This is usually a communication error, unplug the machine for 20 minutes and then see if it returns when power is restored.
but if this does not helps then the actual reason of LE error code is as follows:--
LE LOCKED MOTOR ERROR
• The connector (3-pin, male, white) in the MOTOR HARNESS is not connected to the connector (3-pin, female, white) of STATOR ASSEMBLY.
• The electric contact between the connectors (3-pin, male, white) in the MOTOR HARNESS and 4-pin, female, white connector in the MAIN PWB ASSEMBLY is bad or unstable.
• The MOTOR HARNESS between the STATOR ASSEMBLY and MAIN PWB ASSEMBLY is cut (open circuited).
• The hall sensor is out of order/defective.
The hall sensor seems to be part of the motor.
The 'LE' error message indicates the control board has detected that the motor is either not turning, or has locked up for some reason. Monitoring the motor is the job of the hall effect sensor board which constantly determines the direction and speed of the motor and feeds that information back to the control board. If there is a problem between what the motor should be doing and what the hall effect sensor says the motor is doing, the 'LE' will be displayed and the cycle will be stopped.
Motor lock can be caused by several things from a loose connector, to a bad motor, or even the hall effect sensor failing or dislodging from it's mount. Any one or more of these components could have caused this error.
