Replacing a washing machine drain hose is easier than it sounds. The drain hose on your washing machine may become worn or cracked after several years of use. The rubber may begin to wear down, since the dirty water is forced through the hose under high pressure. Replacing the hose only takes a few minutes using a screwdriver and a pair of pliers. Buy a new hose, install it yourself and save up to $100 by not having a repairman come to your house.
Write down the model and serial numbers of your appliance, as well as the brand name. These are printed on a steel plate bolted to the back of the washer. Take this information to the parts store so you can buy the right replacement hose for your machine.
Unplug the washing machine's power cord.
Lift the old drain hose straight out of the drain pipe and lower it into a bucket to allow any residual water to empty out of the hose without making a mess.
Remove the old hose by unscrewing the clamp that attaches it to the back of the washer. Use a screwdriver to remove the clamp while holding the hose close to the clamp with a pair of pliers to prevent it from rotating while you work.
Check the clamp. If it is in good shape and not damaged by rust, you can reuse it.
Slip the clamp over the straight end of the new hose and slide it up the hose about 1 inch.
Fit the hose over the metal connector on the back of the machine and slide the clamp over the hose where it seats on the connector.
Tighten the clamp securely and wiggle the hose to be sure it won't accidentally pop off the washer.
Slide the washing machine back into position in your laundry room, insert the drain hose into the drain pipe and reconnect the power, making sure your hands are dry.
