Grounding Instructions–Permanent Connection
This appliance must be connected to a grounded metal, permanent wiring system, or an equipment-grounding conductor must be run with the circuit conductors and be connected to the equipment-grounding terminal or lead on the appliance.

Grounding Instructions–Power Cord Models
This appliance must be grounded. In the event of a malfunction or breakdown, grounding will reduce the risk of electric shock by providing a path of least resistance for electric current. This appliance is equipped with a cord having an equipment-grounding conductor and
a grounding plug. The plug must be plugged into an appropriate outlet that is installed and grounded in accordance with all local codes and ordinances.

WARNING

The improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service representative if you are in doubt that the appliance is properly grounded. Do not modify the plug provided with the appliance; if it will not fit the outlet, have a proper outlet installed by a qualified technician.

Cabinet Preparation & Wire Routing

• The wiring may enter the opening from either side, rear or the floor within the shaded area illustrated above in figure and as defined in PREPARE DISHWASHER ENCLOSURE section.
• Cut a 1-1/2″ maximum diameter hole to admit the electrical cable. Edges of hole should be smooth and rounded. Permanent wiring connections may pass through the same hole as the drain hose and hot water line, if convenient. If cabinet wall is metal, the hole edge must be covered with a bushing.

NOTE: Power cords with plug must pass through a separate hole in the cabinet.

Electrical Connection to Dishwasher
The electrical connection is on the right front of the dishwasher.

• For permanent connections, the cable must be routed as shown in the figure. The cable must extend a minimum of 24″ from the rear wall.
• For power cord connections, install a 3-prong grounding-type receptacle in the sink cabinet rear wall, 6″ min. or 18″ maximum from the opening, 6″ to 18″ above the floor.
• Use only WX09X70910 (5’ 4” long) or WX09X70911 (7’ 9” long) Dishwasher Power Cord Kit. Do not use an extension cord or adapter plug with this appliance.

PREPARE A HOT WATER LINE

NOTE: GE Appliances recommends copper tubing for the waterline, but if you choose to use flexible hose, use GE Appliances WX28X326, flexible braided hose.

• The water supply line (3/8” copper tubing or flexible braided hose) may enter from either side, rear or floor within the shaded area shown in the figure.
• The water supply line may pass through the same hole as the electrical cable and drain hose. Or, cut an additional 1-1/2″ diameter hole to accommodate the water line. If a power cord with plug is used, water line must not pass through power cord hole.

WATERLINE CONNECTION

• If using a flexible braided supply hose, label the hose with the installation date to use as reference. Flexible braided hoses, elbows and gaskets should be replaced in 5 years.
• Turn off the water supply.
• Install a hand shut-off valve in an accessible location, such as under the sink. (Optional, but strongly recommended and may be required by local codes.)
• Water connection is on the left side of the dishwasher. Install the hot water inlet line, using no less than 3/8” copper tubing or a flexible braided hose. Route the line as shown in PREPARE HOT WATER LINE and extend forward at least 19” from rear wall.
• Adjust water heater for 120°F to 140°F temperature.
• Flush water line to clean out debris.

Dishwasher Installation

CHECK DOOR BALANCE

CAUTION

Opening the door will cause the dishwasher to tip forward when it is not fully installed. When opening the door prior to the dishwasher being fully installed, hold the top of the dishwasher securely with one hand and hold the door with the other hand. Gloves should be worn.

To check the door balance, hold the top of the dishwasher firmly.

• Check the door balance by opening and closing the door.
• If the door drops when released, increase the spring tension. If the door rises when released, decrease the spring tension.

ADJUST LEVELING LEGS

• Move the dishwasher close to the installation location and lay it on its back. NOTE: Do not place the dishwasher on its side.
• Measure installation height and dishwasher height. Extend leveling legs out from the dishwasher base, 1/2” less than installation height.

REMOVE TOEKICK

Remove the 4 to kick screws and the 2-piece toekick. Set aside for use in Step 19.

INSTALL POWER CORD

Skip this step if the dishwasher will be permanently connected to the house electrical system or has a factory-installed power cord.

• The power cord and connections must comply with the National Electrical Code, Section 422 and/or local codes and ordinances. Maximum power cord length is 6 feet. Power Cord Kit WX09X70910 or WX09X70911, available for purchase from an authorized
  GE Appliances dealer meets these requirements.

• Remove junction box cover.

• Install strain relief in the junction box bracket.

• Insert the power cord through the strain relief and tighten.

• Make sure black, white and green dishwasher wires are threaded through the hole in the junction box bracket.

• Connect power cord white (or ribbed) to dishwasher white, black (or smooth) to dishwasher black and ground to dishwasher green wire. Use UL-listed wire nuts of appropriate size.

• Replace junction box cover using the screw. Be sure wires are not pinched under the cover.

INSTALL 90° ELBOW

• Ensure rubber gasket is located between valve and elbow.
• Thread 90° elbow onto the water valve.
• Do not overtighten elbow. Water valve bracket could bend or water valve fitting could break.
• Position the end of the elbow to face the rear of the dishwasher.

POSITION WATER LINE AND HOUSE WIRING

• Position the water supply line and house wiring on the floor of the opening to avoid interference with base of dishwasher and components under the dishwasher.

INSTALL DRAIN HOSE, THROUGH CABINET

• Stand the dishwasher upright and position it in front of cabinet opening. Insert drain hose into the hole in cabinet side. If a power cord is used, guide the end through a separate cabinet opening.

Tip: Prevent unnecessary service call charges for fill, drain or noise concerns.
Position utility lines so they do not interfere with anything under or behind the dishwasher.

CONNECT DRAIN LINE

The molded end of the drain hose will fit 5/8” through 1” diameter inlet ports on the air gap, waste tee or disposer.

• DRAIN CONNECTION HEIGHT IS NOT TO EXCEED 72” ABOVE THE BOTTOM OF THE DISHWASHER.
• TOTAL DRAIN HOSE LENGTH MUST NOT EXCEED 12 FEET FOR PROPER DRAIN OPERATION.

CONNECT DRAIN LINE (CONT.)

Connect drain line to air gap, waste tee or disposer using the previously determined method. Secure hose with a screw-type clamp.

Method 2 – “High drain loop” with waste tee or disposer
Fasten drain hose to the underside of the countertop with a hanger.

IMPORTANT – Either one of the above methods must be used or dishwasher will not operate properly.

IMPORTANT – When connecting drain line to the disposer, check to be sure that drain plug has been removed. THE DISHWASHER WILL NOT DRAIN IF THE PLUG IS LEFT IN PLACE.

Tip: Avoid unnecessary service call charges for a no-drain complaint.
Make sure the excess drain hose has been pulled through the cabinet opening. This will prevent excess hose in the dishwasher cavity from becoming kinked or crushed by the dishwasher.

INSTALL MOUNTING BRACKETS

You will need the mounting brackets and 4 of the Phillips-Head screws set aside in the PREPARATION section.
You must install the mounting brackets onto the dishwasher tub frame top OR sides prior to sliding the dishwasher into place under the countertop. The mounting brackets have several available attachment positions to accommodate different cabinet constructions.

TOP MOUNTING OPTION
Install mounting brackets on top if the underside of the countertop is wood or wood-like material that accepts screws:
IMPORTANT – After installing brackets and before closing the dishwasher door, adjust the brackets by bending them up as needed, so that they do not contact the top of the dishwasher door and cause damage.
Top Mounting for 18” Models Only

•  If you are installing the dishwasher under a counter with a short overhang, the countertop brackets may extend beyond the edge of the counter. If this is the case, remove the excess length by repeatedly bending the brackets at the front notch only until they break.

SIDE MOUNTING OPTION
Install mounting brackets on sides if the countertop is granite or similar material that will not accept wood screws:

• Break off front portion of the tab with pliers at the location shown, prior to attaching to dishwasher.
• Position the left-hand side bracket as shown. Repeat with the right bracket.

Bend and break at cutout slots in brackets
(if/as necessary) on both sides before installing.

SLIDE DISHWASHER PARTIALLY INTO CABINET

IMPORTANT – Do not push against the front panel with your knees. Damage will occur.

• As you proceed, pull the drain hose through the opening under the sink. Stop pushing when the dishwasher extends about 6 inches forward of adjacent cabinets.
• Make sure drain hose is not kinked under or behind the dishwasher.
• Make certain the house wiring, drain line, and water line do not interfere with components under the dishwasher.

POSITION DISHWASHER UNDER COUNTERTOP

• Push the dishwasher into the cabinet.
• Push the sides with your hands. Do not use your knee against the door since door damage will occur.
• Carefully open and close the door to ensure that the door panel does not catch or rub on the cabinet frame.
• If the door catches or rubs on the frame, reposition and/or level the unit (see Step 14) until the door moves freely and does not contact the cabinet frame.

Tip: Prevent unnecessary service charges. Verify dishwasher is leveled.
Pull the dish racks half way out. They should stay put. Open and close the door. The door should fit in the tub opening without hitting the side of the tub. If the racks roll on their own, or the door hits the side of tub, re- level the dishwasher.

IMPORTANT – After leveling, verify that the dishwasher is still in the correct position shown in Step 11.

SECURE DISHWASHER TO COUNTERTOP OR CABINET

IMPORTANT – Prevent door panel and control panel damage. The dishwasher must be positioned so the front panel and control panel do not contact the adjacent cabinets or countertop. Mounting screws must be driven straight and flush. Protruding screw heads could scratch the door panel or control panel and interfere with door operation.
Method 1 Secure dishwasher to underside of wood countertop.

Method 2 Secure dishwasher to cabinet sides.

• Remove plug buttons from the tub. Do not discard.
• Fasten the dishwasher to the adjacent cabinets with the 2 Phillips-Head screws provided. Refer to the figure. Make certain screws are driven straight and flush to prevent panel damage. Do not screw into the cabinet face frame.
• Re-install plug buttons.
• Re-check that the dishwasher is square and level at both the top and bottom of the cabinet opening, with no twisting or distortion of the tub or door after mounting to the cabinets/countertop. Adjust if necessary.
• Confirm all leveling legs are in contact with the floor to prevent the dishwasher from rocking and ensure proper door and latch operation.
• When step is complete, close dishwasher door and verify that gap between countertop and top of dishwasher door is at least 1/2”.

PRETEST CHECKLIST
