How to Fix a Leaky Washing Machine Faucet That Won't Cut Off

The two faucets in your laundry room or basement deliver hot and cold water through a pair of hoses connected to your washing machine.

When you disconnect the hoses, perhaps to repair or replace the washing machine, you may notice that one or both of the faucets leak water. Over time, the rubber washers inside a faucet begin to wear, warp and crack, causing leaks. The washers may even start to disintegrate from years of exposure to water. Stopping the leak requires a faucet repair kit available at plumbing and hardware stores.

Step 1

Unplug the washing machine's power cord before working on the faucet and pipes.

Step 2

Twist the knob of each faucet clockwise as far as it will turn.

Step 3

Unscrew the hoses from the two faucets, using the adjustable wrench.

Step 4

Tighten the top knob of each faucet again to see if this will stop the leak. If not, continue troubleshooting.

Step 5

Close the main water valve in your home. The valve is usually in a basement or crawlspace along an exterior wall but may be near the water heater or street.

Step 6

Twist the large nut at the end of the faucet counterclockwise with an adjustable wrench to remove the faucet.

Step 7

Pull out the packed washers inside the faucet below the threads. Place the washers on a countertop or other flat surface in the precise order you remove them from the faucet. If the washers are visibly damaged or cracked, or if the rubber smears on your fingertips, it's time to replace the washers.

Step 8

Clean the interior threads of the faucet with an old cloth. Wipe down the threads on the wall water pipe as well. A good cleaning helps the faucet seal tight against leaks. If the threads have caked-on debris, use a wire brush to clean.

Step 9

Press the new washers from your repair kit into the faucet in the reverse order that you removed the old washers. Match each new washer to the size of the old one before installing in the faucet.

Step 10

Apply plumber's tape in overlapping layers around the wall pipe threads.

Step 11

Attach the repaired faucet to the threaded pipe and tighten clockwise with the wrench.

Step 12

Open the main valve to restore water flow in the home.

Step 13

Tighten the facuet nut with the wrench to eliminate any small leaks.

Step 14

Reconnect the washing machine hoses and plug in the electrical cord after drying your hands. Check all connections for leaks.
