How to Install a Dishwasher

Step-by-step

1. 1

   Shut off water and power

   Close the hot supply valve under the sink and flip the dishwasher breaker off. Verify with a tester.

2. 2

   Attach the 90° elbow and supply line

   Wrap threads with 2 wraps of Teflon tape. Attach a 90° brass elbow to the water inlet, then the braided supply line.

3. 3

   Position the drain hose

   Route drain hose to the sink drain or disposal. Make a HIGH LOOP secured to the underside of the counter — this prevents siphon backflow.

4. 4

   Wire electrical

   Most 2026 dishwashers hardwire under the toe-kick. Match black to black, white to white, ground to ground. Cap and secure.

5. 5

   Slide in, level, secure

   Push into the cabinet opening. Level side-to-side and front-to-back using leg adjusters. Secure to the countertop or side cabinets with the included brackets.

6. 6

   Turn on and test

   Open water, restore power, run a rinse cycle. Check under-sink connections and toe-kick for leaks at 5, 15 and 30 minutes.
