Preparing Cabinet Opening

This dishwasher is designed to fit a standard dishwasher opening. An opening may be needed on both sides to route plumbing and electrical connections.

• To ensure proper drainage, install the dishwasher no more than 12 ft. (3.65 m) from the sink.
• The location must have sufficient space for the dishwasher door to open easily and provide at least 0.1” (2 mm) between the dishwasher and the cabinet sides.
• If installing the dishwasher in a corner, leave a minimum of 2” (50 mm) between the dishwasher and the adjacent wall.
• The adjacent wall must be free of obstructions.
• For flush installations only, you may remove the cabinet brace 1 inside the cabinet.

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 1 /2” diameter hole saw, drill a hole in the target area as shown on the template.

Preparing Water and Electrical Connections

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.

1. Turn off the house water supply and the circuit breaker or dedicated power before connecting the dishwasher.
2. Run the water supply line along the floor 6 1 /2 – 7 3 /4” (165–197 mm) from the left side of the opening and tape it in place in front of the opening.
3. Run the electrical cable 3 along the floor 14–16” (356–406 mm) from the water supply line 4 and tape it in place.

• The electrical outlet must be within 4 ft. (1.22 m) of either side of the dishwasher.
• The best location for the electrical conduit is on the right side of the back wall. Re-route the electrical cable before installation if the electrical conduit pipe is longer than 3” (76 mm) and is centered on the back wall.

• To avoid chipping, do not let stemware touch other items.
• Place items so that the open end faces down for cleaning and drying.
• Do not stack items on top of each other.
• Use the upper rack for small or delicate items such as small plates, cups, saucers, glasses, and dishwasher-safe plastic items.
• Cups, glasses, and bowls must be positioned upside down.
• Make sure items do not interfere with the rotation of the spray arms above and below the upper rack.
• When loading larger items in the upper rack, such as wine glasses or taller cups, it may be necessary to remove the cutlery rack if one is present.

Adding Cleaning Agents

Adding Detergent to the Dispenser

• Remove the label on the dispenser prior to running the dishwasher for the first time.
• The amount of detergent needed depends on the cycle, load size, and soil level of dishes.
• Put detergent into the detergent compartment before starting any cycle, except the Rinse cycle.

1. Push the button on the dispenser lid to open the cover.
2. Add dishwashing detergent to the main wash compartment until the level is between the lines marked 15 and 25. Fill to over the 25 line for hard water or heavily soiled loads. Fill to the 15 line for soft water or lightly soiled loads.
3. Push the detergent lid to slide the lid closed until it clicks.
4. If a prewash is desired, fill the recessed prewash compartment area on the lid with detergent.

Adding Rinse Aid to the Dispenser

The Rinse Aid indicator appears in the display when more rinse aid is needed. The use of rinse aid is recommended to prevent water spots on dishes and to enhance drying performance.

1. Open the rinse aid lid by lifting up the flap.
2. Add a liquid rinse aid to the maximum fill level. The rinse aid should be settled in the dispenser while filling, or air bubbles may result in poor drying performance. Avoid overfilling the dispenser.
3. Close the lid to lock the dispenser. Rinse aid is dispensed automatically during the final rinse cycle.

Rinse Aid Dispenser Adjustment

The dispenser has five adjustment levels. The dishwasher is programmed at the factory for a rinse aid dispenser level of 2. This can be checked and altered by using the buttons on the control panel.

1. Ensure the appliance is off.
2. Press Dual Zone and Power simultaneously to check the current setting.
3. Press Delay Start to change the rinse aid dispenser setting. Each press of the button changes the setting one step from L0 to L4.
4. Once the desired rinse aid dispenser setting is selected, press Start to save.

NOTE

• Adjust the setting higher if you have hard water and notice calcium buildup on your dishes.
• Setting the rinse aid control too low will contribute to spotting and streaking on dishes and poor drying performance.
• Setting the control too high can cause foaming, which will cause poor wash performance.

MAINTENANCE

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.

NOTE

• If you have not used the dishwasher for a long time, refresh the inside by running the Machine Clean cycle without detergent. When the cycle is finished, clean the inside and outside of the dishwasher according to the Maintenance instructions.

Cleaning the Exterior

• In most cases, the exterior of the dishwasher can be cleaned with a soft damp cloth or sponge, then dried with a soft cloth. If the dishwasher has a stainless steel exterior, use a stainless steel cleaner.

Cleaning the Interior

• Clean the interior of the dishwasher periodically with a soft, damp cloth or sponge to remove food and dirt particles.
• To remove white spots and odor from inside the dishwasher, run an empty cycle, without detergent, with one cup of white vinegar in a dishwasher safe glass or bowl placed on the upper rack. (Vinegar is an acid and with constant use it could damage the appliance.)

Seasonal Maintenance and Storage

• If you will be absent for an extended period of time during warmer months, close the water valve and disconnect the power supply line, or turn off the circuit breaker. Clean the filter, tub and dispenser to prevent odor.

• If you will be absent for an extended period of time during colder months and there is a possibility of freezing temperatures, winterize the water supply lines and the dishwasher itself. Winterization must be performed by qualified service personnel.

TROUBLESHOOTING

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.

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 /8" or 7 /8" 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.
