How to Plumb in a Portable Dishwasher

Plumbing a portable dishwasher is a relatively easy task to complete, and you can save money by doing it yourself. Dishwashers most often connect to the sink drain to empty, and require a supply of hot water and electricity. Portable dishwashers are a convenient option for homeowners with small kitchens who do not want to be restricted to hand-washing dishes. Once dishwashing is complete, the appliance can quickly be moved out of the way.

Select the area where you wish to place the portable dishwasher. It should be close to the sink as well as an electrical socket.

Use a wrench to gently remove the small metal ring containing the screen from the faucet nozzle. Put it aside in an area where it is safe and can be readily located.

Locate the retractable hose on the back of the portable dishwasher. The hose will contain a faucet adaptor with a plastic ring. Pull down the plastic ring and slide the hose adaptor over the end of the faucet until it is tightly connected.

Plug the power cord into the electrical socket.

When ready to run a washing cycle, turn on the sink's hot water supply and start the dishwasher.


Most portable dishwashers have a water accumulation button on the side of the adaptor to release water that may be contained in the hose. Press the button to drain the water out of the hose before retracting it into the dishwasher.
