Does a Freestanding Dishwasher Need Plumbing?

The short answer is yes, a freestanding dishwasher needs plumbing. However, the plumbing requirements for a freestanding dishwasher are different from those of a built-in dishwasher. In this article, we will explain how a freestanding dishwasher works, what kind of plumbing it needs, and how to install it properly.

How a Freestanding Dishwasher Works

A freestanding dishwasher is a type of dishwasher that can be placed anywhere in the kitchen, as long as it has access to a power outlet and a water source. Unlike a built-in dishwasher, which is permanently fixed to the kitchen cabinets and connected to the sink drain, a freestanding dishwasher has its own water inlet and outlet hoses that can be attached to a faucet or a valve.

A freestanding dishwasher works by filling up a tub with water from the inlet hose, heating it up, and spraying it on the dishes with a rotating arm. The dirty water is then drained out through the outlet hose, and the cycle repeats until the dishes are clean. Some freestanding dishwashers also have a drying function that uses hot air or a fan to dry the dishes.

What Kind of Plumbing a Freestanding Dishwasher Needs

A freestanding dishwasher needs two kinds of plumbing: a water supply and a water drain. The water supply can be either a dedicated valve or a faucet adapter that allows the inlet hose to be connected to the kitchen faucet. The water drain can be either a sink drain or a standpipe that allows the outlet hose to be discharged into a drain pipe.

The plumbing for a freestanding dishwasher should be compatible with the size and type of the hoses that come with the appliance. The hoses should also be long enough to reach the water source and the drain without kinking or twisting. The hoses should also have a high loop or an air gap to prevent backflow or siphoning of dirty water into the dishwasher.

How to Install a Freestanding Dishwasher Properly

Installing a freestanding dishwasher properly is important to ensure its optimal performance and safety. Here are some steps to follow:

  • Choose a suitable location for the dishwasher, preferably near a power outlet and a water source. Make sure there is enough space for the dishwasher to open and close its door, and that it does not block any vents or outlets.
  • Plug the dishwasher into the power outlet and turn it on. Check the control panel and the display for any error codes or warnings. If there are any, refer to the user manual or contact the manufacturer for troubleshooting.
  • Connect the inlet hose to the water supply, either a valve or a faucet adapter. Make sure the connection is tight and secure, and that there are no leaks. Turn on the water supply and check the water pressure and temperature. The water pressure should be between 20 and 120 psi, and the water temperature should be between 120 and 150°F.
  • Connect the outlet hose to the water drain, either a sink drain or a standpipe. Make sure the connection is tight and secure, and that there are no leaks. Create a high loop or an air gap with the hose to prevent backflow or siphoning. The outlet hose should be at least 20 inches above the floor, and the drain pipe should be at least 1.5 inches in diameter.
  • Load the dishwasher with dishes according to the manufacturer’s instructions. Use the appropriate detergent and rinse aid for the dishwasher and the water hardness. Select the desired cycle and settings, and start the dishwasher. Monitor the dishwasher for any unusual noises or smells, and check the dishes for cleanliness and dryness after the cycle is complete.
