Possible Causes

Loose dishwasher hose clamp, Cracked dishwasher inlet nipple on disposal, Deteriorated dishwasher hose

How to Fix / Troubleshooting

Safety First: Turn OFF power to the disposal and dishwasher. Avoid running either appliance until the leak is fixed.

Step-by-step:

  • 1. Inspect the connection: Locate the dishwasher drain hose where it attaches to the KitchenAid disposal's side inlet. Look for drips while running water or the dishwasher.
  • 2. Tighten clamp: Use a screwdriver or nut driver to tighten the hose clamp. If a spring clamp is used, reposition it closer to the nipple ridge.
  • 3. Check hose condition: Flex the hose near the connection. If it is cracked, brittle, or swollen, replace the hose with a new dishwasher drain hose of the same diameter.
  • 4. Inspect inlet nipple: If the plastic or metal nipple on the disposal body is cracked, the disposal housing is compromised.
  • 5. Test for leaks: Run the dishwasher through a drain cycle and observe the connection for any seepage.

When to call a technician: A cracked inlet nipple requires replacement of the disposal; a technician can handle both plumbing and electrical reconnection.
