FAQs: Frequently Asked Questions

Q: Does this dishwasher require a rinse aid to be used?

A: Rinse aid is strongly recommended to enhance the drying performance of the dishwasher. In order to

be more energy efcient, the hybrid drying system does not use a heating element 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 helps 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.

Q: What can be done if my dishes have a cloudy, white lm on them after a wash?

A: The cloudy lm is usually caused by minerals in the water reacting with the dishwasher detergent.

First, be certain not to use too much detergent. Refer to Adding Detergent to the Dispenser section

for recommended detergent amounts. Add an extra rinse to the cycle. LG Dishwashers use less

water than traditional dishwashers, so adding an extra rinse aids in rinsing the lm away. If the water

supply is hard, it may be necessary to add a performance booster that addresses the hard water

condition.

Q: How do I remove white lm on the tub?

A: Measure 3 tbsp. (40 g) of citric acid powder and use it to ll the main detergent compartment. Run a

Machine Clean cycle. Do not use detergent.

Q: What steps can I take to improve drying results?

A: 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 nish. Using the High Temp setting also aids 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. 2 is the default setting, but if necessary set the level to 3 so more rinse aid is used.

Water tends to bead rather than sheet off plastic and nonstick surfaces, making them more difcult

to dry. If washing plastic items in a Normal cycle, select the Extra Dry or Night Dry option or both for

better drying results. When the rinse aid is empty, the Extra Dry option is selected automatically.

Allow the dishwasher to completely nish the dry cycle before opening the door. If the door is opened

in the middle of the 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 nishes.

TROUBLESHOOTING 45 What is the hybrid drying system? A: 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.

46 TROUBLESHOOTING Q: What is Control Lock and how is it activated? A: Control Lock is a feature that prevents the controls from being changed during the cycle. It does not prevent the door from being opened or the unit from being powered off. To activate or deactivate, press and hold Half Load and Energy Saver simultaneously for three seconds. Q: Can I add an extension to the drain hose? A: If an extension drain hose is required, use 5/8" or 7/8" inside diameter, 2-3 ft.
