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.

Answer these first

01

Does the water appear at the front edge of the door, or from underneath the kick plate?

02

Does it show up while the machine fills, while it washes, or while it drains?

03

Is there suds or foam on the floor, or only clear water?

04

Was a different detergent used recently, or regular dish soap by mistake?

05

Is the floor damp even when the dishwasher has not run for a day?

Dishwasher leaking water: 5 checks, and none of them costs anything.

01

Shut the dishwasher off and wipe the floor dry so you can see where fresh water comes from.

02

Confirm the detergent is made for automatic dishwashers and that the dose was not doubled.

03

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
  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Questions about
dishwasher leaking water.

It only leaks a little at the front. Can I keep running it?
Not for long. A small drip at the door usually means water is also reaching places you cannot see, such as the underside of the cabinet floor or the insulation around the tub. Put a towel down, run it only when you are home, and book a visit before the particleboard starts to swell.
Could the leak be coming from the sink instead?
Yes, and it is worth ruling out. The dishwasher drain often joins the sink drain or a garbage disposal under the same cabinet, and a leak at that joint drips down beside the dishwasher. Open the sink cabinet and look for wet pipes or a damp cabinet floor.
Why is there foam on the floor?
Foam means the wrong soap or too much of it. Liquid hand dish soap is the usual culprit. Scoop out what you can, add a tablespoon of vegetable oil to the tub to knock the suds down, and run a rinse cycle with no detergent.
Will a new door gasket fix it?
Only if the gasket is the source. Many leaks that look like door leaks come from a machine that sits out of level or from a seal at the bottom of the door that is separate from the main gasket. Checking level and watching where the first drop appears is worth doing before buying a seal.
