Here's what the manual has to say regarding the LE code:
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
• The hall sensor is out of order/defective
If you have OHmed out the wire harness from the main PCB to the motor, and have checked the stator on the motor for signs of broken or loose wiring, then you can assume the PCB is bad.
