How to replace the drain hose on an automatic washing machine

Updated February 21, 2017

A rubber washing machine drain hose may be prey to dry rot and erosion from the wash water it expels. Alarming puddles in the laundry area could indicate leakage from a worn washer drain hose. Cracks and wear in the rubber signify the need for a new hose. Most homeowners elect to save the cost of a service call by making the replacement, not a full-scale plumbing operation by any means, themselves.

Unplug the washing machine and pull it at least 8 inches away from the wall. That will make room to access the drain hose clamp with the necessary tool.

Loosen the clamp holding the washer drain hose from the nozzle in back of the machine. The clamp will either have a screwdriver slot for adjusting the tension, or it will be a pressure ring with two tabs on one end and another tab within an inch of them. Loosen a screw clamp with counterclockwise turns of a slotted screwdriver until it freely slides up or down the hose. Loosen a pressure clamp by pinching the tabs with adjustable pliers and squeezing the single tab toward the two tabs. Push the ring clamp up or down the hose to release it from the nozzle and free the hose.

Pull the hose off the nozzle on back of the washing machine. Pull the other end out of the standpipe drain or utility sink it uses for drainage.

Slide the clamp over the end of the new washer drain hose that connects to the machine. Slip that end onto the washer nozzle. Slide a screw clamp over the part of the hose that covers the nozzle and tighten with a slotted screwdriver. Grip the tabs on a pressure clamp and push it in place over the hose portion covering the nozzle.

Push the other end of the drain hose into the standpipe or drainage sink. Push the washing machine back against the wall and run a small load to test the new drain hose for leakage.


Drain hoses for washers are shaped with a hook to fit into the standpipe, and variations to the design accommodate the location of the washer drain nozzle. Remove the old hose and bring it to the hardware store to find a replacement with the same shape.
