If the washer is leaking water the drain pump might have a hole or crack. Or, the bearings might be worn out. Replace the drain pump if it is leaking water, they're not repairable.
Tub to Pump Hose
If the washer is leaking water the hose from the tub to the pump might be split or torn. Don't try to cut off the bad piece of hose and stretch it to fit the pump, this will put strain on the remainder of the hose and may cause a sudden and complete failure of the hose which will dump potentially hundreds or thousands of gallons of water onto the floor because the next time the washer tries to fill all of the water will end up on the floor and so the washer will never shut off the valve. Any time there is a damaged hose, replace it completely with the OEM part.
If the washer is leaking water check the drain hose. The most common places for the hose to spring a leak is from the connection to the pump out to the back of the washer. Another common occurrence is when the washer gets pushed too far back against the wall.
