Possible Causes

Loose debris intermittently jamming impellers, Warped turntable, Damaged grinding ring segments, Worn motor bearings causing rotor misalignment

How to Fix / Troubleshooting

Safety first: Turn OFF power before attempting to clear debris.

  • Step 1 – Clear chamber thoroughly: Use tongs and a flashlight to remove all visible debris. Rotate the impellers with a wooden spoon to expose hidden items.
  • Step 2 – Manual rotation: Use the jam-buster wrench to rotate the shaft several full turns, feeling for any binding.
  • Step 3 – Test with light load: Run the disposal with only water and a small amount of soft food. If it still seizes intermittently, internal components are likely damaged.
  • Step 4 – Replace unit: Warped turntables or damaged grinding rings are not user-serviceable. Replace the disposal.
