Dishwasher leaking

Water appears in front of the door, under the unit, or inside the sink cabinet.

Start hereStop the cycle and shut off the water valve if the leak continues.

Narrow it down

What this symptom can tell you

Water comes from the front of the door

Excess suds, a blocked spray pattern, an item in the seal, or an unlevel installation may be involved.

Water appears under the sink

A supply line, drain hose, disposal connection, faucet, or sink plumbing may be the source.

Water appears beneath the machine

An internal hose, pump, seal, or inlet component may be leaking and normally requires service.

These patterns narrow the next check; they do not confirm a failed part. Use the exact model number and any displayed code before ordering parts or authorizing repair.

Try these checks in order

Exact controls and access points differ by model. Stop when a step does not match your appliance or manual.

  1. 1

    Find the leak timing

    Dry the area and observe from a safe distance. Note whether leaking starts during filling, washing, or draining.

    What you want: The timing narrows the likely path.
  2. 2

    Clear the door seal

    Remove food, labels, or utensils from the visible gasket and door edge. Do not remove the seal.

    What you want: The door closes evenly against a clean gasket.
  3. 3

    Correct loading

    Large trays or handles can deflect spray toward the door. Reposition items and ensure racks are fully seated.

    What you want: Nothing touches the door or blocks spray arms.
  4. 4

    Use dishwasher detergent only

    Hand dish soap and too much detergent create foam that can escape the door.

    What you want: The detergent type and amount match the manual.
  5. 5

    Check under-sink connections

    Inspect the water and drain connections for drips or a loose hose. Do not disturb hard-wired connections.

    What you want: Visible plumbing connections stay dry.

Most common categories

Possible causes to consider

  • Hand dish soap, too much detergent, or detergent not intended for automatic dishwashers.
  • A dish or utensil directing spray toward the door.
  • Debris or damage visible on the door seal.
  • A loose, split, or leaking visible hose or plumbing connection.
  • An internal pump, tub, seal, or valve leak requiring service.

Stop and arrange help when

  • Water is near wiring, an outlet, or the control panel.
  • A hose or tub is split or spraying.
  • The door, hinge, or latch is damaged.
  • The leak comes from underneath the cabinet.

If the problem remains

Find the full model number. Open the official manual, check for a recall, and describe which checks you completed before contacting service.

Common questions

Dishwasher leaking: FAQs

Can dish soap cause a dishwasher leak?

Yes. Hand dish soap creates excessive foam that can escape around the door and base. Stop the cycle and follow the manufacturer’s suds-removal guidance.

Why does the dishwasher leak only on some loads?

A tall utensil, cutting board, pan, or overloaded rack may redirect spray or prevent the door from sealing consistently.

Can I keep using a dishwasher with a small leak?

No. Stop using it until the source is identified. Even a small leak can reach flooring, cabinetry, wiring, or nearby outlets.
