Kraus garbage disposal makes a rattling noise only when the dishwasher is draining.

Safety First: Turn OFF power to both appliances before inspecting connections.

• Step 1 – Inspect dishwasher inlet: Check the dishwasher hose connection at the disposal for looseness or vibration.
• Step 2 – Secure hose: Tighten the hose clamp and support the hose so it does not vibrate against the cabinet or disposal.
• Step 3 – Clean inlet: Remove the hose and check for debris at the inlet. Clean as needed.
• Step 4 – Test dishwasher drain: Run a drain cycle and listen. Mild water noise is normal; loud rattling may indicate loose internal parts, in which case replacement of the disposal may be needed.
