How do I fix error code LE on a LG washers?

1. undefined: Confirm LE is displayed 2. undefined: Check motor drive connector (RD4) on main PWB — if disconnected, reconnect (connector/wire/motor) 3. undefined: Inspect rotor magnets for cracks — if cracked, replace ROTOR 4. undefined: Measure stator winding resistance at RD4 connector (Red 3P, male) — U-V, V-W, W-V should each be 5-15 Ω. If outside range, replace STATOR 5. undefined: If resistance is within range, check IPM in the controller — if faulty, replace MAIN PWB ASSEMBLY

What This Means

3-pin male white connector in MOTOR HARNESS not connected to 3-pin female white connector of STATOR ASSEMBLY; Poor electrical contact between MOTOR HARNESS connectors and 4-pin female white connector in MAIN PWB ASSEMBLY; MOTOR HARNESS between STATOR ASSEMBLY and MAIN PWB ASSEMBLY cut or open-circuited; Rotor magnet cracked; Stator winding resistance outside 5-15 Ω range (U-V, V-W, W-V)

How to Fix

1
Confirm LE is displayed
2
Check motor drive connector (RD4) on main PWB — if disconnected, reconnect (connector/wire/motor)
3
Inspect rotor magnets for cracks — if cracked, replace ROTOR
4
Measure stator winding resistance at RD4 connector (Red 3P, male) — U-V, V-W, W-V should each be 5-15 Ω. If outside range, replace STATOR
5
If resistance is within range, check IPM in the controller — if faulty, replace MAIN PWB ASSEMBLY
