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.

All safety messages will follow the safety alert symbol and either the word DANGER, WARNING or CAUTION.

These words mean:

DANGER

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

WARNING

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

CAUTION

You may be slightly injured or cause damage to the product if you do not follow instructions.

All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury,

and tell you what can happen if the instructions are not followed.

BASIC SAFETY PRECAUTIONS

WARNING

To reduce the risk of fire, electric shock, or injury to persons when using this appliance, follow basic precautions, 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 discarded, remove the lid to prevent children from climbing 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 requirements.

• 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.

IMPORTANT SAFETY INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE USE

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.

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.

SAFETY INSTRUCTIONS FOR INSTALLATION

WARNING

To reduce the risk of fire, electric shock, or injury to persons when using this appliance, follow basic precautions, including the following.

• Refer to INSTALLATION INSTRUCTIONS for detailed grounding procedures. Installation instructions are

packed with the washer for installer’s reference. If the washer is moved to a new location, have it checked and reinstalled by a qualified service technician. Failure to follow this warning can cause serious injury, fire, electric shock, or death.

• Do not, under any circumstances, cut or remove the third (ground) prong from the power cord. Failure to

follow this warning can cause serious injury, fire, electric shock, or death.

• For personal safety, this appliance must be properly grounded. Failure to follow this warning can cause

serious injury, fire, electric shock, or death.

• The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates with a standard 3-prong (grounding) wall outlet to minimize the pos-

sibility of electric shock from this appliance.

• This washer must be plugged into a 120 VAC, 60 Hz grounded outlet. Failure to follow this warning can

cause serious injury, fire, electric shock, or death.

• Have the wall outlet and circuit checked by a qualified electrician to make sure the outlet is properly grounded. Failure to follow this warning can cause serious

injury, fire, electric shock, or death.

• Where a standard 2-prong wall outlet is encountered, it is your personal responsibility and obligation to have it replaced with a properly grounded 3-prong wall outlet. Failure to follow this warning can cause

serious injury, fire, electric shock, or death.

• Do not install on carpet. Install washer on a solid floor. Failure to follow this warning can cause serious leak damage.

• Do not remove ground prong. Do not use an adapter or extension cord. Plug into a grounded 3-prong outlet. Failure to follow these warnings can cause

serious injury, fire, electric shock, or death.

• The washer should always be plugged into its own individual electrical outlet which has a voltage rating that matches the rating plate. This provides the best

performance and also prevents overloading house wiring circuits which could cause a fire hazard from overheated wires.

• Never unplug your washer by pulling on the power cord. Always grip plug firmly and pull straight out

from the outlet. Failure to follow this warning can cause serious injury, fire, electric shock, or death.

follow this warning can cause serious injury, fire, electric shock, or death.

• The washer must be installed and electrically grounded by a qualified service person in accordance with local codes to prevent shock hazard and assure

stability during operation.

• The washer is heavy. Two or more people may be needed to install and move the appliance. Failure to

do so can result in back or other injury.

• Store and install the washer where it will not be exposed to temperatures below freezing or exposed to outdoor weather conditions. Failure to follow this

warning can cause serious leak damage.

• Do not install the washer in humid spaces to reduce the risk of electric shock. Failure to follow this warn-

ing can cause serious injury, fire, electric shock, or death.

• To reduce the risk of injury to persons, adhere to all industry recommended safety procedures including the use of long sleeved gloves and safety glasses.

• Disconnect this appliance from the power supply before attempting any user maintenance. Turning the controls to the OFF position does not disconnect this appliance from the power supply. Failure to follow

this warning can cause serious injury, fire, electric shock, or death.

• Do not combine laundry products for use in one load unless specified on the label.

• Do not mix chlorine bleach with ammonia or acids such as vinegar. Follow package directions when using laundry products. Incorrect usage can produce

poisonous gas, resulting in serious injury or death.

• Do not reach into the washer while parts are moving. Before loading, unloading, or adding items, press the START/PAUSE button and allow the drum to coast to a complete stop before reaching inside. Failure to fol-

low this warning can cause serious injury, fire, electric shock, or death.

• Do not allow children to play on or in the washer. Close supervision of children is necessary when the washer is used near children. As children grow, teach them the proper, safe use of all appliances. Failure to

comply with these warnings could result in serious injury to persons or death.

• Destroy the carton, plastic bag, and other packing materials after the washer is unpacked. Children might use them for play. Cartons covered with rugs, bedspreads, or plastic sheets can become airtight chambers. Failure to comply with these warnings

could result in serious injury to persons or death.

• Keep laundry products out of children’s reach. To prevent injury to persons, observe all warnings on product labels. Failure to comply with these warn-

ings could result in serious injury to persons or death..

• Remove the door to the washing compartment to avoid the danger of children or small animals getting trapped inside before your washer is removed from service or discarded. Failure to do so can result in

serious injury to persons or death.

• Make sure the dispenser drawer is closed at all times when not being filled with laundry products. Failure to

keep the drawer closed can result in personal injury or flooding.

INSTALLATION

Choosing the Proper Location

Install the washing machine on a solid floor that is strong and rigid enough to support the weight of the washing machine, even when fully loaded, without flexing or bouncing. If the floor has too much flex, you may need to reinforce it to make it more rigid. If the floor is not solid, it may cause severe vibration and noise.

Clean the floor before installation.

- Make sure to select solid and smooth ground.

Two or more people are needed for moving and

unpacking the washing machine.

Allow for sufficient space between the walls and

the washing machine for installation.

Space Requirements

You must allow sufficient space for water lines, the drain line, and airflow.

NOTE

yBe sure to allow for wall, door, or floor moldings

that may increase the required clearances.

Clearances

22 ¼"

(56.6 cm)

NOTE

yThe floor must be strong and rigid enough to

support the weight of the washer, when fully loaded, without flexing or bouncing. If your floor has too much flex, you may need to reinforce it to make it more rigid. A floor that is adequate for a top-loading washer may not be rigid enough for a front loading washer, due to the difference in the spin speed and direction. If the floor is not solid, your washer may vibrate and you may hear and feel the vibration throughout your house.

yBefore installing the washer, make sure the

floor is clean, dry and free of dust, dirt, water and oils so the washer feet can not slide easily. Leveling feet that can move or slide on the floor can contribute to excess vibration and noise due to poor contact with the floor.

yIf a drip pan must be used, take extra care

to follow the instructions provided with the drip pan and make sure the leveling feet are adjusted for firm and even contact with the pan. Use of drip pans and failure to properly level the machine may result in increased vibration and noise during operation.
