Main Drain Hose

• When the machine leaks while emptying and/or during the spin cycle, the main drain hose could be the source of the leak. The main drain hose is a fat hose connected behind the machine. Inspect the hose thoroughly to see if there are holes or tears. Water may be visible on the hose and you can run your hand along the hose to feel for water. Contact a repairperson to have the hose replaced. If you feel skilled and confident, you can attempt to replace the hose yourself. Review your manual for directions.
  
  

Inlet Hoses

• The inlet hoses are smaller hoses also on the back side of the machine. One hose connects to your hot water supply and the other connects to your cold water supply. Check both for leaks and notice the floor area below the hoses. If the leak has been going on for a while, there could be a build up of water on the floor. It’s wise to replace both hoses at the same time, even if only one hose is leaking to balance the integrity of your water supply hoses. This is a similar principle to replacing two tires instead of only one on a car. You should also consider upgrading to stainless steel hoses if you’ve been using rubber hoses, as they are more durable.
  
  

Water Pump

• The water pump is designed to remove water from the machine’s tub. In some cases, it leaks because it’s clogged and overloaded so it drains water when it’s emptying. To confirm that this is the problem, you will need to check the pump unit. You’ll need to take off the front panel or the entire cabinet for the washer, depending on how your machine is constructed, and refer to your manual to find out where the pump is located. Kenmore and Whirlpool models typically have the pump attached to the motor drive on the bottom of the machine. If the leak is coming from the pump, schedule a repairperson to come by and notify them about your findings.
  
  

Outer Tub

• Another component to troubleshoot if the hoses and pump seem fine is the outer tub inside of the washer. Your washer has two tubs -- an inner tub and an outer tub made of steel or plastic. Inspect as much as you can view for signs of rust, splits or punctures. If you find anything of this nature, your outer tub may need to be replaced. This might be a tough call, because replacing an outer tub can be costly as it’s a main component of your machine. If your washing machine is old, it might be time to retire your washer and get a new one.
