Dishwasher leaks water onto the floor from underneath the cabinet, not from the door.

Safety first: Disconnect power and shut off water immediately to prevent damage.

• 1. Remove toe-kick panel: Inspect the area under the dishwasher with a flashlight for signs of dripping or dried mineral trails.
• 2. Run a short cycle: With the panel off, run a quick wash and observe where water begins to leak (fill, wash, or drain stage).
• 3. Tighten clamps: If you see drips at hose connections, tighten the clamps or replace them if corroded.
• 4. Inspect sump and pumps: Look for cracks in the plastic sump, circulation pump housing, or drain pump. Replace any leaking components with Insignia-compatible parts.
• 5. Check base pan: If water accumulates in the base pan, dry it thoroughly and confirm the leak source before reassembling.

Because underbody leaks can worsen and cause electrical hazards, consider professional service if you cannot clearly identify and fix the source.
