What to Do When Water Bursts from Behind Your Washing Machine
Immediate steps to stop the flooding, protect your home, and get emergency plumbing help fast.
August 7, 2026
What should I do if water is suddenly shooting out from behind my washing machine? If water is spraying across your laundry room, take a deep breath and act immediately. This almost always means a supply hose has burst or come loose under full water pressure. Because these supply lines are connected directly to your plumbing system, water will continue to pump out at full force until the supply is cut off. Here are the exact steps you need to take right now to stop the flow, protect your home, and stay safe.
Step 1: Shut Off the Water Right Now
Your top priority is stopping the source of the water. Do not try to hold the hose, tape it, or wipe up water while the lines are still active. You need to shut off the water supply immediately.
- Check the dedicated laundry valves: Look directly behind or above your washing machine in the recessed wall box. You will typically see two valves—one for hot water (red) and one for cold water (blue). Turn both valves completely clockwise (or flip the single lever shut if you have a ball-valve shutoff).
- Use the main water shutoff if needed: If the dedicated valves are stuck, corroded, leaking, or impossible to reach behind a heavy machine spraying water, do not waste time. Head straight to your home's main water shutoff valve (often located in a basement, crawlspace, utility room, or near the water meter) and turn off the water to the entire house.
Step 2: Cut Power Safely
Water and electricity create a dangerous combination. Once the water flow is stopped—or while someone else in the house is turning off the water—you must address the electrical supply to the washer.
If you can reach the power cord safely without stepping into standing water or touching wet appliances, unplug the washing machine from the wall outlet. If there is water pooling near the outlet, or if the cord is submerged, do not touch it. Instead, go directly to your electrical breaker panel and switch off the breaker labeled for the laundry room or washing machine.
Step 3: Contain the Water to Limit Damage
Once the water is off and the electrical hazard is eliminated, start clearing the water as fast as possible. Standing water can soak through flooring, penetrate baseboards, and seep into subflooring in a matter of minutes.
- Lay down heavy bath towels, blankets, or moving pads to soak up the bulk of the standing water.
- If you have a wet/dry shop vacuum, use it to quickly extract water from hard floors or carpet.
- Move laundry baskets, rugs, and nearby items out of the room so they do not trap moisture against the floor.
- Open windows and turn on portable fans or dehumidifiers to get air circulating immediately.
Why a Burst Supply Line Cannot Wait
A burst washing machine hose is not an issue that can sit until a routine service appointment later in the week. A standard residential supply line can release hundreds of gallons of water in under an hour. Even after you turn off the main valve, your home is left without running water until the damaged lines and connection points are repaired or replaced.
Furthermore, standard rubber hoses that burst often indicate aging hardware, high water pressure, or failing shutoff valves in the laundry box. If the shutoff valve itself broke or failed to close completely during the incident, the entire fixture requires prompt professional attention before water can safely be restored to your household.
