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 Tub Clean (Downloaded: 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 option for better drying results. The Dry Boost Low option is automatically added to the Normal cycle and the Dry Boost High option is automatically added to the Auto and Heavy cycles for better drying performance.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.Q: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.After the dishwasher door is opened at the end of the cycle, warm and moist air in the dishwasher is then blown out by heat dry blower.Rinse aid is required to enhance the drying performance. If no rinse aid is used, water may remain on the dishes and the tub.Q:Why am I hearing a whistling sound from the dishwasher?A:It is important to determine the duration of the noise 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.Q:What kinds of dishes can be placed in the dishwasher?A:Ensure that the dishes you place in the dishwasher are dishwasher safe. Plastic dishware will not dry as effectively as glass and metal 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.Q:Can I run a drain only cycle?A:To drain standing water, press and hold START for three seconds until the cycle stops. Once the dishwasher finishes draining, the power turns off.Q:Why does my dishwasher continuously chime if I open the door during a cycle or right after the cycle has finished?A:This is normal. The dishwasher is letting you know that the interior temperatures of the unit are hot and to use caution when reaching inside. Once the unit has cooled down, the chiming will stop.Q:Can I add an extension to the drain hose?A:If a drain hose extension is required, use a 5/8" or 7/8" inside diameter, 2 ft ~ 3 ft. length hose and a coupler to connect the two hose ends.Q:An LED is blinking, the machine is chiming, and the dishwasher won't start. What is wrong with the dishwasher?A:This is a safety feature. The door must be closed within four seconds of pressing the START button. If the door is not closed within four seconds, an LED flashes, and the dishwasher does not operate. To start the dishwasher, open the door and either close the door and press START (front controls) or press START and close the door within four seconds (top controls).Q:Should I pre-rinse dishes before loading them?A:No, you don't need to pre-rinse the dishes before loading especially if using the Normal and Auto cycles. The dishwasher washes dishes clean without pre-rinsing.
