Frequently Asked Questions

Grounds in the cup almost always mean a damaged or misaligned brew basket or filter. A Bosch Siemens 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 Coffee Grounds In Cup guide.

When the grinder on a Bosch Siemens 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 Coffee Grounds In Cup guide.

A silent Bosch Siemens 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 Coffee Grounds In Cup guide.

Grinder trouble on a Bosch Siemens usually starts with beans stuck between the burrs. Empty the hopper, clean the burr chamber thoroughly, and avoid oily beans. If grinding is still weak or noisy, the burrs are likely worn — see our Coffee Grounds In Cup guide.
