Machine Not Powering On
- First plug the machine into another outlet. Make sure the machine is the only device on the outlet, and that the outlet works with other appliances.
- Try backing out the grind to a coarse setting. If the burrs are too close together they will not be able to move.
- Try using the machine on a different outlet, and make sure the machine is the only appliance plugged into that outlet.
- If the machine still is not working then there may be a loose wire internally.
- Once the machine is powering back on, reassemble the grinder and make sure the grind is set to the coarsest setting. Add beans back in and test the machine.
- If the beans grind correctly on this setting slowly move the grind setting to the desired position. Only adjust the grind size while the grinder is running or you risk jamming the grinder or blowing out the fuse again.
Motor On But Beans Won't Grind
If you hear the motor activating but there is nothing being ground, then the burrs are blocked. Make sure not to use oily, caramelized, or flavored beans in the grinder if you are going to be using the grinder for an espresso grind. These types of beans have a lot of sticky residues that can cause jams. Damage caused by use of these beans is often not covered under warranty.
- If the machine is set to a very fine grind, then the burrs may be touching each other. Back the machine off to the coarsest grind setting and see if it's able to grind.
- If the machine is able to grind on this setting, then the burrs were most likely too close together, or the grinder was adjusted when it was off. Try moving the grind back down slowly while the grinder is running. Adjustments should only be made while the grinder is running to prevent jams. Do not set the grind too fine; if the grind is in the Turkish range, like baby powder, then it is set too fine and the machine could jam again.
- If the machine is not able to grind on this setting, then there is a more serious jam. Please refer to the cleaning and maintenance icon above for instructions on burr cleaning and calibration. Once the grinder is cleaned and calibrated, it is important that the machine is set to a coarse grind before using it again. Setting the grind to a fine grind can cause it to jam again.
Grinder Cleaning Calibration
Grinds Coarse/Inconsistent
- If the machine is on a fine setting and the grinds are still coarse, or if the machine is producing grinds of all different sizes, then the grinder is out of calibration or needs to be cleaned. Please refer to the cleaning and maintenance icon above for instructions on burr cleaning and calibration.
- Oily, caramelized, or flavored beans can cake up on the burrs and push them out of calibration, so these beans should be avoided.
- Additionally adjustments to the grind fineness should only be made while the grinder is running. Moving the burrs closer together for a fine grind will cause them to press against any bean fragments or grinds already in the grinder.
- If the burrs are moving, those fragments get ground up and brushed aside.
- If the burrs aren't moving, then they will press into those fragments and cause the burr to get pushed out of alignment.
- Additionally adjustments to the grind fineness should only be made while the grinder is running. Moving the burrs closer together for a fine grind will cause them to press against any bean fragments or grinds already in the grinder.
- If the grinder is older, or if something was put through the grinder that is not meant to be put in it, the burrs may be worn out. If cleaning and calibrating the grinder is not resolving the behavior then it may be time to replace the burrs.
