The washer is equipped with an automatic error-monitoring system to detect and diagnose problems at an
early stage. If the washer does not function properly or does not function at all, check the following before
you call for service.
Before Calling for Service
FAQs
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. 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 helps to rinse 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 (Download Cycle: P1) 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 Dry Boost or Night Dry option or both
for better drying results. When the rinse aid is empty, the Dry Boost option is selected automatically
(except the Normal, 1 Hour cycle).
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.
