Washer Leaking From the Bottom? Where the Water Points You

A washer leaking from the bottom can come from a loose hose, a dirty pump filter, too many suds or a house drain backing up. Note where the water appears and when in the cycle, since that narrows the cause. Samsung says leaks almost always have easily remedied causes. Damage inside the cabinet is a technician job.

A washing machine leaking on the floor is one of several symptoms in our washer troubleshooting guide.

Make the floor safe before you look

Whirlpool’s own first steps are to turn the washer off at the controls, unplug the cord and check that the wall valves are off.

Where the washer leak appears

The spot where the water collects is your best clue, so start with the matching row.

Inlet hoses and faucet connections

Inlet hoses and their fittings are the first thing to check behind the washer. Samsung says to inspect every hose and connection at both ends, including the rubber and the o-rings, and to replace anything damaged.

LG says hoses may need tightening and that the rubber seal in each fitting must be in place and not torn. With the faucets off and a bucket handy, LG says to refit the hose without cross-threading it. A faucet leaking at the pipe or around its valve is a job for a plumber, according to LG.

Whirlpool says water dripping into the washer while it is off may point to the inlet valve on the back of the machine. Replacing a valve is a technician job unless you are experienced and the washer is unplugged.

Drain hose and the house standpipe

A clogged house drain often looks like a washer fault. LG says a restricted standpipe makes water overflow onto the floor, and that this “may be perceived as a washer leak.” To test it, pour a pitcher of water quickly into the standpipe. If it overflows, LG says to contact a plumber.

If the standpipe clears, look at the hose itself. Samsung says the drain hose should go in at least 6 inches and no more than 8. Under 6, it may fall out and spill water on the floor. Over 8, it can siphon. A zip tie holds it in place, and the connection must not be airtight.

Samsung says damaged hoses should be replaced, and its drain hose steps say to request service for a damaged one. LG also sends a damaged top-load drain hose to repair service, so check with your maker before you swap one yourself. See why a washer won’t drain for each maker’s height limits.

Door seal, detergent drawer and suds

A door seal can leak over something very small. Samsung says to fold the seal back and look, since even a single strand of hair or thread can cause a leak. A damaged seal means requesting service on Samsung’s page, and LG says the same of a torn gasket.

Detergent is the next suspect. Samsung says too much detergent or non-HE detergent, even once, can bring excess suds, residue, leaks or leak errors. To clear it, run an empty cycle with no detergent and repeat until no suds remain. Our SUd page covers the Samsung code for this.

LG adds two more causes on top-load washers: bleach dispenser residue can overflow and leak from underneath, and high home water pressure may overfill the trays. For the second, LG says to turn down the water valves and run another cycle.

Pump filter caps on front-load washers

Pump filters on most Samsung front-load washers sit near the bottom on the front. Samsung says a neglected filter can clog and lead to draining issues and even leaks, and asks for a clean at least monthly or every 40 washes, whichever is more frequent.

After a cleaning, LG says to make sure the residual hose and filter caps are securely closed.

Overloading and an unlevel washer

Load size and leveling matter on both washer types. LG says top lid leaks can come from an overloaded tub, and that clothes should stay below the top level of the holes in the drum. Whirlpool says an unlevel washer may leak from the door seal.

Leak codes on the display

Some washers report a leak themselves. LG front-load washers can show AE, listed with the rest on the LG washer code list. Samsung uses LE, LC, 1E and 1C for moisture or water level sensor faults, explained on the Samsung washer code list.

Test run, and when to request service

A short test shows whether your fix worked. Samsung suggests a cycle such as Rinse & Spin and says to request service if the leak continues.

Whirlpool says a cracked or loose drain pipe near the pump, or a faulty tub seal, is inside the machine and may need a professional technician. Have your model number ready. If the drum stops turning once the leak is fixed, see washer won’t spin.
