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 will need a 3″ x 13/

4″ 

(76 x 45 mm) opening through the cabinet to pass the dish-

washer water supply line through toward the shut off valve.

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.

The dishwasher drain hose may be connected to the house-

hold or field drain plumbing in one of four ways. You will need 

a 1¼" diameter hole in order to pass the drain hose through 

the cabinet.

 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: 

·  If local ordinance require an air gap, install it according 

to the manufacturer’s instructions.

·  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.

·  The dishwasher drain hose must have one place along 

its length that is securely attached 20″ (508 mm) above 

the cabinet floor.

·  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 150″ (3800 mm).
