InSinkErator Jam-Buster Wrench - 08305D

InSinkErator Jam-Buster Wrench - 08305D

Free simple garbage-disposal jams with this InSinkErator Jam-Buster Wrench - 08305D. This disposer service wrench fits the center hex opening on compatible InSinkErator-manufactured disposers so the motor shaft can be worked back and forth from underneath the unit.

08305D is a manufacturer accessory for InSinkErator disposers, not a universal plumbing wrench. It is used when the disposer hums, stalls, or is blocked by a simple jam and the reset button alone does not restore operation.

Compatibility: Works only with InSinkErator-manufactured garbage disposers that have the matching center service hole in the bottom of the disposer.

Fitment / What To Verify: Confirm the disposer is an InSinkErator model and that the bottom of the disposer has the center hex service opening before ordering. Do not force this wrench into non-matching disposal openings or use it as a general-purpose hex key.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Disposer hums but does not turn, flywheel is jammed, blades or impellers will not move freely, or the disposer trips the reset after a blockage.
• Visible/Sensory Cues: Foreign object jam, stalled turntable, humming motor, tripped overload button, or resistance when rotating the bottom service opening.

Pro Tip: Always turn power off before clearing a jam. Work the wrench back and forth, remove the obstruction from above with tongs, then press the reset button only after the turntable moves freely.
