DRAIN REQUIREMENTS

 

A new drain hose is supplied with your dishwasher. If drain 

hose is not long enough, use a new drain hose with a 

maximum length of 12 ft (3.7 m) that meets all current AHAM/

IAPMO test standards, is resistant to heat and detergent, and 

fits the 1" (25 mm) drain connector of the dishwasher. See 

the “Tools and Parts” section at the front of the guide for part 

details and orders.

 

Make sure to connect drain hose to waste tee or disposer 

inlet above drain trap in house plumbing and 20" (508 mm) 

minimum above the floor. It is recommended that the drain 

hose either be looped up and securely fastened to the 

underside of the counter or be connected to an air gap.

 

Make sure to use an air gap if the drain hose is connected 

to house plumbing lower than 20" (508 mm) above 

subfloor or floor.

 

If required, the air gap should be installed in accordance 

with the air gap installation instructions. When you are 

connecting the air gap, a rubber hose (not provided) will 

be needed to connect to the waste tee or disposer inlet.

 

Use 1/2" minimum I.D. drain line fittings.

WATER SUPPLY REQUIREMENTS

 

This dishwasher has a water heating feature and also  

requires a connection to a hot water supply line.

If installed in new construction, make sure the house 

water supply lines have been flushed prior to connecting 

the dishwasher to remove any debris that may exist in 

the supply line.
