2-1. 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.
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.
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.
2-4. THE DOOR CAN NOT BE OPENED
While program is operating.
While Door Lock light is on.
2-5. NFC (Tag On Function)
The Tag On function can only be used with smart phones equipped
with the NFC function and based on the Android operating system (OS).
Position your smart phone so that the NFC antenna on the back of
your smart phone matches the position of the Tag On icon on the
appliance.
NFC reading performance of your smart phone is must be higher than
a certain level for using this function.

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 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.

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.
Press the Power button & Start / Pause button.

Before using the Tag On function
45
• The Tag On function allows you to conveniently use the LG SmartDiagnosis™ and Cycle
Download features to communicate with your appliance right from your own smart phone.
• To use the Tag On function:
1. Download the LG Smart Laundry & DW App to your smart phone.
2. Turn on the NFC (Near Field Communication) function in your smart phone.
• The Tag On function can only be used with most smart phones equipped with the NFC
function and based on the Android operating system (OS).
Turning on the NFC function of the smart phone
1. Enter the "Settings" menu of the smart phone and
select "Share & Connect" under "WIRELESS &
NETWORKS".
2. Set "NFC" and "Direct Android Beam" to ON and
select "NFC".
3. Check "Use Read and Write/P2P receive".
NOTE
• Depending on the smart phone manufacturer and
Android OS version, the NFC activation process
may differ.
• Refer to the manual of your smart phone for
details.
Before using the Tag On function
46
The Tag On guide
Tag On position
•
•
•
Because of the characteristics of NFC, if the transmission distance is too far, or if there is a
metal sticker or a thick case on the phone, transmission will not be good. In some cases,
NFC-equipped phones may be unable to transmit successfully.
Tag On:
Look for the Tag On icon next to the LCD screen on the
control panel.
This is where you position your smart phone when
using the Tag On function with the LG
SmartDiagnosis™ and Cycle Download features of the
LG Smart Laundry & DW App.
When you use the Tag On function, position your
smart phone so that the NFC antenna on the back of
your smart phone matches the position of the Tag On
icon on the appliance.
If you do not know the position of your NFC antenna,
move your smart phone very slightly in a circular
motion until the application verifies the connection.
•
Press in the LG Smart Laundry & DW app for a more detailed guide on how to use
the Tag On function.
•
NFC reading performance of your smart phone is must be higher than a certain level for
using this function.
