Preparing for Installation

Preparing the Drain

Keep the factory installed high loop drain hose in 

place to ensure proper dishwasher operation. Do 

not modify or move the mounting bracket in any 

manner. If it is necessary to lengthen the hose, 

install an aftermarket drain extension kit, available 

at most home improvement stores.

IMPORtANt: Should a drain hose longer than the 

one provided be required, use a hose extension 

approved for detergents and high temperature water. 

The drain hose supplied with the dishwasher meets 

an AHAM DW-1 test standard. Total drain hose length 

(including factory installed hose) must not exceed  

10 feet. (304.8 cm) from the top of the drain loop on 

the back of the unit. Joints and joint tubes must have 

a minimum inside diameter of 7/8” (2.2 cm).

•  The drain hose supplied with the dishwasher 

must be connected to a minimum 1/2” inside 

diameter drain connection.

•  The drain hose is equipped 

with a cone-shaped connector 

on the end that is ready to 

be cut to the desired drain connection size. Only 

a clamp (not provided) is required. It fits drain 

connections with an internal diameter of 1/2, 5/8, 

3/4 and 7/8 inches (1.3, 1.6, 1.8 and 2.2 cm).

•  You must install an air gap in the drain system 

if required by local codes. Plan for the air 

gap in the sink or countertop area adjacent to 

the dishwasher. A section of drain hose (not 

provided) needs to be installed from the air gap 

to the waste disposer inlet or waste tee.

•  If an air gap is not required, the drain hose must 

be installed to a disposer inlet or waste tee above 

the sink trap in the household plumbing.

•  For proper drainage, the drain line connection 

must be a minimum of 20” (50.8 cm) above the 

bottom of the dishwasher.

•  No part of the drain hose can be lower than the 

disposer or waste tee connection or higher than 

35” (88.9 cm) from the bottom of the dishwasher.
