Connecting the Hot Water Supply 
There are two plastic corrugated hoses that exit the 
back of the dishwasher. The larger hose, with the 
brass fitting on the end, is the water supply hose to 
the dishwasher (the other hose is the dishwasher 
drain hose). You wil  need a 3Ǝ x 1 

3/4Ǝ (76 x 45 mm) 

opening through the cabinet to pass the dish-washer 
water supply line through toward the shut off valve. 

 

Figure 9 

To connect the hot water supply: 
1. Assemble the water supply adaptor fitting (H) 

from the parts bag onto the dishwasher water 
supply hose. This connection does not require 
Teflon brand tape 

2. Pass the dishwasher water supply line with 

attached adaptor through the opening toward the 
water shut off valve. Take care not to allow the 
hose to kink or twist behind the dishwasher. 

3. Connect the dishwasher water supply line with 

adaptor to the water shut off valve. You will need 
to use an approved dishwasher water supply line 
with the correct fittings for this connection. 
Always use the appropriate seal when making 
plumbing connections. 
NOTE: The end of the dishwasher water inlet hose is 
heavy and will need to be supported. It is best to lay 
the end on the cabinet floor as shown in Figure 9

4. After all connections are made, turn on the hot 

water and check for leaks. 

Drain Connections 

The dishwasher drain hose may be connected to 
the house-hold or field drain plumbing in one of four 
ways. You will need a 11/4" diameter hole in order to 
pass the drain hose through the cabinet. 
1. Directly under the sink dishwasher drain 

connection, as shown in Figure 11

2. Directly to a disposer dishwasher drain 

connection, as shown in Figure 12

3. To the under sink dishwasher drain connection 

through an air gap, as shown in Figure 13

4. To a disposer dishwasher drain connection 

through an air gap, as shown on Figure 14

IMPORTANT NOTES: 
x If local ordinance require an air gap, install it 

according to the manufacturer’s instructions. 

x If the dishwasher drain hose is to be connected 

to a disposer dishwasher drain connection, 
remove the plug from the disposer’s dishwasher 
drain connection. 

x The dishwasher drain hose must have one place 

along its length that is securely attached 20Ǝ (508 

mm) above the cabinet floor. 

x The drain hose length can be extended if 

necessary. The maximum length of the drain 
hose, including the hose leading to the air gap, is 
150Ǝ (3800 mm).
