Possible Causes

Loose hose clamp, Cracked dishwasher inlet nipple, Damaged dishwasher drain hose, Knockout plug fragments obstructing seal

How to Fix / Troubleshooting

Safety first: Turn off power to the disposal and dishwasher.

  • Check clamp: Tighten the hose clamp securing the dishwasher drain hose to the Whirlpool disposal inlet.
  • Inspect hose and nipple: Look for cracks in the plastic inlet or splits in the hose. Replace the hose or disposal if the nipple is broken.
  • Verify knockout removal: Ensure the knockout plug was fully removed and no fragments remain that could prevent a tight seal.
  • Test for leaks: Run the dishwasher drain cycle or pour water into the dishwasher and observe the connection for drips.
