A leaking hose on a washing machine is an easy thing to change, although sometimes simply replacing the hose washer, or gasket, is all that is needed. It is a good idea to turn off the water valve at the back of the machine whenever you are away to prevent flooding the room should the hose burst while you are gone.
Purchase a new high pressure washing machine hose from your nearby home improvement store.
Pull the washing machine out from the wall so that you can reach the shutoff valve located behind the washer. Turn off the water supply to the hot and cold supply pipes at the valve.
Disconnect the faulty hose at the valve. Turn the connector to the left or counterclockwise, gripping it with a pair of pliers or a wrench to loosen and disconnect the hose. Lift the hose to drain the water from it. Repeat the process, disconnecting the hose at the back of the machine.
Screw the new water supply hose onto the connection at the back of the washer. Hand-tighten the fitting by turning it to the right or clockwise
Connect and tighten the hose to the water supply valve on the wall. If you are replacing both hoses, be sure you connect the hot water hose to the hot water fitting and the cold to the cold fitting.
Turn on the water valves and check the hoses and connections for leaks. If you notice a leak, tighten the fittings again. Make sure the drain hose is in place on the drain and push the washer back into place along the wall.
Check the level of the machine and adjust the feet if necessary. Turning the foot to the left raises the machine and to the right lowers it.
Old or worn valves benefit from a layer of PTFE thread seal tape wrapped around the valve fitting before screwing the hose on.
