LOCATION REQUIREMENTS
• Any built-in dishwasher must be fully enclosed on the top, sides, and back and must not support any part of the
enclosure. Therefore, the cabinet space below your countertop is the best location.
• The cabinet opening must be at least 23'' (58.4 cm) deep and 23.6'' (60 cm) wide and 32.5''-34.5'' (82.5 cm – 87.5
cm) high as shown in Figure A.
• If the dishwasher is to be installed in a corner, make sure there is an adequate clearance to open the door. A
minimum of 2” (5 cm) is required between the dishwasher and an adjacent wall, as shown in Figure B.
• Select a location as close to the sink as possible for easy connections to water and drain lines.
• To ensure proper drainage, the dishwasher should not be installed more than 10 feet (3 meters) from the sink.
• Do not install dishwasher over carpeted flooring.

1. Do local codes or ordinances require an air gap?
2. Will waste tee or disposer connection be less than 18" above the floor?
3. Will installation have a drain loop less than 32" above the floor?
If the answer to ANY of the 3 questions above is YES, Method 1 MUST be used. Otherwise, either Method 1 (Figure
C) or Method 2 (Figure D) may be used.

We recommend:
• A time-delay fuse or circuit breaker.
• A separate circuit.
Warning! No other appliances or outlets should be
connected to the dishwasher supply circuit.
Connecting the Power cord
• One end of the Power cord is already attached to the
dishwasher. Plug the other end (the plug) into a
grounded 3 prong outlet located on an adjacent wall or
cabinet. The outlet must meet all local codes and
CABINET PREPARATION
Drill a 14⁄5" diameter hole in the cabinet (Figure E)
on the right-hand side or rear of the cabinet. For
wood cabinets, sand the hole until smooth. For
metal cabinets, cover the edge with a grommet.
WARNING! THESE INSTALLATION INSTRUCTIONS ARE INTENDED FOR USE BY QUALIFIED PROFESSIONALS.

WATER SUPPLY REQUIREMENTS
Installing the water supply line
NOTE: The water supply hose is located inside the tub.
1. Turn off the water supply.
2. Install a hand shut-off valve in an accessible location,
such as under the sink. (Optional, but strongly recommend-
ed, and may be required by local codes.)
3. As shown in Figure F, connect one end of the inlet line
(A) to the 3/4-inch FHT (B) and connect to the dishwasher.
4. Run the other end of the inlet line through the hole in the
cabinet. If the shut-off valve is 3/8 inch I.D, the inlet line can
be directly connected to the shut-off valve.
5. Adjust the water heater so that it delivers water
temperature between 120°F (49°C) and 150°F (65°C).
6. Flush the water line to clean out debris.
Important! Make sure there are no sharp bends or kinks in
the water line, which might restrict water flow.
Figure F

If a longer drain hose is required, add up to 42'' (1
meter) of length for a total of 10 ft. (3 meters) to the
factory-installed hose. Use 5/8'' (1.6 cm) or 7/8'' (2.2
cm) inside diameter hose and a coupler to connect
the two hose ends. Secure the connection with hose
clamps.
NOTE: TOTAL DRAIN HOSE LENGTH MUST NOT
EXCEED 10 FEET (3.6 METERS) FOR PROPER DRAIN

STEP 10
Perform a PRE-TEST by reviewing this list after install-
ing your dishwasher:
• Check to be sure the power is OFF.
• Open the door and remove all foam and paper pack-
aging.
• Read the Instruction Manual for operating instruc-
tions.
• Check the door opening and closing. If the door does
not open and close freely or tends to fall, check spring
adjustments.
• Make sure that the wiring is secure under the dish-
washer, not pinched or in contact with other compo-
nents.
• Check door alignment with tub. If the door hits the tub,
level the dishwasher.
• Pull the lower rack out about halfway. The rack should
not roll back or forward on the door. If the rack moves,
adjust the leveling legs.
• Check door alignment with the cabinet. If the door hits
the cabinet, reposition or relevel the dishwasher.
• Make sure that the water supply and drain lines are
not kinked or in contact with other components. Contact
with the dishwasher frame could cause noise.
• Turn on the sink hot water faucet and verify water
temperature.
• Incoming water temperature must be between 120°F
(49°C) and 150°F (65°C). A minimum of 120°F (49°C)
temperature is required for best wash performance.
• Turn on the water supply. Check for leaks. Tighten
connections if needed.
STEP 11
Perform the WET-TEST by following these instruc-
tions:
• Plug the power cord into the outlet.
• Power on and select the “Rinse” wash program.
• Close the door and press the “Start” button.
• Check to be sure that water enters the dishwash-
er. If water does not enter the dishwasher, check if
the water and the power are turned on.
• Check for leaks under the dishwasher. If a leak is
found, turn the power supply off, then tighten
connections. Restore power after the leak is
corrected.
• Check for leaks around the door. A leak around
the door could be caused by door rubbing or hitting
against adjacent cabinetry.
• Reposition the dishwasher if necessary.
• The dishwasher will drain and turn off about 10
to 12 minutes after the first fill. Check the drain
lines. If leaks are found, turn the power off at the
breaker and correct plumbing as necessary.
• Restore power after corrections are made.
• Open the dishwasher door and check if most of
the water has drained. If not, check the drain line for
kinks.
• Run the dishwasher through another fill and
drain cycle.
• Check for leaks and correct if required.
• At the end of the drain, open the door and press
the “Power off” button.
