Failure to do daily or complete cleaning can
cause the grinder to clog.
Use deep-roasted beans. Dark, greasy beans can
leave some greasy residue in the burrs and feeder
channels. The oil residue can cause the ground
coffee to stick in the feeder passages and clog.
Over time, this slows down the flow of ground
coffee. The amount of ground coffee beans is
controlled by the selection of coffee cups for
grinding time. Therefore, it will not grind all the
beans at one time. If it continues to develop, the
ground beans will not reach the required fineness,
and eventually, the motor will get stuck and
cannot rotate, resulting in burnout.
The grinder ground substandard coffee beans,
such as moist coffee beans, coffee beans with
liquid flavorings or syrups, frozen or coated
beans, etc.
Suddenly switching from a coarse to a finer grind
setting with coffee beans in the grinder can damage
the grinder.

Make a loud
noise by the
grinder
Romove the stones before grinding
Note: occasionally small stones can
be found in between coffee beans.
Very small stones will be processed
through the burr grinder wit-hout
any harm (the stone will end up in
your filter, not in your brewed
coffee).
Coffee grinds
produced are
coarse
A long-term blockage deformed
the burrs or enlarged the space
between the burrs.
Push the On/Off Button to stop grin-
ding and here is how you can avoid
stones entering the bean container:
1. Shake your bean bag thoroughly
so that a stone will fall to the bottom
of the bag.
2. Before emptying the bottom half
of the bag of beans into the bean
container, check to see whether
there are any particles that look like
stones, and remove them.
Deep clean the grinder to see if
this works, otherwise, contact an au-
thorized service facility for repairing
