Who pays when my dishwasher leaks into the unit below?

It depends on your HOA's governing documents (CC&Rs and bylaws), your unit owner's policy and the association's master policy. In many associations the owner is responsible for appliances inside the unit and damage they cause, but the rules vary. Read your documents and contact your insurer and HOA manager promptly.

Can I keep using a dishwasher that leaks a little?

No. Small leaks under a dishwasher often go unnoticed for weeks and can soak the subfloor and cabinets. In a condo, the water may also reach the ceiling of the unit below. Turn off the supply valve until the source is found and fixed.

Should I install a water leak sensor under my dishwasher?

It is a good, low-cost step, especially in multi-story buildings. A battery-powered sensor on the floor beside or under the dishwasher can alert you to water early. Some systems also include an automatic shutoff valve.

Why does my dishwasher leak only with certain detergent?

Using regular dish soap or too much detergent can create excess suds that push out past the door seal. Use only automatic dishwasher detergent in the recommended amount, and rinse dishes that were washed with hand soap before loading them.

Dishwasher Leaks in Condos: Find It Fast, Limit Damage

In a single-family house, a dishwasher leak usually means a wet kitchen floor. In a condo or apartment, the same leak can soak the subfloor, run along a joist and show up as a stain on the ceiling below you. Many Las Vegas condo complexes, from the Strip corridor through Paradise and Spring Valley, stack kitchens directly on top of each other, so a small leak can spread to units you never see. This guide covers what to do in the first few minutes, how to find the source and how to prevent the next one.

First 10 Minutes: Stop the Water

Stop the cycle. Cancel the cycle and let the dishwasher drain if it can.
Shut off the water. The supply valve is usually under the kitchen sink, on the hot water line, often with a braided line running toward the dishwasher. Turn it clockwise until it stops. If you cannot find it or it will not close, use the main shutoff for your unit.
Cut the power. Unplug the dishwasher under the sink, or switch off its breaker if it is hardwired. Do not stand in water while you do this; turn off the breaker at the panel first if the floor around the outlet is wet.
Dry everything you can reach. Use towels on the floor, and pull out the bottom kick plate to see how far the water spread.
Tell your neighbor below. Ask them to check their kitchen ceiling and cabinets. Spotting a stain early is far better than finding mold later.

Where the Water Is Coming From

Where the water appears tells you a lot about where it starts.

Water at the front of the door

Door gasket. The rubber seal around the tub opening can tear, flatten or come out of its channel. Food debris stuck on the gasket also breaks the seal.
Excess suds. Hand dish soap or too much detergent produces foam that pushes past the seal.
Uneven install. A dishwasher that tilts forward or sideways can let water run out under the door.
Door hinges or springs. A door that does not close tightly cannot seal.

Water underneath, toward the middle or back

Water inlet valve. The fitting where the supply line connects can loosen or crack, or the valve body can leak. Hard water makes scaling and seal wear more likely on these valves.
Drain hose. Check the clamp at the sink drain or disposer and the hose itself for splits.
Pump and sump seals. The circulation pump and the sump at the bottom of the tub have seals that wear with age.
Cracked tub or spray arm housing. Less common, but a cracked tub floor leaks on every cycle.

Water coming out of the air gap or the sink

If your sink has a countertop air gap (a small cap near the faucet) and water spits from it, the drain line between the air gap and the disposer or drain is clogged. A disposer that was recently installed with its knockout plug still in place causes the same problem.

Water on every cycle, from all around

An overfill problem, such as a stuck float or a failed float switch or inlet valve that will not close, can raise the water level high enough to leak at several points. Many dishwashers have a float under a small dome in the tub floor; make sure it moves freely.

Safe Checks You Can Do

With the water and power off:

Inspect and clean the door gasket with warm water. Look for tears and gaps.
Remove and clean the filter in the bottom of the tub. A clogged filter can cause water to back up.
Check that the float moves up and down freely.
With a flashlight, look behind the kick plate at the supply line connection and drain hose for drips or white mineral trails, which show an old, slow leak.
Check that the dishwasher is level and secured to the counter or cabinet sides with its mounting brackets.

Do not run test cycles with the kick plate off and hands near the wiring. If you need to watch where water appears, have a technician do it with the right precautions.

The Condo and HOA Side

Every association is different, so treat this as a checklist, not legal advice:

Read your CC&Rs and bylaws. They usually say who is responsible for appliances, plumbing inside walls and damage to neighboring units.
Notify the HOA or property manager if water may have reached common elements or another unit. Some associations require prompt notice.
Contact your insurance company. Unit owners often carry an HO-6 policy; renters carry renters insurance. Take photos of the leak, the damage and the source.
Keep records of the repair: what failed, which part was replaced and when.
Renters should tell their landlord or manager right away. Landlords usually arrange the repair.

Some buildings also limit when contractors can work or require advance notice, so ask your manager when you book a repair.

Preventing the Next Leak

Replace an old supply line with a braided stainless line, and replace a sticky or corroded shutoff valve.
Add a water sensor on the floor near the dishwasher, or a sensor with an automatic shutoff.
Don't run the dishwasher while you're away or asleep in a multi-story building.
Manage hard water. Southern Nevada water is very hard, around 16 to 18 grains per gallon. Use a rinse aid, keep the dishwasher's water-softener salt filled if your model has one, and run a dishwasher cleaner periodically to limit scale on valves and seals.
Look under the sink every few months for drips.

Repair or Replace After a Leak?

Gaskets, hoses, inlet valves, float switches and pump seals are common, reasonable repairs. A cracked tub, a corroded base or a leak that has already rusted the frame on an older machine are usually the point at which replacement makes more sense. Water damage to the cabinet or subfloor is a separate repair that may need a contractor, and it is worth documenting before the dishwasher is reinstalled.
