Portable dishwashers are useful appliances in kitchens that are tight on space. These appliances are typically used in apartments, RVs and mobile homes. They work by hooking up a hose to the hot water supply in your kitchen sink. Any nearby electrical outlet supplies the power, and a drain hose carries the dirty dishwater back to the kitchen sink.

Replacing a portable dishwasher hose isn’t difficult, and there are a number of vendors online where you can purchase one, if needed.

Turn of the Power

As with just about any other appliance repair project, the first step is to disconnect the appliance from the power grid. With a portable dishwasher, this is as simple as unplugging the dishwasher from the wall.

Disconnect the Hose from the Sink

Press the pressure relief button on the portable dishwasher hose if it is currently connected to the sink.

Disconnect the Hose from the Portable Dishwasher

Turn the portable dishwasher around so that you can see the hose on the back. Place a towel or rag on the ground underneath the dishwasher in case it leaks. Disconnect the hose from the back of the portable dishwasher by loosening the coupling counterclockwise. Use a pair of pliers, if needed. Pull the hose out of the back of the dishwasher.

Install the New Hose

Insert the end of thenew hose into the back of the dishwasher. Slide the coupling over the threads on the dishwasher and tighten.

Install a new dishwasher faucet adapter, if needed. If you’ve purchased the same size hose from the same manufacturer, this step is most likely not necessary. But if you find that your new portable dishwasher hose doesn’t fit into your present adapter, remove it and replace it with one that came with the new hose. These adapaters simply unscrew from the faucet spout threads counterclockwise. Insert a new adapter and turn clockwise. Connect the portable dishwasher hose to the adapter and secure.

Testing out the Replacement

Plug the portable dishwasher back into the nearest outlet. Ensure that the hose connections are tight. Turn on the hot water in the sink according to the instructions from your portable dishwasher manufacturer. Run a short load on the dishwasher. Watch the replacement hose as the cycle completes and make sure that there are no leaks. Tighten any couplings or adapaters, if needed. One you’re sure that everything is working correctly, you can rest easy.

One of the latest innovations in portable dishwashers is they are also being marketed as “convertable” dishwashers. This means that, should you move to a larger kitchen or find yourself with more room one day, you can easily make one of these portable dishwashers a permanent fixture.
