Appliance Leak Water Damage: Washers, Dishwashers, Fridges and AC Units

Appliance leak water damage spreads fastest where you cannot see it, under flooring, behind cabinets and into the ceiling below. Close the appliance's shutoff valve (or the main water valve), turn off its breaker if the outlet or cord is wet, and pull nothing out of a puddle while it is still plugged in. State Farm says a failed washing machine hose can release an average of 650 gallons an hour. One free call connects you with an independent local restoration company, 24/7.

The next 10 minutes

1. Stop the water. Washers have hot and cold valves on the wall behind them. Dishwashers and fridge icemakers usually have a valve under the kitchen sink. If you cannot find it, shut the main.
2. Cut power safely. If the plug or outlet is in water, switch off the breaker instead of touching the cord.
3. For an AC leak, turn the system off at the thermostat so it stops making condensate.
4. Move rugs, boxes and anything stored near the appliance.
5. Check the room below. Upstairs laundry rooms and kitchens leak into ceilings.
6. Photograph the hose, connection or drain pan that failed, and the wet area, then call.

Common appliance leaks and what they mean

Washing machine

Supply hoses burst or crack, and drain hoses slip out of the standpipe. Supply water is clean, drain water is gray. The laundry floor, the walls behind it and the room below take the hit.

Dishwasher

Door gaskets, supply lines, drain hoses and pumps fail. The water is usually gray, and it runs under the cabinets and toe kicks where it soaks the subfloor without showing.

Refrigerator

Icemaker and dispenser lines split or come loose, or the drain pan overflows. The water is clean, but it spreads under the fridge, under cabinets and into the floor below.

Air conditioner

A clogged condensate line or cracked drain pan drips slowly from an air handler in the attic or a closet. Small amounts over weeks end up as ceiling stains and wet closet walls.

Drain water from washers and dishwashers carries detergent and food or soil, so restoration crews usually treat it as Category 2 (gray) water under the ANSI/IICRC S500 standard. Clean supply-line water can turn into a mold problem within a couple of days if it sits in a wall or under a floor.

What the crew does on arrival

• Confirm the source is off and the appliance is unplugged or isolated.
• Moisture mapping with meters and thermal imaging. Kitchen and laundry leaks hide under vinyl plank, laminate, tile and cabinet bases, so readings decide what has to come up.
• Extraction of standing water and wet carpet in nearby rooms.
• Targeted removal: toe kicks, baseboards and sometimes the lower cabinet back or a strip of flooring, so dry air can reach the subfloor. Cabinets can often stay in place.
• Drying with air movers, dehumidifiers and sometimes injection systems that blow dry air under cabinets or into wall cavities.
• Monitoring on return visits until the subfloor and framing read dry, with logs for the insurer.

What appliance leak water damage costs

Kitchens cost more than laundry rooms because cabinets, countertops and flooring are more expensive to remove and replace. A quick response is what keeps cabinets in place. Use the water damage cost calculator for your square footage.

The insurance side

The Insurance Information Institute lists "accidental discharge or overflow of water or steam" from a household appliance as covered under HO-2 and higher policies. That usually covers the floors, walls and cabinets damaged by a sudden hose failure. The broken appliance itself is generally not covered, and policies exclude damage from lack of maintenance, so a dishwasher that has dripped for months is harder to claim than a hose that burst this morning.

Keep the failed hose or part. Our water damage insurance claim tips cover what to photograph and save.

How long it takes

Extraction and setup usually happen on the first visit. Drying under cabinets and flooring commonly takes several days, and longer for hardwood or tile over plywood. EPA notes that materials dried within 24 to 48 hours usually do not grow mold, which is why waiting until next week to deal with a damp kitchen floor is a mistake.

What you can safely do while you wait

• Mop and towel up surface water.
• Pull the bottom drawer or kick plate on the sink cabinet to let air in, if it comes off easily.
• Open cabinet doors near the leak.
• Do not run the leaking appliance again until it is repaired.
• When you replace hoses, consider steel braided ones and, as the Insurance Information Institute suggests, a water leak monitoring and shut-off system.

When it becomes dangerous

• Water has reached outlets, cords or a power strip behind the appliance.
• A gas dryer or gas range is standing in water.
• The ceiling below a laundry room or kitchen is sagging. See ceiling water damage repair.
• A musty smell suggests the leak has been going on unseen. Our page on signs of hidden water damage lists what to look for.

What to ask on the phone

• Can you dry under the cabinets without removing them?
• Will you check the floor below and the walls behind the appliance?
• Are your technicians IICRC certified?
• Do you treat dishwasher or washer drain water as gray water, and what does that change?
• Do you work with my insurer and provide moisture logs?
• Is there an emergency fee, and is flooring replacement included or separate?

The call is free and there is no obligation to hire. If the water heater is the appliance that failed, the water heater leak cleanup page covers the extra safety steps for gas and hot water.
