Electric washing machines were introduced to the U.S. mass market in the early 1900s. They've grown by leaps and bounds since then, but the basic principles of a washer have stayed the same: Clothes are washed in the tub and spun by an agitator. The dirty water is then pumped out of the machine and into your home's sewer system through a drain hose. When installing a new washer, connecting this washing machine drain hose is your final task.
Unplug the washing machine or turn off the power to the circuit where the machine is installed at the main switch. Position yourself at the rear of the washing machine. This may require you to move the machine out from the wall if that is where it is placed. Have an assistant help you if you have a heavy machine.
Connect the drain hose to the washing machine. There are two main ways to do this, depending on your machine. The first is to insert the hose into the drain outlet on the washing machine and then twist it in by hand to lock in place. The second is by inserting the hose in the drain outlet and then tightening the coupling by hand to secure. Follow the proper procedure for your washer model.
Secure the other end of the drain hose to the sewer inlet. The majority of drain hoses have a goose neck-type outlet that holds it securely in the sewer drain. For added stability, wrap a plastic cable tie around the goose neck and the sewer inlet and tighten it in place. A bit of wire works for this as well.
Return the washer to its original location. Restore power to the washer.
Run an empty load in the washer on the shortest setting. Observe the hose as the drain cycle starts and ensure there are no leaks.
