Once the flow has stopped, dry the area and trace the source: hose couplings, the drain hose and standpipe, the door boot or too many suds. By [WasherRepair.center technical team](https://washerrepair.center/authors/technical-team/) Published September 25, 2026 ## At a glance. The first few minutes after you find water around a washer decide how far it spreads and whether anyone gets a shock. Power and water come first; finding the source can wait until the floor is safe to stand on. Read the whole guide ### First move Stop the cycle, then cut the power At the breaker panel if the water has reached the outlet, the plug or the cord. ### Second move Close both supply valves Hot and cold, on the wall behind the washer or in a recessed wall box. ### Fill hoses Inspect monthly, replace every five years Speed Queen's schedule, even for hoses that still look sound. ### House drain 17 gallons a minute or more Whirlpool: a slower standpipe or sink backs up and passes for a washer leak.

Questions ## Power first, then the water Most washers plug into an outlet low on the wall behind the cabinet, which is exactly where spreading water collects. If the puddle has reached the outlet, the cord or a power strip, do not reach behind the machine or stand in the water to unplug it. Go to the breaker panel and switch off the circuit that feeds the laundry room, then come back. If the floor around the outlet is dry, press pause or cancel, wait for the drum to stop and pull the plug by its body rather than the cord. Only then close the supply valves, the pair of handles where the hoses leave the wall. A leak that stops the moment the valves close came from the supply side; one that keeps dribbling came from water already inside the tub or the drain. ### If water is still pouring out A split fill hose releases water at full household pressure until something closes it, and it does not stop when the washer does. If the valves behind the machine cannot be reached, will not turn or are themselves leaking, close the main shutoff for the house, usually near the water meter or where the supply enters a basement or garage wall. ### If the washer stopped with the tub full A front-loader that stops mid-cycle keeps its door locked and its water behind the glass. Leave it there for now. Draining it through the pump filter puts more water on a floor you are trying to dry, and it can wait until towels, a shallow tray and a dry place to kneel are ready. ## Where the water is tells you where it came from With a washer leaking water on the floor, look at the shape of the wet area and where it is deepest before you mop. Water runs toward the low side of a floor, so the source is usually on the high edge of the puddle, not in its middle. - Behind the washer, below the valves: a hose coupling, a missing rubber washer or a cracked hose. - Running down the wall under the standpipe: the house drain is backing up or the drain hose popped out. - In front, under the door of a front-loader: the door boot, a dirty glass edge or too many suds. - Out from under the middle of the cabinet: something inside, such as the pump, an internal hose or the tub seal. - Near a laundry sink: the sink drain, its faucet or the hose hooked over its rim. ### When in the cycle it happens Water that appears while the washer fills points to the supply side: hoses, couplings or the inlet valve. Water that appears during the pump-out, in bursts, points to the drain hose, the standpipe or the pump. A leak only during a fast spin on a front-loader often comes from the door boot or from suds forced past it. Close on a hand turning a washer's cold-water supply valve to off, the hose attached below. ## The fill hoses and their couplings Each fill hose has a flat rubber washer inside both ends, and a coupling without one weeps no matter how hard it is tightened. Overtightening or cross-threading does the opposite kind of damage, cracking a plastic valve port or deforming the seal. Speed Queen's instructions call for couplings screwed on finger-tight and then turned about a quarter turn more with pliers. Rubber hoses age from the inside, under constant pressure and hot water. Speed Queen asks owners to look at them every month for cracks, blisters or worn spots, to replace any hose that shows one right away, and to replace all fill hoses every five years regardless. LG tells buyers to install new inlet hoses with a new washer rather than reuse the old pair. ### Why automatic flood-stop hoses are not the easy fix Hoses with a built-in shutoff are meant to close when the flow jumps, as it would after a burst. LG and Speed Queen both advise against them, because a modern washer's fast fill can trip the device and leave the machine unable to fill. A floor sensor beside the washer, or closing the valves when you are away, protects the room without that side effect.

Whirlpool's help pages say the standpipe or laundry sink must carry away at least 17 gallons of water a minute; a partly clogged drain line cannot keep up, and the water rises out of the top of the pipe. It looks like the washer is leaking, but the machine is doing its job and the house drain is not. Clearing a clog in the house line beyond the standpipe is plumbing work, not appliance work. These signs point to the drain rather than the washer: - Water marks running down the wall under the standpipe. - A gurgle from a nearby sink or floor drain while the washer pumps out. - A laundry sink that empties slowly even when the washer is off. - Water that appears only in bursts, at the moments the pump runs.

Speed Queen's leak checklist names oversudsing and oversized loads alongside the hoses, and Whirlpool adds thickened no-splash chlorine bleach, which can foam up in the same way. On a front-loader, also check the folded rubber boot around the door opening for tears or holes, and wipe the outer edge of the door glass where the seal presses against it. A hair, a thread of lint or a film of detergent there is enough to let water creep out during the spin.

A leak from the valve body, inside the wall or from the house drain beyond the standpipe belongs to a plumber. If water reached the outlet or the cord, leave that circuit off until an electrician has looked at it.

Four steps, in the order worth doing them. 01 ### Stop it and make it safe Cancel the cycle. If water has reached the outlet or cord, switch the laundry circuit off at the panel instead of unplugging the washer by hand. 02 ### Close the water Turn both supply valves off. If they cannot be closed, use the main house shutoff. 03 ### Dry and look Soak up the water, note where it was deepest and check the hose ends, the standpipe and the door boot with a flashlight. 04 ### Test the supply side alone With the washer still unplugged, open the valves and watch both hose couplings for several minutes. Drips there mean a washer or a hose, not the machine. For the heart of your home. ## Questions owners ask. ### Can I run one more load to see where the water comes from? Not with water already on the floor. Dry the area first, test the hose couplings with the washer unplugged, and if nothing shows, run a short rinse while you watch, ready to stop it. ### The leak stopped after I mopped. Is it safe to ignore? No. An intermittent leak usually returns during the same part of the cycle, and a hose that has started to weep can split. Find which part of the cycle it happened in before the next load. ### The washer stood in water for a while. Can I plug it back in? LG's manual says not to touch a washer that has been sitting in standing water and to get instructions before using it again. Wiring and the motor near the floor may be wet, so have it checked first. ## The problems behind it. Each has a page of its own: what it usually means and the causes in the order worth checking.

The repairs on the right are where this guide ends when the checks do not settle it. ### Drain pump repair Water left in the drum and clothes that come out soaked, traced to the pump filter, the pump, or the hose and standpipe behind it. ### Door boot and odor repair A musty smell, black spots in the rubber seal or a drip at the bottom of the door, repaired at the boot, the dispenser and the drain path. ### Bearing and tub seal repair A roar on the spin that grows louder over weeks, rust streaks under the tub or a drum that wobbles on its shaft, traced to the bearing and its seal. ### Water inlet valve repair A washer that will not fill, fills slowly, fills with only cold water or keeps filling, repaired at the inlet valve and its screens. ## More in water and electrical safety.
