check the conditions of installation area.
1. Check level ground.
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 for humidity or any foreign objects under the feet.
Clean the floor, there should be no 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.
1
Open the box and check appliance condition.

Step 1
If washing machine legs are loose or not Screwed in, then tighten with the spanner wrench.
Using the level, level the washing machine from front to back and side to side.
Step 2
Use the spanner wrench to adjust Legs until level and try the Diagonal test.
Step 3
Perform a Rinse and Spin with some clothing in the machine.
To do this, put 2~3kg of clothing in the unit, turn on the unit, Select the Rinse+Spin
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. (Repeat step 2)
Step 4
Tighten the lock nut against the base of the machine to lock the position leg.
Lower the foot until there is no gap between floor and foot.
And only use adjustment rubber when difference at the leg adjustment is more than 10mm.
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.
