Press the button and hear nothing, or just a hum with no grinding? A coffee grinder that will not spin is usually jammed or waiting on a safety lock, and both are quick to check.
Here is why a grinder stops spinning and how to fix it.
This article will teach you:
- Why the grinder will not turn
- How safety locks work
- What to check first
- When the motor has failed
Why the Grinder Won’t Spin
- Beans or grounds jamming the burrs or blade.
- A safety lock if the hopper or lid is not seated.
- A tripped thermal cutoff after overuse.
- A failed motor or switch.
What You’ll Need
- A brush and vacuum
- Your owner’s manual
How to Fix a Grinder That Won’t Spin
- Unplug it. Always unplug before clearing near blades or burrs.
- Seat the parts. Make sure the hopper and lid click into place to satisfy the safety lock.
- Clear a jam. Remove beans and brush out grounds binding the burrs.
- Let it cool. If it ran hot, wait for the thermal cutoff to reset.
Pro Tip: Many grinders will not start unless the hopper and lid are locked in exactly right. Reseat them with a small twist before assuming the motor is dead.
When to Look a Little Deeper
Because a stalled grinder ties to jams and the motor, it helps to check those, and reviewing a stuck motor, jammed beans, or a stuck button can pinpoint the cause.
When to Call a Pro
If the grinder is clear, seated, and cool but still will not spin, the motor or switch has failed. For most home grinders, replacement is the practical choice.
Wrapping Up
A grinder that will not spin is usually a jam or lock. Here’s the recap:
- Unplug before clearing.
- Seat the hopper and lid.
- Clear jammed beans.
- Let a hot motor cool and reset.
Check the lock and jam first, and it often spins again. You’ve got this.
