Dacor DDW24S User Manual

4.  Once the dishwasher is in place check to make 

sure all slack is pulled out of the power cable, 

water supply line and drain hose. Check to make 

sure none of them are pinched or kinked.

NOtE: Do not attach the mounting screws until after 

Verifying Operation.

Water Line Connection

•  The unit has a float switch in the base pan 

to protect against flooding. If the inlet valve 

connection on the dishwasher is not seated 

properly, water may leak into the base pan and 

activate the float switch.

•  To avoid water leaks, use only the water supply 

line provided with the dishwasher.

1.  Before connecting the water supply line, make 

sure the water pressure and flow rate meet the 

specifications on page 4.

2.  Flush the water supply line prior to connecting it 

to the dishwasher’s water supply line.

3.  Insert the provided “O” ring in the end of the 

water supply line. 

Make sure it is 

evenly seated on 

the end of the 

tubing.

4.  Connect the end of the water supply line to the 

water line. Tighten the connection by hand plus a 

quarter turn with a crescent wrench.

Drain Line Connection

•  For proper dishwasher operation and drainage, 

the drain line must be routed through the bottom 

of the cabinet and up to the drain or air gap 

connection. The drain hose or air gap outlet 

must connect above the sink trap.

•  If required, the air gap must be installed at 

countertop level.

1.  If the drain will connect to a waste disposer, 

see the disposer manufacturer’s installation 

instructions for correct drain hose mounting 

techniques. Most disposers have a plug on the 

drain line connection that must be removed prior 

to attaching the drain line. Also, any joints must 

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

2.  Cut the drain hose adapter on the end of the 

drain hose to the appropriate size for the air 

gap, waste tee, disposer 

connection or hose extension.

Installation Instructions

3.  Connect the drain hose to the air gap or directly 

to the waste tee or disposer above the sink trap 

as shown in one of the examples on page 6. 

4.  Tighten the holding clamp.
5.  For installations with an air gap, make sure that 

the drain line between the air gap and the waste 

tee or disposer is in place and that it is clamped 

tightly on both ends.

6.  To ensure proper operation, inspect the drain 

system to make sure that: 
•  No part of the drain hose is higher than 35” 

(88.9 cm) from the bottom of the dishwasher.

•  The connection to the waste tee or disposer is 

a minimum of 20” (50.8 cm) above the bottom 

of the dishwasher base.

Verifying Operation

Pre-verification Check List

1.  Confirm that the power to the dishwasher is shut 

off at the circuit breaker panel.

2.  Make sure all packing material has been 

removed from inside the dishwasher.

3.  Familiarize yourself with operation of the 

dishwasher by reading the use and care manual.

4.  Remove any protective film, if present from the 

control panel, door panel, etc.

5.  Check again that the entire length of the power 

cable, water line and drain hose are free of 

pinches or kinks.

6.  Verify that the dishwasher is level front to back 

and side to side inside the cutout. Re-level if 

necessary before testing the unit.

Wet Test Checklist

1.  Turn on the water supply and wait for five 

minutes. Check for leaks. Tighten connections 

if necessary. 

NOtE: Improper installation of the 

water supply line “O” ring can cause the water 

line to leak at the connection.

2.  Turn on power to the dishwasher at the circuit 

breaker panel or fuse box. Make sure the power 

cord is connected to the electrical outlet (if 

applicable).

3.  Test dishwasher operation by running a 

and Hold cycle (which takes about six minutes). 

See the use and care manual for specific 

operating instructions. Check to make sure that 

the dishwasher takes in water and drains.
