KitchenAid Undercounter Dishwasher Installation and Dimensions
Product Model Numbers
KDTF324PPA, KDTF924PPS, KDTF924PPA
Drain Requirements
A new drain hose is supplied with the dishwasher. If the drain hose is not long enough, use a drain hose extension with a maximum length of 12 ft (3.7 m).
Connect the drain hose to a waste tee or disposer inlet above the drain trap in house plumbing, at least 20" (508 mm) above the floor. It is recommended to loop the drain hose and securely fasten it to the underside of the counter or connect it to an air gap.
IMPORTANT: This product is not equipped with a high loop on the side of the dishwasher. The installer is responsible for adding a high loop in the adjacent cabinet if the dishwasher drains into a floor drain. This prevents water draw-off during operation. A high loop is generally not required if the drain is connected to a sink drain, counter-top air-gap, or disposer. An internal check valve prevents back-flow.
Use an air gap if the drain hose is connected to house plumbing lower than 20" (508 mm) above the subfloor or floor.

A visual representation shows an air gap connected to a faucet and drain pipe. The air gap is a vertical pipe with an opening at the top.
If an air gap is required, install it according to its installation instructions. A rubber hose (not provided) is needed to connect to the waste tee or disposer inlet.
Use 1/2" (13 mm) minimum I.D. drain line fittings.
Water Supply Requirements
This dishwasher may be fitted with a smart inlet hose with a water cut-off valve. Do not cut the water inlet hose for any reason.
The dishwasher has a water heating feature and requires a connection to a hot water supply line.
A hot water line with 20 psi to 120 psi (138 kPa to 862 kPa) water pressure is recommended. Verify with a licensed plumber.
Water temperature should be 120°F (49°C) at the dishwasher.
Use 3/8" (9.5 mm) O.D. copper tubing with compression fitting or flexible braided water supply line.
Electrical Requirements
Ensure the electrical connection and wire size are adequate and conform to the National Electrical Code, ANSI/NFPA 70 - latest edition, and all local codes and ordinances.

We Recommend:
Install the dishwasher on a circuit with appropriate interrupter per your local code. The dishwasher is compatible with time delay fuses, standard circuit breakers, and GFCI and AFCI circuit breakers.
Circuit Requirement:
The dishwasher may be installed on the same circuit as a garbage disposal, provided the branch circuit load does not exceed the rated circuit load and complies with all governing codes and regulations, including the National Electrical Code, ANSI/NFPA 70 - latest edition.
No electrical connections other than the dishwasher power and ground connections can be made inside the dishwasher junction box.
If Connecting Dishwasher with a Power Cord:
- Use a UL Listed power cord kit marked for use with dishwasher. Refer to the Owner's manual for part details.
- Plug into a grounded 3-prong outlet that meets all local codes and ordinances.
If Connecting Dishwasher with Direct Wiring:
- Use flexible, armored, or nonmetallic sheathed copper wire with grounding wire that meets wiring requirements for your home and local codes and ordinances.
- Use only the supplied plastic cable fittings for flexible and non-metallic sheathed wiring. Do not use metallic strain reliefs for these wire constructions.
- Use a UL-listed/CSA-approved metallic strain relief for armored cable installations (21 mm diameter), following the manufacturer's installation instructions.
