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 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.

WARNING
• Installation damage is not covered by the warranty, and leaks caused by improper installation may result in property damage.
• Do not use existing holes unless they are in the target area.
• Failure to properly locate the hole for the water and drain lines may prevent the dishwasher from installing flush with the cabinets and could result in kinked, pinched, crushed, stressed or damaged lines.

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 –73/4” (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.

WARNING

Water Connection

• Do not reuse an old hose. Use only a new hose when installing the dishwasher. The old hose could leak or burst causing flooding and property damage. Contact an LG Customer Information Center for assistance in buying a new hose.

Electrical Connection

  • Use a time-delay fuse or circuit breaker.
  • Operate this appliance with the correct voltage as shown in this manual and on the rating plate.
  • The wiring must be grounded properly. If in doubt, have it checked by a qualified electrician.
  • Connect the appliance using 3-wires, including a ground wire.
  • The appliance and outlet must be positioned so that the plug is easily accessible.
  • Do not use an extension cable or adapter with this dishwasher.
  • Do not overload the outlet with more than one appliance.
  • The included 16AWG wire nuts should be used.
  • It is the personal responsibility and obligation of the product owner to have a proper outlet installed by a qualified electrician.

CAUTION

  • When connecting the dishwasher water supply line to the house water supply, sealing tape or compound should be used on pipe threads to avoid leaks. Tape or compound should not be used on compression fittings.
  • Connect the dishwasher to a hot water supply with a temperature range between 120 °F (49 °C) and 149 °F (65 °C). This temperature range provides the best washing results and shortest cycle time. To prevent damage to dishes, the temperature should not exceed 149 °F (65 °C).
  • Water supply pressure must be between 20 psi and 80 psi (140–550 kPa). If the water supply pressure exceeds 80 psi, a pressure reducing valve must be installed. Otherwise premature failure of the inlet valve may occur.

Preparing Dishwasher

WARNING

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

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.
