How do I fix a jammed coffee grinder?
To fix a jammed coffee grinder, first unplug the device for safety. Clear any visible debris from the hopper and burr chamber using a stiff brush or vacuum. If the jam persists, adjust the grind setting to a coarser position to release trapped beans, or disassemble the burrs according to your manual to remove the obstruction.

A jammed grinder is a common frustration, but it is usually easy to resolve with a bit of patience. The most frequent cause of a jam is a foreign object—like a small stone or a piece of wood—that has made its way into the hopper along with the coffee beans. These hard objects can get wedged between the burrs, causing the motor to stall or the grinder to stop completely.
Before you do anything, safety is paramount. Always unplug the grinder before attempting to clear a jam. Never reach into the burr chamber with your fingers while the machine is plugged in. Once the power is disconnected, start by emptying the hopper. Use a vacuum or a stiff brush to remove any loose beans or grounds that might be obscuring the problem.
If the jam is caused by a buildup of coffee grounds rather than a foreign object, you might be able to clear it by simply adjusting the grind setting to its coarsest position. This opens up the gap between the burrs, which can allow the obstruction to fall through. If this doesn't work, you will need to disassemble the grinder. Consult your owner's manual for the specific steps to remove the top burr. Most home grinders are designed to be disassembled for cleaning, and this is often the only way to reach a stubborn jam.
Once you have access to the burrs, use a brush to clear away the compacted coffee. If you find a stone or other debris, remove it carefully. While you have the grinder apart, it is a great time to give the burrs a thorough cleaning. Use a dry brush to remove any oils or old grounds that have accumulated over time. Avoid using water, as this can cause rust and damage the motor.
In practice, prevention is the best cure. Always inspect your beans before pouring them into the hopper, especially if you are buying from a source that doesn't use rigorous sorting. If you find that your grinder jams frequently even with clean beans, it may be a sign that your burrs are dull or that the motor is struggling. Regular maintenance and cleaning will keep your grinder running smoothly and help you avoid these mid-morning emergencies.
