Final Check
The appearance and specifications listed in this manual may vary due to constant product improvements.
This dishwasher is designed to fit a standard dishwasher opening. An opening may be needed on both sides to route plumbing and electrical connections.
1 Select a location as close to the sink as possible for easy connections to water supply line, drain hose and electrical connection.
2 To allow for proper clearance of plumbing and electrical, use the template included with the literature to determine the clearance on the side of the cabinet where the cabinet meets the back wall. Using a 2 ½” diameter hole saw, drill a hole in the target area as shown on the template.
There are 2 channels in the bottom of the dishwasher for routing the water and electrical connections. As shown in the bottom view below, channel 1 is for the water supply line, and channel 2 is for the electrical cable.
Remove the twist tie holding the drain hose to the back of the shipping brace.
The rear shipping brace can be removed if additional clearance is needed when installing the dishwasher under a low countertop.
1. Remove the screws at either side which attach the lower cover to the dishwasher.
2. Remove the lower cover.

To maintain performance and prevent trouble, it is important to check the outside and inside of the dishwasher, including filters and spray arms, at regular intervals.
Check the drain air gap or in-sink disposal if the dishwasher is not draining well.
Cleaning the Air Gap
1 Turn off the dishwasher.
2 Remove the air gap cover and the plastic cap underneath it.
3 Clean out any debris with a toothpick or brush.
4 Replace the plastic cap and air gap cover.
1 Remove the lower rack and position the bottom spray arm so a wider vee is open to the front.
2 Turn the inner filter counter-clockwise and take out the assembled inner filter and stainless steel filter.
With the filters removed, check the sump opening and remove any foreign materials, if needed.
3 Clean the filters with a soft brush under running water. Reassemble the filters before reinstalling them.
4 To replace the assembled filters, position the spray arm so the wider vee is toward the front. Fit the filters back into the filter holder and secure them by turning the inner filter clockwise until it clicks into place.
Recommended Filter Cleaning Schedule
If the spray arm holes are blocked by any food residue, dishes may not be cleaned well due to improper water spray.
It is recommended that the spray arms be cleaned once every two weeks.
Cleaning the Lower Spray Arm
1 Make sure that the water jet holes are not blocked by food particles.
2 If any food residue blocks the spray arm holes, remove it with a pin or any sharp tool.
1 Pull the upper rack forward. Make sure that the water jet holes are not blocked by food particles.
2 When cleaning is necessary, remove the upper spray arm by turning the nut on the bottom of the spray arm 1 turn counter-clockwise and pulling down.
3 Remove food particles by rinsing or shaking the spray arm.
4 If any food residue blocks the spray arm holes, remove it with a pin or any sharp tool.
5 After removing the food residue, clean the spray arms holes under running water.
6 After cleaning the upper spray arm, press it up into place. Turn the nut 1 turn clockwise to make sure that the nut locks back into place.
7 After assembly, check whether the spray arms rotate freely.
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.
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.
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 temperature 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.
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 perform 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 placing your hands inside. Once the unit has cooled down, the chiming will stop.
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 or 7 inside diameter, 2-3 ft. length hose and a coupler for connecting 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, an audible alert sounds, 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: Before loading dishes, should I pre-rinse dishes?
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.
