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 ecient, 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 Steam Power or Power Scrub cycle. LG 
Dishwashers use less water than traditional dishwashers, so add-
ing an Extra Rinse will aid in rinsing the lm away. If the water sup-
ply is hard, it may be necessary to add a performance booster that 
addresses the hard water condition.
What is the Sanitary option and how is it activated?
When selected, the Sanitary option increases the temperature 
of the heated rinse to approximately 161 °F (72 °C). The normal 
heated rinse temperature varies from cycle to cycle. Depending 
on the model, activate the Sanitary option as follows: either press 
the Sanitary button, press the Option button repeatedly, or press 
the Rinse button repeatedly until the Sanitary light shows in the 
display.
What steps can I take to improve drying results?
Dry performance is directly aected 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 Steam Dual?
Steam Dual 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 eectively 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.
