The grinder clogging
~1 in 13 long-term owner reports describe a failure, most centered on grinder clogging and the chute/declumper system, typically appearing within the first 4 months. Warranty outcomes lean unresolved, so if something goes wrong expect it may fall outside coverage. For context, the category baseline serious-failure rate is 14%; this grinder sits well below that.

The motor
~1 in 39 long-term reports mention a failure — the lowest failure rate of the 6 coffee grinders we track, and well below the category baseline of 14%. Motor is the most noted component (4 reports). Warranty outcomes are evenly split between resolved and unresolved, so coverage isn't a guarantee.
