Show stop conditions
- Water is near an outlet or junction box
- The leak continues with power off
- Panel removal is required to locate the source
Likely causes
- The door seal or lower door area is dirty or damaged
- Hand dish soap or excess detergent is creating foam
- A supply or drain connection is loose
- The dishwasher is overfilling or not level
- A pump, sump, diverter, or internal hose is leaking
Quick checks, in order
Stop the cycle and disconnect power
Close the water supply if leakage continues.
Remove foam safely
If hand dish soap was used, stop the machine and follow manufacturer guidance. Do not add random chemicals.
Inspect visible connections
Check the supply line, drain hose, and door perimeter without removing panels.
Confirm the appliance is level
A forward tilt can direct water toward the door.
When does the leak begin?
Focus on the supply connection, inlet path, float, and overfill condition.
Door sealing, foam, spray deflection, pump, or sump leaks are more likely.
Check the drain hose, sink connection, pump area, and backflow.
Close the water valve; the supply line or inlet valve may be leaking.
Stop and get qualified help when
- Water is near an outlet or junction box
- The leak continues with power off
- Panel removal is required to locate the source
Frequently asked questions
Can the wrong soap make a dishwasher leak?
Yes. Hand dishwashing liquid creates excessive foam that can escape through the door and vents.
Is a wet door edge always a bad seal?
Not necessarily. Loading, spray-arm obstruction, foam, or leveling can direct water toward an otherwise usable seal.
