Your washing machine fills up with water to wet down your clothes and dissolve the detergent. The clothes flow around the agitator, which helps clean the load. Water then empties out of the washing machine during the spin cycle. If your top-loading washing machine has a leak, see if you can locate the cause of the leak. Fixing the problem yourself saves you money on repair fees.
The most common reason for water beneath the washing machine is the drain and fill hoses. These hoses connect to the back of the washing machine near the bottom of it. See if the connections are loose, and tighten them. Verify that the fill hose washers are correctly installed. Clean the hoses if clogged. See if your home drain or plumbing is backed up. Clean the plumbing yourself, or contact a licensed plumber to assist you. Examine the hoses for punctures or cracks. Replace the hoses if necessary.
The pump is in the main housing of the washing machine. It helps move water out of the top-loading washing machine during the spin cycle. It has hoses that run through it. See if the hoses are punctured. Check the pump housing for cracks. If the hoses or pump are compromised, replace the entire pump. You usually can't repair individual pump components.
See if the drum casing has cracked. If so, this causes leaks at the bottom of your washing machine. You must replace the outer tub. This is a difficult and costly repair; consider purchasing a new washing machine. Check the main tub seal and the o-ring near the base of the agitator. If these components crack or tear, your washing machine will leak. Unplug the washing machine, and remove the old seals if necessary.
Your washing machine will leak if the washing machine is not level. Adjust the leveling legs, or fix the floor beneath the washer. Redistribute the load if the washer is unbalanced. Don't overload the washing machine since water can bounce off of the load onto the floor. Check the door seal. If the seal is cracked, torn or falling off, replace it. Clean the air gap if it's clogged. See if the water inlet valve or the tube that runs through is leaking. If the tube is leaking, just replace the tube. You must get a new water inlet valve if the valve itself is leaking. Change out the inlet spout if it is warped or cracked.
