How to Repair a Leaking Washing Machine
While noticing a water leak coming from your washing machine is likely to take little effort, identifying the cause of the leak and making the washing machine repair may be a bit more time-consuming and involved. Do not avoid the repair simply to avoid the potential headache of the repair, as leaving the leak could result in permanent damage to the washing machine, nearby appliances like the dryer and the floor and wall space in your laundry room.
Determine the leak's origin. Dry the wet areas around the machine and watch for signs that water is reappearing. Likely places to find a leak include the hot and cold inlet hoses located on the back or top of the machine and the drain line, which is located on the rear, lower portion of the machine.
Turn off the water supply for the leaking inlet hose if you determine the leak originates there. Unscrew the leaking hose and replace it with a new supply hose if the leak is located within the length of the old hose. If the leak comes from one end of the hose, keep the old hose but wrap plumber's tape clockwise around the threaded part of the connection. Replace the washer in the non-threaded part of the connection if it appears particularly worn. Retighten the connection, dry the hose and turn the water back on. Watch for more water to appear to ensure the leak is fixed.
Run a cycle on the washing machine if you cannot determine the leak's origin. Watch the drain line as the washer drains, and identify which portion of the line leaks. You may need to use an inspection mirror to attain a line of sight to the drain hose. Reinsert and tighten the retaining screws that hold the drain hose to the machine if the leak originates at the connection to the machine. If the leak is within the length of the hose, replace it with a new one.
Unplug the machine if the leak doesn't appear to originate in any of the places you've previously inspected. Remove the front of the washing machine by inserting a painter's scraper and prying the spring snaps up, remove the back by taking out screws and the rear plate, or tip the empty machine so you can view the inner workings from beneath.
Look for a rubber hose coming down from the tub to a small electric drain pump. A plastic line will leave the pump and go to the back of the machine, where it will meet up with the drain line you inspected previously. With your inspection mirror and flashlight, look for water to indicate a leak. These lines are often held on by metal springs and can be moved or adjusted with open-jaw pliers. If you find one of these hoses damaged, take it off and take it with you to your appliance store for a replacement.
