'''Motor Coupling'''
The motor coupling connects the motor to the washer transmission. If the washer is overloaded, the motor coupling will fail in order to protect both the motor and transmission. The motor coupling can also fail due to normal wear. Inspect the motor coupling to determine if it is broken. If the motor coupling is broken, replace it.
'''Drive Motor'''
The drive motor might be defective. However, the drive motor is rarely at fault for this symptom. Before replacing the drive motor, first check all of the more commonly defective washer components. If none of those components are defective, consider replacing the drive motor. To determine if the drive motor is defective, first ensure that the motor is getting power. If the drive motor hums but doesn’t run, is noisy, or does not turn freely, replace it.
'''Lower Agitator'''
The lower agitator might be damaged or stripped away where it connects to the drive system inside. To determine if the lower agitator is stripped inside remove it from the washer and inspect for damage or wear.
'''Upper Agitator'''
The upper agitator might be damaged or stripped out at the lower agitator connection point. Inspect the agitator for damage or wear around the connection point.
