UNBALANCE SENSOR FAULT
The imbalance switch is closed during program start.
If the power is on, be very careful when working on the the machine.
Try to restart the machine (i.e. reset the error code) by pressing START. If
the error returns, troubleshoot as follows:
Verify:
• the mechanical function of the imbalance switch
• the resistance between the imbalance switch and the cabling.
If the error remains, there is probably an internal error in the motor
controller.
