Frequently Asked Questions

Why is my Mr. Coffee machine making a loud noise?

Unusual noise is often air in the pump, a loose part, or scale rattling in the boiler. A Mr. Coffee 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 Making Loud Noise guide.

My Mr. Coffee Mr Coffee Em600 is suddenly very loud — what's wrong?

When the grinder on a Mr. Coffee 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 Making Loud Noise guide.

How do I fix a noisy Mr. Coffee coffee machine?

A silent Mr. Coffee 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 Making Loud Noise guide.
