IMPORTANT SAFETY INSTRUCTIONS

IMPORTANT SAFETY INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE USE

Your safety and the safety of others is very important.

We have provided many important safety messages in this manual and on your appliance. Always read and follow all safety messages.

This is the safety alert symbol. This symbol alerts you to potential hazards that can result in property damage or serious bodily
harm, even death.

The safety alert symbol will be followed by either the word “WARNING” or “CAUTION” then an important safety message. These
words mean:

WARNING

Indicates the possibility of serious bodily harm or death.

CAUTION

Indicates the possibility of injury or damage to property.

BASIC SAFETY PRECAUTIONS

WARNING

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

y Read all instructions carefully before using the dishwasher.

y Use the dishwasher only for its intended function.

y Only use detergents or rinse agents recommended for use in a

dishwasher. Keep all dishwasher detergents and additives out
of the reach of children.

y This appliance is not intended for use by young children.

y When loading items to be washed:

1) Load sharp items so that they are not likely to damage the
door seal.

2) Load sharp knives with the handles up to reduce the risk of
injury when reaching into the dishwasher.

y Do not wash plastic items in the dishwasher unless they are

labeled “dishwasher safe” or the equivalent. For plastic items
that are not so labeled, check the manufacturer’s recommen­dations.

y Do not operate the dishwasher unless all enclosure panels are

properly in place.

y Do not tamper with the controls.

y Do not abuse, sit on, or stand on the door or dish racks of the

dishwasher.

y To reduce the risk of injury, do not allow children to play in or

around the dishwasher.

y Under certain conditions, hydrogen gas may be produced in

a hot water system that has not been used for two weeks or
more. HYDROGEN GAS IS EXPLOSIVE. If the hot water system
has not been used for such a period of time, turn on all hot
water faucets and let the water ow for several minutes. This
will release any accumulated hydrogen gas. Since hydrogen
gas is ammable, do not smoke or use an open ame during
this time.

y Remove the door to the wash compartment when disposing of

an old dishwasher.

This manual contains very important information regarding the installation, use, and maintenance of your dishwasher. The manufacturer
cannot be responsible for injuries or damage caused by failure to follow these safety and caution instructions.

y The dishwasher is designed to be used with standard household current (120 Volts AC, 60Hz.). Before connecting the dishwasher, ensure

that the outlet or cable is properly grounded and polarized by circuit breakers or fuses. Failure to provide adequate grounding of this
appliance may cause electrical shock or malfunction of the appliance. Consult with a qualied electrician.

IMPORTANT SAFETY INFORMATION

BEFORE USING THE DISHWASHER

Before using the dishwasher, please read the Important Safety
Instructions.

Water supply temperature should be a minimum of 120°F (49°C)
for better washing and reasonable cycle time.

For this reason, use the hot water supply only. It is also important
that the dishwasher is loaded according to instructions for eec­tive cleaning. When loading the dishwasher, make sure that in­soluble items such as bones, toothpicks, and pieces of paper have
been removed.

SAVE THESE INSTRUCTIONS

When loading the dishwasher, observe the following general
guidelines:

1. Place items with deep dish bottoms at an angle to help water
run o and speed the drying process.

2. Remove solid, burned-on scraps from dishes prior to loading
in the dishwasher.

3. Only load items that are dishwasher-safe.

Do not load utensils that are not heat-resistant, have
decorative metal trim, etc.

PARTS AND FEATURES

PARTS AND FEATURES

FE ATU RE S

LARGE CAPACITY

LG dishwashers allow you
to load very large items in
both the upper and lower
racks. The tall tub pro­vides extra overall capaci­ty and the clearance to ac­commodate large dishes.
Extra large items (max. 14
in.) may be loaded in the
lower rack by raising the
upper rack.

SLIM DIRECT MOTOR™

The new Slim Direct Mo­tor™ is inverter-controlled.
Wash power is controlled
based on cycle selection.
It also oers high energy
eciency to minimize en­ergy use.

HYBRID DRYING SYSTEM

This system eectively
dries dishes without the
use of a heating element
that would increase en­ergy consumption.

STEAM WASHING

Steam technology pro­vides better cleaning
performance than regu­lar wash systems. Steam
is the most energy e­cient gentle care for your
nest china and stem­ware.

VARIABLE SPRAY SYSTEM

Because the water spray
alternates between the
upper and lower racks,
all of the power from the
motor is directed to one
rack at a time. This con­centrates all the clean­ing power of the motor
on each rack in turn.

LIGHT TOUCH BUTTONS AND BLUE LCD

The light touch buttons
on the control panel
make selections easy
and convenient. The
blue LCD display clearly
displays the selected
cycle and options.

to soften dried on residue. Rinsing the dishes will help pre­vent odors in the dishwasher. No detergent should be used.
To select the Rinse Only cycle, turn the dishwasher on, and
press the Rinse button once without pressing any other cycle
buttons.

the display will show the total estimated time to complete

those selections. During operation, the display shows the re­maining estimated operating time.

• The estimated time shown in the display does not in­clude delay times for heating water, etc.

• If Delay Wash is selected, the display shows the delay
time in hours.

• Time may vary depending on the soil level of your load.

save energy. Each press of the Half Load button cycles be­tween upper rack only and lower rack only.

DELAY S TA RT

The Delay Start feature allows you to delay the start of a se­lected cycle. Each time the Delay Start button is pressed, the
delay time will increase an hour. The delay start time can be
set from 1 to 24 hours, in one-hour increments.

EXTRA DRY

Select the EXTRA DRY option for better drying performance.
This option adds 30 minutes of extra drying time to the cycle.
The EXTRA DRY button will illuminate when the option has
been selected.

ECO

The ECO option saves energy by using less water. This option
should only be used with light to medium soiled dishes.

4. POWER

y Press the Power button to turn on the control panel. If no

cycle is selected within four minutes, the dishwasher will
power o.

y After the cycle is complete, the power automatically turns

o for safety and economy purposes.

any kind, the PF indicator will display and power will be au­tomatically turned o for safety. The cycle will need to be
restarted.
