Product Specifications

The appearance and specifications listed in this manual may vary due to constant product improvements.

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 (4) line 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.
     

Preparing Dishwasher

WARNING : Do not remove safety cover (1) . Removal can result in fire, electric shock or death.

Releasing Drain Hose

Remove the twist tie holding the drain hose to the back of the shipping brace.

Removable Shipping Brace

The rear shipping brace can be removed if additional clearance is needed when installing the dishwasher under a low countertop

Removing Lower Cover

1. Remove the screws at either side which attach the lower cover to the dishwasher.
   
2. Remove the lower cover.
3. If there is insulation padding behind the lower cover, remove it.
4. Set the parts aside until the installation is complete.

Removing Packing Materials from the Interior

Remove all packing materials from the interior of the dishwasher before installing the appliance.

Attaching Installation Brackets

For countertops made of wood or other material that will not be damaged by drilling, use the metal installation brackets provided. For countertops made of granite, marble, or other materials that could be damaged by drilling, use the wood screws to attach the dishwasher to the cabinet.

• 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.

Folding Down the Upper Tines

Fold tines down to fit larger dishes; pull tines back up to fit smaller dishes.

Loading Dishes & Pots

Height Adjustable Upper Rack

The upper rack adjusts up and down. Raise the upper rack to allow items up to 14” tall in the lower rack. Lower the upper rack to allow dishes up to 12” tall in the upper rack. The dishwasher ships with the upper rack raised. There are three available positions for adjusting the height of the upper rack to create more space.

Lowering the Rack:

Hold the rack at the center of each side to support its weight. Then, push the button on each side to release the rack and lower it to the lower position.

Raising the Rack:

Lift the rack at the center of each side until the rack locks into place in the upper position. It is not necessary to lift the lock levers to raise the rack.

NOTE

• Raise the upper rack without pushing the buttons on each side. Pushing the buttons when raising the rack will prevent the rack from locking into position.
• To set the rack to the middle position, it may be easier to lower the rack all the way down and then raise each side of the rack individually until it clicks into place.
• Before pushing the upper rack into the dishwasher, ensure the rack height is the same on both sides. If the height is not the same on both sides, the dishwasher door will not shut and the upper spray arm will not connect to the water inlet.
  
  There is a 24 5 /8 inches (56 mm) gain in height when the upper rack is moved to the lower position.
• After adjusting the rack levels, check that the spray arms are free to rotate.
• With the lower position of the upper rack, check if the bottom part of upper rack including spray arm is not disturbing items on the lower rack.
• When the upper rack is in the lower position, push in the upper rack first, and the lower rack later.
• Pull out the lower rack first, and the upper rack later.
• Raise the upper rack without pushing the buttons on each side. Pushing the buttons when raising the rack will prevent the rack from locking into position.
• To set the rack to the middle position, it may be easier to lower the rack all the way down and then raise each side of the rack individually until it clicks into place

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.
   

NOTE

• After completion of the wash program, check whether the detergent was completely washed out.
• Some dishwasher detergent tablets may become stuck in the dispenser due to their excessive size. Tablets can be placed onto the base of the wash tub next to the filter before starting the cycle.
• Too much detergent can leave a film on dishes and in the dishwasher, resulting in poor wash performance.
• If dishwasher detergent tablets are used without liquid rinse aid, the dishes and dishwasher interior will have excessive moisture. Select the Extra Dry option for better drying performance.
• Using liquid rinse aid improves drying performance by allowing water to drain off of dishes after final rinse.
• Do not use detergent tablets for shorter wash cycles. The tablet may not dissolve completely, causing detergent residue on dishes and inefficient cleaning.
• Using a wash booster helps remove spots, residue, and the white film caused by hard water. It does not help remove excess detergent residue.

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

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.
   

NOTE

• Only use liquid rinse aid in the dishwasher.
• Do not overfill the rinse aid dispenser.
• Wipe off any spilled rinse aid around the dispenser.

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.

Refilling the Rinse Aid

How often the dispenser needs to be refilled depends on how often dishes are washed and the rinse aid setting used.

• The Rinse Aid icon flashes when more rinse aid is needed, unless the rinse aid dispenser setting is set to L0.

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.

Clogged Drain Air Gap or In-Sink Disposal

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
   

NOTE

• The drain air gap and disposal are external plumbing devices that are not part of the dishwasher.
• The warranty provided with the dishwasher does not cover service costs directly associated with the cleaning or repair of the external drain air gap and disposal.

Cleaning the Filters

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.
   

NOTE

• For best wash performance, clean the filter after each load. If food debris remains in the filter, it may cause an odor.
• In areas with hard water, clean the filter at least once a month with a soft brush.
• Clean the filters using non-abrasive materials and warm running water.
• Make sure the filter is assembled correctly before starting a cycle. When assembling, rotate it firmly until it clicks.

Recommended Filter Cleaning Schedule

Cleaning the Spray Arms

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.

Cleaning the Upper Spray Arm

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 /8 turn counter-clockwise and pulling down.

6. After cleaning the upper spray arm, press it up into place. Turn the nut 1 /8 turn clockwise to make sure that the nut locks back into place.
   
7. After assembly, check whether the spray arms rotate freely

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.
    NOTE 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 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.
