My Washing Machine Flooded My House. What Should I Do?
Shut off the water first, then document the damage. Sudden appliance leaks are usually covered, but slow, known leaks often aren't.

Why the washing machine matters more than the water
A washing machine hose that bursts is sudden and accidental, and that's the phrase your policy is looking for. The water came from a specific failure, at a specific time, and you couldn't have stopped it. That's usually covered under the same part of your policy that handles a burst pipe, which pays to repair the floor, walls and cabinets the water reached, and your dwelling coverage declarations page shows that limit. What it won't pay for is the washing machine itself breaking down, that falls under a home warranty or the manufacturer, not homeowners insurance. If this is the second time this machine has leaked, or you noticed it dripping weeks ago, the insurer may call it a maintenance problem instead of a sudden one, and that distinction decides the claim.
See What Rebuilding Actually Costs You
Water damage claims hinge on policy limits and how insurers read 'sudden' versus 'neglected.' Comparing coverage now shows whether another policy handles this kind of claim differently, before you need it again.
What about the floor underneath, and will this cause mold
If the water sat for more than a day or two before you found it, there's a decent chance it's reached the subfloor. That changes the scope of the claim. Insurance adjusters look at how long the water was present as part of deciding whether this was sudden or something that built up over time. A washing machine hose that blows out and floods the kitchen in an afternoon is a different claim than water that seeped under the flooring for a week while you were away. Get the water up and the area drying as fast as you can, with fans or a dehumidifier if you have one. Take photos before and during that process so there's a record of when you found it and what you did.
Mold is where a lot of these claims get complicated. Most policies cover mold that results directly from a covered water loss, like the sudden leak itself, but they often cap how much they'll pay for mold remediation separately from the rest of the water damage, sometimes a few thousand dollars regardless of the dwelling limit. Some policies exclude mold outright unless it's a direct and immediate result of a covered peril. Your policy's mold provision, if it has one, is usually its own section, not folded into the general water damage language, so it's worth finding that page specifically rather than assuming the dwelling limit covers it.
Acting fast matters beyond just limiting damage. An insurer reviewing a claim where mold has already set in will ask when the leak happened and when it was addressed. If there's a gap of several days or more between the leak and the cleanup, that gap becomes part of the story the insurer tells about whether this was sudden damage or a neglected one that grew into a bigger problem. Drying the area, pulling up wet flooring if needed, and getting a water mitigation company involved quickly all work in your favor. Keeping receipts for that work supports the claim even if some of it turns out not to be reimbursed.
If the washing machine is on an upper floor, check whether water reached the ceiling or walls of the room below, since that's often where the more expensive damage actually is. A claim that looks like a kitchen floor repair can turn into a ceiling and drywall repair downstairs, and that affects both the total cost and which parts of your coverage apply. Walk the rooms below and around the laundry area, not just where the machine sits, before deciding how bad the damage is.
Sewer backup, drains, and why that's a separate coverage
Everything said so far about sudden and accidental damage applies to clean water coming from inside an appliance or a pipe. Water that backs up through a drain or a sewer line is handled differently, and it catches people off guard because it feels like the same kind of problem. A standard homeowners policy typically excludes sewer and drain backup entirely unless you added an endorsement for it, often called sewer backup or water backup coverage, bought as a separate rider with its own limit, usually lower than your dwelling limit. If your washing machine's drain line backed up instead of the supply hose bursting, check for that endorsement specifically, because the general water damage language in your policy likely doesn't reach it.
The reason insurers split this out is that backup is often tied to something outside the house, a municipal line, tree roots, or a clog that built up over time, and that shifts it closer to a maintenance or infrastructure problem than a sudden accident inside your walls. If you don't have the endorsement and this turns out to be a backup rather than a straightforward appliance failure, the claim may be denied even though the water damage looks identical to what a burst hose would cause. It's worth asking whoever inspects the damage to say plainly which type of event this was. That determination is what the rest of the claim depends on.
Flood is a separate question again, and it's easy to conflate with either of the above. If the water came from outside, rising groundwater, a storm, a river, that's flood damage, and it's excluded from every standard homeowners policy regardless of how the water entered the house. Flood coverage is its own policy, usually through the National Flood Insurance Program or a private flood insurer, and it has to be purchased ahead of time. A washing machine leak isn't a flood claim, but if heavy rain around the same time also pushed water in through a foundation crack or window well, that portion of the damage falls outside homeowners coverage entirely and needs to be sorted out separately from the appliance claim.
Before filing, take a few minutes to figure out which of three things actually happened. It could be a sudden internal failure, a backup from a drain or sewer line, or water that came from outside the house. Each one points to a different part of your policy, or to no coverage at all. Knowing which one you're dealing with before you call in the claim saves a round of back and forth with the adjuster later.
Before you file
Pull your declarations page and find the dwelling coverage limit, the mold provision, and whether sewer or water backup was added as an endorsement. That tells you what this claim can actually pay for.
