Product Dimensions
Back View
Side View
For easiest installation, see marked areas (1) for water and electrical
clearances in base of dishwasher. Water supply hose, drain hose and electric
cable should be passed through this area.
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.
Choosing the Proper Location
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
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.
WARNING
– 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.
Routing Water Supply Line and Electrical Wiring
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 mm – 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 mm – 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.
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
CAUTION
- If you lay the dishwasher on its back, do so carefully to avoid damaging the drain hose and the tub.
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 materials 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. See installation instructions in Securing Dishwasher to Cabinet Opening.
NOTE
- Installation brackets and screws can be found in the silverware basket.
1 Insert the tabbed end of the installation brackets into the slots in the upper frame. Rotate the brackets until the tabbed ends are facing up.

Leveling Dishwasher
Check that the dishwasher is level and adjust the leveling feet if necessary.
CAUTION
- Failure to level the dishwasher may result in leakage, problems closing the door, or noise.
- Where the cabinet opening is narrower than recommended (see Preparing Cabinet Opening ), the dishwasher must be carefully leveled and aligned so that the dishwasher is supported fully by the 3 leveling feet and is not hanging from the installation brackets. Failure to do so can result in leaks from the front of the dishwasher, AE errors, difficulty in closing the door, or failure to operate.
Checking Leveling
To check that the tub is level from front to back, remove the lower rack and pour 169 oz. (5 L) of water into the bottom of the tub. The water level should be near the center of both tub lower indentations at the front.
With the lower rack removed, place a level on the inside wall of the tub to check that the dishwasher is level from side to side.
- If you do not have a level, try using a smartphone level application instead.
Make sure that the gap between the tub walls and the door liner is the same on either side.
Adjusting Leveling Feet
Adjust as needed until the dishwasher is completely leveled.
- Adjust the front and rear leveling feet until they are all in firm contact with the floor. Failure to level the dishwasher may prevent the door from closing properly and the dishwasher will not turn on.
Adjusting Front Leveling Feet
Use a flat-blade screwdriver to turn the front leveling feet and adjust the
front of the tub.
- Turn the front leveling feet clockwise to raise the front of the tub and counterclockwise to lower it.
- The adjustments work identically for both front leveling feet.
- When a flat-blade screwdriver is unavailable, use a 1/4″ square drive wrench (1) or 3/8″ square drive wrench (2) with 1/2″ socket (3) to turn the front leveling feet and adjust the front of the tub.
Adjusting Rear Leveling Foot
Use a Phillips screwdriver to adjust the rear leveling foot and the rear of
the tub using the center screw at the base of the appliance in the front.
- Turn the center screw clockwise to raise the rear of the tub and counterclockwise to lower it.
NOTE
- To avoid damaging the screw, do not use an electric screwdriver.
Securing Dishwasher in Cabinet Opening
