How to Hook Up a Portable Dishwasher


A portable dishwasher may be the ideal solution for compact kitchens where an installed appliance is impractical and the residents loathe dishpan hands. These wheeled units can roll out from a closet or pantry to connect to the sink faucet with a threaded nozzle in a couple of minutes. Portable dishwashers are typically equipped with a retractable power cord on a spring-loaded reel to withdraw the cord inside the appliance when not in use. Just place the exhaust hose in the sink where it can drain.

Things You'll Need

  • Pliers
  • Push the portable dishwasher over to the kitchen sink with the loading door to the appliance facing outward.

  • Unscrew the cap on the end of the kitchen faucet by turning clockwise, then set the part on the counter. It will be needed later.

  • Attach the threaded coupler on the end of the dishwasher's feeder hose to the kitchen faucet by twisting the coupler counter-clockwise to the threads on the faucet. Turn on the water and tighten the faucet connection gently with pliers, if necessary, to stop any leaks.

  • Adjust the water temperature on the faucet to hot. Some portable dishwashers are equipped with built-in elements to heat the water and preserve hot water in the residential water tank, so this step may not be necessary, depending on the model.

  • Place the dishwasher exhaust hose in the sink and make sure the sink trap is clear of debris so water can drain properly.

  • Connect the dishwasher's electrical cord to a power outlet, then select the washing cycle and press the "Start" button or turn a dial control to the "Start" position.

Tips & Warnings

  • Connect hoses to the faucet and sink before plugging in the electrical cord.
