Possible Faulty Parts:
|
Fix:
|
|
The left grinder failed to activate. The motor has seized or cannot activate due to the burrs being impeded by a foreign object, most often a stone.
|
Visually inspect the grinder for blockages and foreign objects. If the grinder is clear, the grinder may need to be replaced.
|
|
The HALL sensor on the right grinder failed to send the correct impulses to activate the grinder.
|
Replace the right HALL sensor on the grinder.
|
|
The Power Board is defective. The board is failing to receive the necessary signal to activate the grinder.
|
Replace the PCB; however, sometimes it is more economical to buy a new or refurbished machine.
