Garbage disposals

Garbage disposal jam won't clear even with the hex wrench

If the hex wrench won't turn the flywheel at all, the jam may be more severe than usual, or the object is positioned somewhere the wrench can't effectively reach.

Symptoms

  • Hex wrench is fully inserted but won't rotate the flywheel at all
  • Significant resistance or it feels completely locked
  • No visible object from a flashlight check
  • Broom handle method also fails to move it

Likely causes

  • CommonObject wedged very tightly between the impeller and grind ringSome objects lodge at an angle that resists rotation in either direction.
  • PossibleMultiple objects or debris compounding the jamMore than one piece of debris can lock the mechanism more firmly than a single item.
  • PossibleMechanical failure unrelated to a jam, such as a seized bearingIf nothing is visibly stuck, the flywheel itself may have seized from corrosion or bearing failure.

What to do

  1. Confirm power is off and unplugged before continuing to work on it.
  2. Try turning the wrench firmly in both directions rather than just one, since some jams only release one way.
  3. Try the alternate method: insert a broom handle into the top opening against an impeller vane and apply steady pressure to rock it.
  4. Use a flashlight and, if possible, a small mirror to look at multiple angles inside the chamber for anything missed.
  5. If you can see an object but can't reach it safely, use long needle-nose pliers rather than forcing the wrench harder.
  6. If nothing is visible and the flywheel truly won't budge at all, treat it as a likely mechanical seizure rather than a simple jam.

Tools and parts

  • 1/4-inch hex wrench
  • Broom handle
  • Flashlight
  • Long needle-nose pliers

When to call a pro

If the flywheel remains completely locked after trying both unjamming methods, a plumber or appliance tech can safely disassemble the unit or advise replacement.

Safety

Use caution

Don't force the wrench with excessive strength, and never substitute your hand for a tool inside the chamber.
