Laundry and kitchen appliances live next to receptacles on purpose. When a hose lets go, the water does not respect that plan. Standing on a wet floor and unplugging a dishwasher is how people get hurt. The sequence is breaker or shutoff first, then towels.
If water is at a range or dryer outlet, treat it with the same seriousness as a laundry leak. Those circuits are not gentle.
What to shut off
Know the breaker for the dishwasher, washer, and refrigerator. Know the water valves under the sink and behind the washer. If you cannot reach the appliance valve because of the flood, the house shutoff is the next move.
Do not mop and probe
Do not reach into a dishwasher kickplate or a washer pump while the machine might still be live. Do not use a shop-vac on standing water around an outlet unless the circuit is off. Phones as flashlights still involve a person kneeling in water.
After the floor is dry
A one-time drip from a loose dishwasher supply that you tightened is worth watching. Recurring leaks, rust at a receptacle, or a breaker that tripped during the flood are visit-worthy. Say where the water went — toe kick, outlet, neighbor’s ceiling — because that changes whether the appliance or the house needs attention first.
