How to Change a Leaking Water Supply Hose on a Washing Machine

Updated February 21, 2017

A leaking water-supply hose on a washing machine doesn't just waste water, it also presents a hazard. Washers are powered by electricity. A leaking hose in the vicinity of an electrical socket presents the potential for disaster. It's not difficult to change a leaking water-supply hose on a washing machine. The sooner the problem is remedied, the safer you and your family will be.

Turn off the electricity for the washing machine. Unplug the machine if it is safe to do so. Otherwise, turn off the power at the main circuit. Cut the power at the circuit box if the machine has leaked water all over the floor, as it will help prevent accidental electrical shock.

Turn off the water supply for the leaking supply hose. The water supply for washing machines is usually mounted on the wall or floor behind the machine. There are two valves, one for the hot and one for the cold water supply. Turn the knobs to the right until they stop. You may need to move the washing machine out of the way to reach the hose. Have an assistant to help you as needed.

Clean up the area with the mop and a bucket. Wipe up excess water with a towel.

Unscrew the coupling on the end of the water supply hose next to the water supply valve. Use a pair of pliers as needed to help you get the coupling loose. Unscrew the other end of the hose from the washing machine.

Wrap both the water supply valve threads and the threads on the washing machine with plumber's tape. Attach the couplings on either end of the new hose to the water supply valve and washing machine inlet. Tighten with the pliers.

Restore the power to the washing machine. Turn the water supply valves back on by turning the handles counterclockwise.

Run a short load in the washer. Watch the hose for leaks. When everything is working properly, move the washer back to its original location.


Replace your old hoses with braided hoses. These are more expensive, but much more durable than standard washer hoses.


Always use great care when working around water and electricity.
