How to Hook Up a Stackable Washer & Dryer

A stackable washer and dryer, when set into place, is an extremely heavy appliance. Hooking up the washer and dryer to water and air vents is not something you'll want to do more than once because of the difficulty in moving the appliances. Fortunately, the hookup process is simple and can be done quickly and efficiently. Most washers and dryers operate on the 120-volt outlets supplied in most household laundry rooms. In addition, as long as your home has sufficient water pressure of 60 pounds per square inch, you can make the connections without needing to run a new pipe, or wire a single outlet.

A stackable washer and dryer saves space and adds convenience to any laundry room.
  1. Cut the power leading to the installation area from the circuit breaker.

  2. Place the washing machine in the final installation spot and use a carpenter's level to check that the washer is level. Adjust the feet on the bottom of the washer to make it level by turning them in place to reduce or extend the feet from the body of the machine. With help, place the dryer on top of the washer. Screw the two units together.

  3. Attach the water hoses to the washer, taking care to attach the water from the hot faucet in your home to the hot intake in your washer and from cold faucet to cold intake. Wrap the ridges of the connector with a layer of silicone tape before attaching the hoses to prevent leaks at the attachment points. Attach the water suppression valve if present, and then attach the drainage pipe from the washer to the drain in your laundry room, running it over the edge of the laundry sink, or attaching it to an existing drainage system in the room.

  4. Test the washer installation by turning on the power from the circuit breaker, and then turning on the water valves. Run the washer through a cycle.

  5. Cut the power again and then connect the dryer. Connect the gas line of a gas dryer to the shutoff valve, securing the connection with tape made for gas installations. Connect the gas line to the dryer and check the connections for leaks.

  6. Mix half liquid detergent and half water in a bucket and check for gas leaks. Place the connected joint into a bucket containing the liquid and watch for bubbles when the gas is turned on. If bubbles are present, tighten the connection or apply more tape until no bubbles rise from the connection.

  7. Plug electric dryers directly into the power socket. Check that the socket is capable of the voltage necessary for the dryer as many electric dryers require 240 volts. If your power outlet is only 120, call an electrician for help.

  8. Connect the metal ducting pipe between the dryer and the external dryer vent, securing the ducting pipe with metal ducting tape. Unlike regular duct tape, metal ducting tape is non-flammable. Clamp the ducting to the vent and the source pipe in the dryer, tightening the clamp around the ducting by screwing it shut.

  9. Push the connected units into final position. Turn on the circuit breaker to use your newly installed washer and dryer.

Warning

  • Never vent the dryer into attics or crawl spaces, as this can lead to mold growth.
