Kitchen appliance leaks are sneaky. A refrigerator ice maker line or a dishwasher connection can drip for weeks under the cabinets before anything shows. Then one day the hardwood in front of the dishwasher is cupped, a toe kick is swollen, or there's a stain on the basement ceiling under the kitchen. Other times it's sudden: a line lets go and there's water across the floor.
Either way, here's how to handle it.
Stop the Water Safely
Don't touch anything electrical if water is near it. Refrigerators and dishwashers plug in behind or under cabinets, close to the water. Don't reach for the plug or the outlet. Call an electrician or us first.
Dishwasher: the supply valve is usually under the kitchen sink. Turn it clockwise if you can reach it from a dry spot.
Refrigerator: the ice maker and water dispenser line often has a small valve under the sink or in the basement ceiling below the kitchen. If you can't find it, use the main shutoff.
Don't drag the refrigerator out across wet hardwood. Softened boards dent and gouge easily, and the line behind it may still be connected.
Common Sources
Refrigerator supply line. The thin line feeding the ice maker and dispenser can crack, kink or loosen at the connection, especially after the fridge has been moved.
Water filter housing inside or behind the refrigerator.
Dishwasher supply connection under the machine, behind the lower panel.
Dishwasher drain hose under the sink, or a door gasket that lets water out during a cycle. Water from the drain side has been through the wash, so don't handle it, and mention it when you call.
Appliance repair or a plumber fixes the source. Our job is the water damage it left behind.
Where the Water Hides
Kitchen leaks spread under things, not across them. Check:
The floor in front of the appliance. Cupped or darkened hardwood, lifted tile edges, or vinyl that's bubbling.
Toe kicks and cabinet bottoms. Swollen or peeling toe kicks and soft cabinet floors under the sink.
The ceiling below. If your kitchen sits over a basement, look for stains or drips there.
Next to the appliance. Water travels under cabinets and can show up a few feet away.
Take photos of all of it before anything is moved.

Mission Hills Kitchens: Older Homes, Original Materials
Many Mission Hills homes date from the 1920s through the 1940s. Plumbing in homes that age has usually been updated in stages, so a kitchen may have newer appliance lines connected to older pipes, all hidden in the same wall or cabinet. Original hardwood, plaster ceilings and millwork are common, and they're worth saving.
That shapes how we work. Plaster ceilings under a kitchen can often be dried in place, and when a cavity needs air, small, well-placed openings are easier to patch than a large cutout. Original hardwood can often be dried where it is. We take readings first and treat removal as the last option.
How We Dry a Kitchen Leak
Map the water. Moisture meters on the floor, cabinets, walls and the ceiling below show how far it went.
Get under the cabinets. We can often dry under cabinets by removing toe kicks or drilling small holes in hidden spots, without pulling the cabinets out. If readings show that won't work, we explain the options first.
Dry the hardwood in place when readings support it, using a floor-mat drying system: panels taped to the floor and connected by hoses that pull moisture out of the wood.
Run dehumidifiers and air movers and take readings during the job until materials are dry.
Document everything with photos and readings for your insurance company.
On a recent kitchen job in Overland Park, water got under the hardwood in and around the kitchen, and the boards were wet and badly cupped. We set up a floor-mat drying system with dehumidifiers running alongside, and the floor was dried in place, with readings tracked throughout.
Our appliance leak page has more on dishwasher and refrigerator leaks, and our guide to whether wet hardwood can be saved goes deeper on floors.
Insurance and Slow Kitchen Leaks
Coverage depends on your policy and on how long the leak went on, and your insurer decides. Many policies treat sudden leaks differently from slow ones. Keep the failed part if you can, note when you found the water, and take photos. We document what we find, including signs of how long materials were wet.
Frequently Asked Questions
Do the dishwasher or refrigerator need to be pulled out?
Sometimes, so we can dry and check the floor underneath. The appliance should be disconnected by a plumber or appliance tech first. We will tell you if it's needed.
Can my kitchen cabinets be saved?
Often. Many cabinets can be dried in place by opening the toe kick or drilling small holes in hidden spots. Cabinet bottoms made of particleboard that have swollen usually need repair or replacement.
Can original hardwood in an older home be dried?
Often, if drying starts soon. We check moisture in the boards and the subfloor and dry in place when readings support it. How well boards recover depends on how long they were wet.
Who fixes the appliance?
An appliance repair tech or plumber repairs or replaces the line or the appliance. We handle drying the floor, cabinets, walls and ceiling.
