What Causes Grinder Not Working?

KitchenAid coffee makers feature programmable timers and thermal carafes.

Maintenance neglect: Irregular descaling and cleaning are the top causes.
Component wear: Seals, gaskets, and pumps degrade with use.
Water quality: Hard water causes scale that blocks sensors and heating elements.
Model-specific issues: Kitchenaid grinder not working has known patterns in KCM111, KCM120, KCM140.

Step-by-Step Fix

Follow these steps specifically for Kitchenaid machines:

Remove all beans from the Kitchenaid hopper. Clean the burrs with a dry brush.
Check the chute for blockage. On Kitchenaid machines, oily beans can clog the funnel.
Listen for motor hum. If humming, manually rotate the burrs to dislodge the jam.
Inspect the grinder gear. Kitchenaid machines use plastic gears that strip under load.

Frequently Asked Questions

Why is the grinder on my KitchenAid machine not working?

A silent grinder is usually a jammed burr set, a tripped safety switch, or a worn drive gear. A KitchenAid grinder that stops usually has beans jammed in the burrs, an empty-hopper sensor triggered, or worn burrs. Empty and brush the hopper, run a few dry beans through, and never force the motor. Detailed steps in our Grinder Not Working guide.

My KitchenAid Kcm150 grinder stopped — how to fix it?

When the grinder on a KitchenAid stalls, the first suspects are jammed beans and the hopper sensor. Clear the burrs with a brush, refill the hopper, and run a short grind. If it still stops, the burrs or drive gear may be worn — see our Grinder Not Working guide.

How do I unjam the grinder on a KitchenAid coffee machine?

A silent KitchenAid grinder is most often a jam or a tripped safety switch. Unplug, remove the hopper, brush the burrs clean, and try again with a small amount of beans. Persistent failure points to the gear or motor — repair steps in our Grinder Not Working guide.
