Coffee Grinder Jammed With Beans? Causes and How to Fix It

Beans stuck in the chute and the grinder straining to move them? A bean jam is one of the most common grinder problems, usually caused by oily roasts or a stray object, and it clears in a few minutes.

Here is why beans jam and how to clear them.

This article will teach you:

• Why beans jam a grinder
• How oil and debris contribute
• How to clear the jam
• How to prevent it

Why the Beans Jam

• Oily dark-roast beans sticking together.
• A stone or stem among the beans.
• A grind set very fine choking the burrs.
• An overfilled hopper.

What You’ll Need

• A brush and vacuum
• Grinder cleaning tablets
• Your owner’s manual

How to Clear a Bean Jam

1. Unplug it. Always unplug before reaching near the burrs.
2. Empty the hopper. Remove beans and check for stones or debris.
3. Clear the chute. Brush and vacuum grounds packed in the burrs and chute.
4. Adjust the grind. Coarsen slightly if a fine setting keeps jamming.

Pro Tip: Buy beans from a source that screens out debris, since a single small stone can jam and even chip burrs. If you grind oily roasts, clean more often to prevent sticky clogs.

When to Look a Little Deeper

Because jams stall the mechanism, it helps to check related parts, and reviewing a grinder that will not spin, a stuck burr, or a stuck motor can reveal the cause.

When to Call a Pro

The jam itself is DIY. If clearing it reveals chipped burrs or a motor that no longer turns, those parts need replacing.

Wrapping Up

Bean jams are usually oil or debris. Here’s the recap:

• Unplug before clearing.
• Empty the hopper and check for stones.
• Brush out the chute and burrs.
• Coarsen the grind if needed.

Clear the chute, and grinding resumes. You’ve got this.

The last step is the part itself: match a coffee maker parts to your model number rather than to a photo or a part name.
