2. FEATURES & TECHNICAL EXPLANATION
2-1. Product Features
Inverter Direct Drive system
The advanced Brushless DC motor directly drives the drum without
belt and pulley.
Low noise speed control system
By sensing the amount of load and balance, it evenly distributes load
to minimize the spinning noise level.
Child Lock
The Child Lock prevents children from pressing any button to change
the settings during operation.
More economical with Intelligent Wash system
Intelligent Wash System detects the size of load and water temperature,
and then determines the optimum water level and washing time to
minimize energy and water consumption.
Smart ThinQ (Wi-Fi feature)
This feature lets you use various functions of the product, e.g., remote
control, smart alert, mode download, and smart self-diagnosis via the
smartphone app.
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, giving you perfect results every time.
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.

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.

Open the box and check appliance condition.

Connect Drain Hose.

Connect power plug.

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