Possible Causes
How to Fix / Troubleshooting
Safety: Disconnect power and turn off water supply immediately to prevent further leakage.
- Check inside the tub: Look for excessive suds (from non-dishwasher detergent) that can cause overfilling. If present, run a rinse cycle without detergent after power is restored.
- Inspect door gasket: Examine the rubber gasket around the door for tears, gaps, or debris preventing a good seal. Clean and reseat as needed.
- Remove toe kick and inspect base: Look under the dishwasher for standing water in the base pan. If water is present, dry it thoroughly with towels or a wet/dry vacuum.
- Identify leak source: While observing (with power restored briefly), run a short fill and watch hoses, the sump, and the pump connections for drips.
Repair or replace any leaking component (door gasket, hose, sump, or pump seal). Do not continue using the dishwasher until the leak is corrected, as it can damage flooring and electrical components.
