COMMON PRODUCT QUESTIONS

Is a rinse aid required to be used?

Rinse aid is strongly recommended to enhance the drying perfor-

mance of the dishwasher. In order to be more energy ecient, the

hybrid drying system does not utilize a heating element in order

to assist in drying, so a rinse aid plays an integral role in the dry

process. If a rinse aid is not used, water may remain on the dishes

and the tub. Rinse aid will help to ensure that the majority of the

water has been sheeted o of the dishes at the end of the rinse

and that the load is ready for the dry cycle.

What can be done if my dishes have a cloudy, white

lm on them after a wash?

The cloudy lm is usually caused by minerals in the water react-

ing with the dishwasher detergent. First, be certain not to use too

much detergent. Refer to the owner’s manual for recommended

detergent amounts by cycle. Add an Extra Rinse to the cycle. Add

an Extra Rinse, or run a Heavy cycle. LG Dishwashers use less water

than traditional dishwashers, so adding an Extra Rinse will aid in

rinsing the lm away. If the water supply is hard, it may be neces-

sary to add a performance booster that addresses the hard water

condition.

What is the Sanitary Rinse and how is it activated?

Sanitary Rinse will increase the heated rinse to approximately

161°F (72°C). The normal heated rinse temperature will vary from

cycle to cycle.

What steps can I take to improve drying results?

Dry performance is directly aected by the amount of heat that

remains in the tub after the heated rinse is performed. If your dish-

washer is far away from your home’s hot water heater, it may be

necessary to run the hot water tap in the sink before starting a

wash cycle, to ensure that cool water is purged from the hot water

lines. This will ensure your dishwasher has a consistent supply of

hot water from start to nish. Using the Sanitary Rinse setting will

also aid in keeping the inner drum temperature and dishes hotter

before drying begins.

LG dishwashers are designed to be used in conjunction with a

rinse aid. Using a rinse aid will maximize the amount of water that

has already been sheeted away from the dishes before the dry

cycle begins. If a rinse aid is used and the performance still needs a

boost, adjust the amount of rinse aid used by the indicator on the

rinse aid cap. 4 is the default setting, but if necessary, set the level

to 5 so more rinse aid will be used.

Allow the dishwasher to completely nish the dry cycle before

opening the door. If the door is opened mid dry cycle, the heat

that is necessary for the hybrid dry system to work will escape out.

This will cause all of the dishes inside to remain wet once the cycle

nishes.

What is the hybrid drying system?

The dishwasher does not rely on a heating element for the drying

process; instead, it relies on the heat that is retained by the dishes

and the tub during the wash and rinse cycles to turn the moisture

in the tub into humidity. Warm, moist air in the dishwasher is then

pulled into a condensing duct in the door by a fan. The air then

cools, which causes the humidity to condense. Room tempera-

ture air is also drawn into the duct to help the air cool down faster.

When this moisture condenses into a liquid, it is drained out.

Rinse aid is required to enhance the drying perfor-

mance. If no rinse aid is used, water may remain on

the dishes and the tub.

NOTE

Why is there a whistling sound?

It is important to determine how long the noise occurs and when

it happens (what part of the cycle). When water is drawn into the

dishwasher, a whistling noise can be heard. This is normal. If the

water pressure is too high, it will be louder so it may be necessary

to adjust the water valve to lower the pressure if the noise is too

loud.

What is Dual Control?

Dual Control is an option that can be utilized during wash cycles.

This option enables you to fully customize the wash cycle inten-

sity for the upper and lower racks, independently, in the same

load. For example, by selecting a soft spray for the upper rack and

strong spray for the lower rack, you can wash delicate stemware

in the upper rack while washing pots and pans in the lower rack.

What kind of dishes can be placed in the

dishwasher?

Ensure that the dishes you place in the dishwasher are dishwasher

safe. Plastic dishware will not dry as eectively as glass and met-

al dishware. Plastic items do not retain heat as well as glass and

metal dishware. Plastic cups and dishes may require some hand

drying before being put away at the end of the cycle.

Can I perform a drain only cycle?

The dishwasher does not have a drain only function; however, the

dishwasher will drain on its own for the rst 45 seconds of a new

cycle. To drain standing water, select a wash cycle and let it run

for only 45 seconds. Then, turn the unit o and let it reset. Repeat

as necessary.
