Possible Causes

Worn or torn door gasket, deformed lower door seal, spray arm hitting door and forcing water at seal, over-sudsing from wrong detergent

How to Fix / Troubleshooting

Safety First: Turn off power and avoid running the dishwasher until the leak is fixed.

Inspect door gasket:

  • Open the door and examine the rubber gasket around the tub opening for tears, gaps, or flattening, especially at the bottom corners.
  • Clean the gasket and mating surfaces with warm soapy water to remove grease and debris.

Check lower spray arm:

  • Ensure the lower spray arm is not cracked or warped and does not strike the door when spun by hand.

Replace seals if needed:

  • If the gasket is damaged or hardened, replace it with a KitchenAid-specific door gasket.
  • If water appears to leak from the very bottom center, the lower door seal (behind the inner door panel) may need replacement.

Detergent check:

  • Use only dishwasher detergent; if regular dish soap was used, run several rinse cycles to clear excess suds.
