Where should Whirlpool dishwasher be installed?

Do not run drain lines, water lines, or electrical wiring where they can interfere with or contact dishwasher motor or legs.

The location where the dishwasher will be installed must provide clearance between the motor and flooring. The motor should not touch the floor. Do not install dishwasher over carpeted flooring.

Shelter dishwasher and water lines leading to dishwasher against freezing.

1. easy access to water, electricity, and drain.

2. convenient access for loading and unloading dishes. Corner locations require a 2″ (5.1 cm) minimum clearance between the side of the dishwasher door and the wall or cabinet.

3. square opening for proper operation and appearance.

4. cabinet front perpendicular to the floor.

5. level floor. (If the floor in front of the opening is not level with the floor at the rear of the opening, shims may be needed to level the dishwasher.)

NOTE: To avoid shifting during dishwasher operation, shims must be securely attached to the floor.

If dishwasher will be left unused for some time or in a location where it may be subject to freezing, have it winterized by authorized service personnel. Make sure pipes, wires, and drain hoses are within the shaded area.

If the floor in the dishwasher opening is uneven (for example tile flooring only partway into the opening), you will need to be exact in measuring dimensions and in leveling the dishwasher.

How to install whirlpool dishwasher step-by-step

Step1.

1. Disconnect power.

2. Turn off the water supply.

Step2. install whirlpool dishwasher drain hose

Always use a new drain hose when installing a new replacement dishwasher.

1. Drill a 1¹⁄₂” (3.8 cm) diameter hole in the cabinet wall or floor on the side of the opening closest to the sink.

2. Connect drain hose to waste tee or waste disposer using one of the following methods:

  • Option 1, Waste disposer – with air gap
  • Option 2, No waste disposer – with air gap
  • Option 3, Waste disposer – no air gap*
  • Option 4, No waste disposer – no air gap

*An air gap is recommended.

To reduce the vibration of the hose, keep the hose away from the floor and the edge of the hole where it passes through the cabinet.

Option 1, Waste disposer – with air gap:

1. Remove the disposer knockout plug. Cut the end of the drain hose if needed (do not cut ribbed section).

2. Attach drain hose to air gap with the large spring-type clamp. If the drain hose was cut, use a 1¹⁄₂” to 2″ (3.8 to 5 cm) screw-type clamp*.

3. Use a rubber hose connector* with spring- or screw-type clamps* to connect the air gap to the disposer inlet.

This connection must be before the drain trap and at least 20″ (50.8 cm) above the floor where the dishwasher will be installed.

4. Insert drain hose through a hole cut in the cabinet to the front center of the opening where drain connection will be made.

Option 2, No waste disposer – with air gap:

1. Cut the end of the drain hose if needed (do not cut the ribbed section).

2. Attach drain hose to air gap with a large spring-type clamp. If the drain hose was cut, use a 1¹⁄₂” to 2″ (3.8 to 5 cm) screw-type clamp*.

3. Use a rubber hose connector* with spring- or screw-type clamps* to connect air gap to waste tee.

This connection must be before the drain trap and at least 20″ (50.8 cm) above the floor where the dishwasher will be installed.

4. Insert drain hose through a hole cut in the cabinet to the front center of the opening where drain connection will be made.

Option 3, Waste disposer – no air gap:

1. Remove the disposer knockout plug. Do not cut the end of the drain hose.

2. Attach drain hose to disposer inlet with the large spring-type clamp.

This connection must be before the drain trap and at least 20″ (50.8 cm) above the floor where the dishwasher will be installed.

It is recommended that the drain hose be looped up and securely fastened to the underside of the counter.

3. Insert drain hose through the hole cut in the cabinet to the front center of the opening where drain connection will be made.

Option 4, No waste disposer – no air gap:

1. Cut the end of the drain hose if needed (do not cut the ribbed section).

2. Attach drain hose to waste tee with 1¹⁄₂” to 2″ (3.8 to 5 cm) screw-type clamp*.

This connection must be before the drain trap and at least 20″ (50.8 cm) above the floor where the dishwasher will be installed.

 It is recommended that the drain hose be looped up and securely fastened to the underside of the counter.

Insert drain hose through the hole cut-in cabinet to the front center of the opening where drain connection will be made.

Step3. Install whirlpool dishwasher  water line

Tip: Routing the waterline through the left side of the cabinet opening will make water connection easier.

1. Drill a minimum ¹⁄₂” (1.3 cm) hole in the cabinet side, rear, or floor.

2. Measure the overall length of copper tubing required.

 3. Attach copper tubing to the waterline with a manual shutoff valve.

4. Slowly feed copper tubing through the hole in the cabinet.

Copper tubing will bend and kink easily, so be gentle. The copper tubing should be far enough into the cabinet opening to connect it to the dishwasher inlet on the front left of the dishwasher.

5. Turn the water shutoff valve to the “ON” position. Flush water into a shallow pan to get rid of particles that may clog the inlet valve.

6. Turn shutoff valve to “OFF” position.

Step4. Prepare whirlpool dishwasher

Tip: Put cardboard under dishwasher until it is installed in cabinet opening. The cardboard will help avoid damage to floor covering during installation.

1. Using 2 or more people, grasp the sides of the dishwasher door frame and put the dishwasher on its back, resting on top of the corner posts.

2. Remove the 2 top screws and the 2 bottom screws attaching the access panel and lower panel to the dishwasher using a ¹⁄₄” hex socket, nut driver, or Phillips screwdriver.

3. Remove panels and set panels aside on a covered surface.

4. Check that the grounding clip is attached to the lower panel.

5. Slide nut and ferrule onto the tubing.

  • Copper tubing only: Slide nut, then ferrule, about 1″ (2.5 cm) onto copper tubing.

NOTE: To avoid vibration during operation, route the water supply line so that it does not touch the dishwasher base, frame or motor.

6. Add 90° elbow fitting to the water supply line.

  • Connect the ³⁄₈” compression fitting to the water supply line prior installing the unit into the cabinet opening.
  • Attach such that the ³⁄₄” connection is facing upward.
  • Copper tubing only: Put the tubing into the 90° elbow fitting as far as it will go (the copper tubing bends and kinks easily).
  • Slide the nut and ferrule forward and start the nut onto the elbow threads.
  • Flexible braided connection: Secure nut to elbow using ⁵⁄₈” open-ended wrench or adjustable wrench.

NOTE: Do not use Teflon®† tape with compression fittings.

7. Remove terminal box cover.

8. measure the height of the cabinet opening for the underside of the countertop to the floor where the dishwasher will be installed (you need the lowest point).

  • Check chart for that height opening.
  • Put wheels in the required position.

9. Turn both front leveler legs to the same height.

If the minimum cutout height is less than 34″ (86.4 cm), the rear wheels can be removed for additional clearance. This will allow the dishwasher to fit into a 33⁷⁄₈” (86 cm) high cutout, but the dishwasher will be more difficult to move into position.

If the wheels are removed, cover the floor when moving the dishwasher.

10. Using 2 or more people, stand the dishwasher up.

NOTE: Do not attach the dishwasher. This will be done later.

Step5. Check door spring tension

With another person holding the dishwasher to keep it from tipping, open and close the door a few times. If the door closes or falls open under its own weight, the door tension will need to be adjusted.

  • If the door closes too quickly, decrease the spring tension by moving the spring end toward the front of the dishwasher.
  • If the door falls open, increase the spring tension by moving the spring end toward the back of the dishwasher.
  • Springs should be in the same notches on left and right sides.

Step6. Move whirlpool dishwasher into cabinet opening

1. Using two or more people, stand the dishwasher up.

 2. Grasp the sides of the dishwasher at the edges of the door panel.

3. Tilt dishwasher backward on wheels and move dishwasher close to cabinet opening. Do not push on the front of the panel or on the console, they may dent.

4. If the dishwasher has a power supply cord, insert the power supply cord into the hole cut into the cabinet. If using direct wire, check that it is on the right front side of the opening.

5. Check that the water line is on the left side of the opening and the drain hose is near the center of the hole in the cabinet.

6. Slowly move the dishwasher completely into the cabinet opening.

  • Do not kink or pinch copper tubing, drain hose, power supply cord or direct wire between dishwasher and cabinet.

Helpful Tip: Once the dishwasher is in position, you may have to support the front of the dishwasher by raising, lowering, or shimming the front feet.

7. Remove the cardboard from under the dishwasher.

8. Using the precut slots in the insulation, attach the insulation to the sides of the tub using the molded hooks on each side of the tub.

NOTE: It is all right if the dishwasher fits tightly into the cabinet opening.

  • Do not remove insulation blanket, the blanket reduces the sound level.

Step7. Level whirlpool  dishwasher

1. Align the front of the dishwasher door panel with cabinet doors. You may need to adjust the alignment to be even with your cabinets.

Helpful Tip: Prop up one side of the frame to hold dishwasher up off the floor when adjusting front legs.

With some installations, it may be easier to adjust the front leg using the ³⁄₁₆” hex head.

2. Check that leveling legs are firmly against the floor.

3. Close and latch the door.

4. Place the level against the front of the dishwasher to check that it is vertically aligned. If needed, adjust leveling leg or add shims under the rear wheel until the dishwasher.

5. Repeat for another side of the dishwasher.

NOTE: Shims must be securely attached to the floor to prohibit their movement when the dishwasher is operated.

6. Place level against top front opening of tub.

7. Check that dishwasher is level from side to side.

  • If dishwasher is not level, adjust front legs up or down until dishwasher is level.
