Step 1 · Preparation and Planning

Begin by ensuring your work area is safe and prepared. Turn off the power to both the dishwasher and the garbage disposal at your home's main electrical panel (circuit breaker). Clear all items from the cabinet under the sink to give yourself ample room to work. Lay down old towels or place a shallow pan inside the cabinet to catch any water that will spill from the drain lines. Unpack your new dishwasher air gap kit and verify that all parts, including the body, decorative cover, washers, mounting nut, and hose clamps, are present.
