Product Features

Inverter Direct Drive system

The advanced 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, giving you perfect results every time.

Turbo Wash

Wash the laundries in 1 hour with energy and water saving.

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.

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.

Child Lock

The Child Lock prevents children from pressing any button to change the settings during operation.

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.

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.

INSTALLATION

The appliance should be installed as follows.

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 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.

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.

Check the horizontality with a level (Gage).

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.

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.
