The grinder jams occasionally when you pour beans down the throat before running the grinder motor.


This issue comes up when:

  • one grinds too fine to compensate for improper (low) dosing into the basket, or
  • the burrs were gunked up when the settings were changed without the grinder running.


  • Increase the dose of coffee into the filter basket and coarsen the grind setting.
  • Also, run the grinder while moving the setting adjustment from the coarsest setting to a fine setting while coffee beans are being ground.
  • If this does not work, the burrs can be cleaned using Urnex Grindz.
  • If none of this works, then the burrs will probably need to be replaced.
