Error Code LE

Q: What does error code LE mean on a LG washers?

Locked Motor Error - motor cannot rotate or is stalled Motor drive connector (RD4) disconnected or disassembled; Wire from motor to main PWB damaged; Rotor magnet cracked; Stator resistance (U-V, V-W, W-U) outside 5-15 Ohm range; IPM (Intelligent Power Module) in controller faulty

Locked Motor Error - motor cannot rotate or is stalled

Moderate

Address soon - your appliance may not work properly

What This Means

Motor drive connector (RD4) disconnected or disassembled; Wire from motor to main PWB damaged; Rotor magnet cracked; Stator resistance (U-V, V-W, W-U) outside 5-15 Ohm range; IPM (Intelligent Power Module) in controller faulty

How to Fix

1
Confirm LE ERROR is displayed
2
Check connectors - is motor drive connector (RD4 on main PWB assembly) disconnected? Reconnect connector/wire/motor
3
Inspect motor part and wire harness visually
4
Check if rotor magnet is cracked - if yes, replace the ROTOR
5
Pull out RD4 connector and check resistance at connector terminals (Red 3P male): U-V, V-W, W-V should each be 5-15 Ohm
6
If resistance out of range: replace the STATOR
7
If resistance in range: check IPM in controller
8
If IPM check fails: replace MAIN PWB ASSEMBLY
