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 efficient, 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 drying
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 off 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
film on them after a wash?
The cloudy film 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, or
run a Heavy cycle. LG Dishwashers use less water than traditional
dishwashers, so adding an Extra Rinse will aid in rinsing the film
away. If the water supply is hard, it may be necessary to add a per-
formance booster that addresses the hard water condition.
What is the Sanitary Rinse and how is it activated?
The 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?
Drying performance is directly affected by the amount of heat
that remains in the tub after the heated rinse is performed. If your
dishwasher 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 finish. 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 finish 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. This
will cause all of the dishes inside to remain wet once the cycle fin-
ishes.
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 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 effectively 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 first 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 off and let it reset. Repeat
as necessary.
