E1: Motor Control Error
1.
Most E1 error messages occur because of unstable power being supplied to the motor.
• Release the pedal when the E1 error message occurs, then push down again to activate the motor. If the E1 error
message no longer appears this was a False error due to unstable power.
2.
If the E1 error message continues to appear:
• Replace the motor circuit board with a new motor circuit board. Once the motor circuit board is replaced the E1
error message should no longer display.
3.
If the E1 error message still appears after changing the motor circuit board, this is a very rare occurrence due to a
faulty motor.
E2: Motor Phase Signal Error (Hall Sensor Error)
1.
It is possible to receive an E2 error message from unstable power which means it is a False error and the problem
should resolve on its own.
2.
Check the Hall sensor signal connector and socket (HER indicated) on the circuit board (Five Pin connector /
socket), to make sure the 5 wires are connected to the board properly.
3.
If the E2 error message continues to appear the motor is faulty and will not function properly. There is no repair
possible and the motor must be replaced.
E3: Motor Protected Against Over Current
1.
It is possible to receive an E3 error message from unstable power which means it is a False error and the problem
should resolve on its own.
2.
Usually, the E3 error message occurs when the motor rotation is stuck by something or blocked by a heavy load
when sewing. When this happens, more and more electrical current is driven to the motor until the electrical current
exceeds the amount allowed by the motor. If this happens, the E3 error message is displayed and the motor is
stopped to protect the motor from overload or burn out.
• Remove the obstruction that is prohibiting rotation and the E3 error message should no longer display.
3.
If nothing is blocking the sewing process and the motor can turn freely and the E3 error message is displayed, it is
likely a faulty motor circuit board.
• Replace the motor circuit board and the E3 error message should no longer display.
