PRODUCT FEATURES
INVERTER DIRECT-DRIVE MOTOR
The inverter motor, which is directly connected to the drum, produces little noise and vibration and offers
great durability and a long lifespan.
SMART DIAGNOSIS™
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
(Refer to page 38).
TUB CLEAN
Regular cleaning of the tub on a monthly basis using Tub Clean can help keep the tub clean and fresh.
MAGNETIC DOOR PLUNGER
Safely and conveniently secure the door slightly ajar with the magnetic door plunger. This will promote air
circulation and allow the interior of the machine to dry. To use this feature, after the load has been removed,
do not close the door completely.
When the magnetic door plunger comes into contact with the metal washer cabinet, it will secure the door
slightly open allowing the interior of the washer to dry.
LARGE CAPACITY STAINLESS STEEL DRUM
The large capacity stainless steel drum offers extreme durability and is tilted to improve efficiency and allow
easier access for large items.
CHILD LOCK
Use this option to disable the controls during a wash cycle. This option can prevent children from changing
cycles or operating the machine.
DETERGENT DISPENSER DRAWER
The four-compartment dispenser drawer makes it easy to separate the pre-wash detergent, the main laundry
detergent, liquid bleach, and fabric softener into different compartments.
HIGH TEMPERATURE STEAM CYCLES
During LG's unique high-temperature steam cycles, the hot steam helps to remove tough stains.
TAG ON
The Tag On feature works on most NFC equipped smart phones by communicating with your Tag On
equipped LG appliance. Using the LG Smart Laundry application, the Tag On feature allows you to diagnose
your appliance, download new cycles, and see the status of your appliance by simply touching the smart
phone to the Tag On logo of the appliance.

This symbol alerts you to potential hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol and either the word DANGER, WARNING or CAUTION.
These words mean:
DANGER

You can be killed or seriously injured if you don’t follow instructions.

BASIC SAFETY PRECAUTIONS
WARNING
To reduce the risk of fire, electric shock, or injury to persons when using this appliance, follow basic precau-
tions, including the following.
• Use this appliance only for its intended purpose as
described in this owner’s Manual.
• Before use, the washer must be properly installed as
described in this manual.
•Do not wash articles that have been previously
cleaned in, washed in, soaked in, or spotted with
gasoline, dry cleaning solvents, or other flammable or
explosive substances, as they give off vapors that
could ignite or explode.
• Do not add gasoline, dry cleaning solvents, or other
flammable or explosive substances to the wash water.
These substances give off vapors that could ignite
or explode.
• Under certain conditions, hydrogen gas may be
produced in a hot water system that has not been
used for 2 weeks or more. HYDROGEN GAS IS
EXPLOSIVE. If the hot water system has not been
used for such a period, before using the washer, turn
on all hot water faucets and let the water flow from
each for several minutes. This will release any accu-
mulated hydrogen gas. As the gas is flammable, do
not smoke or use an open flame during this time.
•Do not allow children to play on or in the washer.
Close supervision of children is necessary when the
washer is used near children.
•Before the washer is removed from service or dis-
carded, remove the lid to prevent children from climb-
ing inside.
•Do not install or store the washer where it will be
exposed to the weather or freezing temperatures.
•Do not tamper with controls.
•Keep the area underneath and around your appli-
ances free of combustible materials (lint, paper,
rags, etc.), gasoline, chemicals and other flammable
vapors and liquids.
• Do not repair or replace any part of the washer or
attempt any servicing other than as described in this
manual. We strongly recommend that any service
be performed by a qualified technician.
• See Installation Instructions for grounding require-
ments.
• ALWAYS follow the fabric care instructions supplied
by the garment manufacturer.
• Do not place items exposed to cooking oil in your
washer. Items contaminated with cooking oils may
contribute to a chemical reaction that could cause a
load to catch fire.
• Use fabric softeners or products to eliminate static
only as recommended by the manufacturer.
• This washer is not designed for maritime use or for
mobile installations such as in RVs, aircraft, etc.
• Turn off the water faucets and unplug the washer if
the machine is to be left for an extended period of
time, such as during vacations.
• Do not use to dry articles containing foam rubber or
similarly textured rubber-like materials.
• Packaging material can be dangerous for children.
There is a risk of suffocation! Keep all packaging
from children.
• Always check the inside of the washer for foreign
objects before loading laundry. Keep the lid closed
when not in use.
• Do not reach into the appliance if the tub or agitator is
moving.
• WARNING : This product contains chemicals known
to the State of California to cause cancer and birth
defects or other reproductive harm. Wash hands
after handling.

WARNING
For your safety, the information in this manual must be followed to minimize the risk of fire or explosion,
electric shock, or to prevent property damage, injury to persons, or death.
GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of malfunction or breakdown, grounding will reduce the risk
of electric shock by providing a path of least resistance for electric current. This appliance is equipped with
a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
WARNING
Improper connection of the equipment-grounding conductor can result in risk of electric shock. Check with a
qualified electrician or servicer if you are in doubt as to whether the appliance is properly grounded. Do not
modify the plug provided with the appliance. If it does not fit the outlet, have a proper outlet installed by a
qualified electrician. Failure to follow these warnings can cause serious injury, fire, electric shock, or death.
