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 efficient, 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 film on them after a wash?
A: The cloudy film 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 film 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 film on the tub?
A: Measure 3 tbsp. (40 g) of citric acid powder and use it to fill 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 finish. 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 difficult 
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 finish 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 finishes.
