Grease hardens inside pipes, trapping debris and narrowing flow.
Foreign Objects
Utensils, plastic, twist ties, and small objects can block water flow.
Drain Line Blockage
The disposal may be clear, but the drain line beyond the trap could be clogged.
Quick Checks You Can Try Safely

Run cold water for 30 seconds before and after operating the disposal to help flush debris.
Use a Sink Plunger
A standard sink plunger can help dislodge blockages.
Baking Soda & Vinegar Flush
