Stop the water and power first
Standing water under a dishwasher reaches cabinets, subfloor and the wiring junction box behind the kick plate. Turn off power at the breaker, close the hot-water supply valve under the sink, and keep the machine off until the source is found. Water that keeps coming after the valve is closed is a plumbing issue, not the dishwasher.
What it
usually means.
A dishwasher only holds a gallon or two in its sump at a time, so a leak that soaks the floor is usually not one big failure but water escaping at a specific joint. The door edge, the lower corners, the supply connection and the drain connection under the tub each leak in a recognizable way. Where the puddle forms, and at which point in the cycle, tells a technician most of what they need before the kick plate comes off.
The 6 causes, cheapest first
Answer these first
Does the water appear at the front edge of the door, or from underneath the kick plate?
Does it show up while the machine fills, while it washes, or while it drains?
Is there suds or foam on the floor, or only clear water?
Was a different detergent used recently, or regular dish soap by mistake?
Is the floor damp even when the dishwasher has not run for a day?

before you book.
Dishwasher leaking water: 5 checks, and none of them costs anything.
Shut the dishwasher off and wipe the floor dry so you can see where fresh water comes from.
Confirm the detergent is made for automatic dishwashers and that the dose was not doubled.
Remove the kick plate and look with a flashlight for drips at the supply line and the drain hose.
Also worth checking
- Run a finger along the door gasket, especially at the lower corners, for tears or flattened spots.
- Place a level across the tub opening; the front should not sit lower than the back.
The causes,
cheapest first.
6 things dishwasher leaking water turns out to be, from wrong detergent or too much of it to cracked tub or sump housing.
The cost guide-
01 no repair
Wrong detergent or too much of it
Hand dish soap or an overdose of gel makes foam that pushes past the door seal. The fix is running an empty rinse cycle, not a part.
-
02 lowest
Machine not level
A tub tilted toward the door sends water against the lower edge of the seal instead of back to the sump. Adjusting the front legs often ends it.
-
03 low
Worn or shifted door gasket
The rubber seal around the tub opening flattens and hardens with heat over the years, and a gap at the lower corners lets spray reach the floor.
-
04 low
Loose or cracked supply connection
The fitting where the hot line meets the inlet valve sits under the tub. A slow drip here wets the floor even between cycles.
-
05 low to moderate
Leaking drain hose or pump seal
Water that appears only during the drain portion usually comes from a split hose, a loose clamp or a pump whose shaft seal has worn.
-
06 moderate to highest
Cracked tub or sump housing
A crack in the tub floor or sump leaks on every cycle regardless of detergent. On an older machine this is where replacing the unit becomes a fair question.
