How to Convert a Portable Dishwasher to an Under-Counter

Pick a location for the portable dishwasher. The location must have a nearby electrical outlet that the cord on the unit can reach. Measure the size of the electrical cord. Drill a small hole in the side of the cabinet, leaving enough for the cord.

Drill a second hole through the cabinet wall, placing the hole in the wall next to the sink. Remove the water hose from the conversion kit and push it through the hole. Insert a tube-bending spring into the end of the tube. Place a ferrule on the end of the tube and tighten in place with a compression nut.

Turn the portable dishwasher around and check the back. It should have a small hole near the bottom or top for the water line. Unscrew any hardware on the threading and slip the water hose inside. Reattach the hardware and screw tightly.

Connect the drain line to the dishwasher, using the same steps you did for the water line. The drain line should attach to the back of the dishwasher and resemble a flexible hose or rigid PVC pipe.

Locate an inlet on the pipe under your sink. An inlet is a small piece of pipe that curves or branches off the main pipe. Remove the cover from the inlet and slip the drain line onto the pipe. Slide a hose clamp over the end and screw shut.

Run the water line to the hot water pipes that attach to the sink. Depending on the layout of your kitchen, this might require cutting into the wall before locating the hot water pipe. Remove the cover from an inlet branching off the hot water line. Attach a hose clamp, slip the hose into the inlet and screw closed.

Carefully push the portable dishwasher back inside the cabinet. Make sure that the hoses remain flat without crimping or bending. Push the electrical cord through the hole you drilled in the first step and plug into the wall before using.
