Hex wrench won't fit the garbage disposal reset hole

Symptoms

• 1/4-inch hex wrench doesn't fit into the bottom center hole
• No visible hex-shaped hole on the bottom of the unit
• Unit has a different unjamming mechanism, like a wrenchette tool
• You're using a wrench from a different brand's disposal

Likely causes

• CommonWrong size wrench for this modelMost residential disposals use a 1/4-inch hex wrench, but always confirm against the manual.
• CommonModel uses a self-service wrenchette or different jam-clearing methodSome brands use a small included tool that isn't a standard hex wrench.
• PossibleDebris or paint blocking the holeA hole that's there but clogged with buildup can seem like it doesn't fit.
• PossibleUnit has no bottom access hole at allSome models rely only on the upper flywheel access via a broom handle method.

What to do

1. Check your disposal's brand and model number, often on a label on the side of the unit.
2. Look up the specific jam-clearing method for that model, since not all use the same hex hole size or tool.
3. Clean out the bottom center hole with a small tool or toothpick if it looks like it's blocked by debris.
4. If your model has no bottom hole, use the alternate method: insert a broom handle into the top opening against one of the impeller vanes and push to rotate the flywheel.
5. Always disconnect power before attempting either method.
6. If neither method works and the flywheel still won't turn, treat it as a deeper jam or mechanical failure needing professional help.

Tools and parts

• Correct-size hex wrench for your model
• Broom handle (alternate method)
• Flashlight

When to call a pro

If you can't identify the right jam-clearing method for your model or it still won't budge, a plumber or appliance tech can service it safely.
