1. Confirm the Leak and Power Off

Before diving into detailed troubleshooting, confirm whether you are dealing with an active dishwasher leak or a simple liquid spill:

• Confirm the leak: Clean up the surrounding water and monitor whether moisture returns during a test cycle. If water does not reappear, it was likely an external spill.
• Safety first: If you see visible water leaking underneath or if an LC/LE error code appears, immediately turn off the power to the dishwasher at your home's circuit breaker before inspecting internal components.

2. Inspect Water Supply & Drain Hoses

Inspect the main water lines and connection points for loose fittings, cracks, or damage:

• Water Supply Hose: Inspect where the hose connects to both the dishwasher and your home's valve. Ensure fittings are tight. If damaged, replace it with a 3/8-inch stainless steel braided hose.
• Drain Hose Connection: Ensure the drain hose is tightly secured to the sink siphon or disposal. If newly installed with a garbage disposal, verify that the knockout disposal plug/cap was removed.

3. Check Door Rubber Gasket and Detergent Type

Door seal gaps and excessive soap suds are common culprits for leaks around the front door panel:

1. Align and clean the door seal: Inspect the rubber seal along the perimeter of the tub. Push any misaligned sections back into the channel, and clean off debris using a soft cloth with mild soap.
2. Use dishwasher-specific detergent: Never use liquid dishwashing hand soap. Dish soap generates high amounts of foam and suds that break the door seal pressure, forcing water out onto your floor.

4. Leveling, Nozzles, and Cabinet Screws
