Appliance Leak
Washing machines, dishwashers, water heaters, and refrigerators with ice makers are common sources of appliance-related leaks. Shutting off the water supply to the appliance, if safe to reach, is usually the first step.
Where to check
Most major appliances have a dedicated shut-off valve. Checking the supply line, connection fittings, and drain hose can help identify an obvious source, though some leaks (such as an internal water heater tank failure) may not have a simple fix.
Why flooring is often affected first
Appliance leaks often go unnoticed for a period of time since they can occur behind or underneath the unit, which means flooring and adjacent cabinetry are frequently affected before the leak becomes obvious.

Frequently Asked Questions
Which appliances most often cause water damage?
Washing machines, dishwashers, water heaters, and refrigerators with ice makers are common sources, since each has a supply line, fittings, or a drain hose that can fail.
Where is the shut-off valve for my appliance?
Most major appliances have a dedicated shut-off valve on the wall or supply line behind or beneath the unit. Washing machines typically have separate hot and cold valves; turning both off stops additional water even when the exact failure point is unclear.
Why is appliance leak damage often worse than it looks?
Appliance leaks frequently occur behind or underneath the unit, so they can continue unnoticed for some time. Flooring, subflooring, and adjacent cabinetry are often already affected by the time the leak becomes visible.
