Disposal runs but grinds slowly or leaves chunks
A running motor with poor grinding points to a partial jam, impellers (lugs) stuck in place, packed buildup around the grind ring, too little water flow, or worn grind components. On older units a worn grind ring often means replacing the disposal.
Before you start
- Turn the disposal off at the switch and breaker (or unplug) before looking or reaching in.
- Never put a hand in the hopper; use tongs.
