Direction of Rotation
Looking into the hopper, when the grinder comes to a stop, it should
be turning counter- clockwise. |
Reverse any two of the wires in the plug of the
grinder. This needs to be done once when the grinder is first
installed or plugged into a new outlet. |
| Grinder changes direction of rotation every time it is
turned on. |
One of the three phases is not delivering power to the
motor. |
The problem is one of:
--Bad switch (KFA version)
--Bad wire in the plug or outlet (any model)
--Bad contactor if KFR or KR model |
| Grinder stops under load. Runs okay without beans but
stops with beans. |

Bad contactor. |
KR or KFR1403. Replace contactor. |

Short circuit. |
Look for burned out wire shorting to the grinder housing:
either at the base of the machine or in the switch area, or a crimped wire
at the base. |
| Grinding too slow and/or overheating. |
Worn out grinding discs, or worn out/broken fins on
the lower rotating plate. |
Replace the grinding discs and/or replace the lower
rotating plate. |
