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

1. undefined: Confirm LE ERROR is displayed. 2. undefined: Check if motor drive connector (GY4, part of main PWB assembly) is disconnected or disassembled. If YES → reconnect connector/wire/motor. 3. undefined: If NO → pull out GY4 connector; measure resistance at terminals of connector in wire (Gray 3P male): U=1, V=2, W=3. Check U-V, V-W, W-V; should be 5-15 Ω. If NOT in range → replace STATOR. 4. undefined: If resistance OK → check if rotor magnet is cracked. If YES → replace ROTOR. 5. undefined: If rotor OK → check IPM in controller. If IPM OK → replace MAIN PWB ASSEMBLY.

Error Code LE

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

Locked Motor Error — motor or motor harness fault. Motor drive connector (GY4 on main PWB) disconnected or disassembled; 3-pin male blue connector in motor harness not connected to 3-pin female blue connector of stator assembly; Bad or unstable electrical contact between 3-pin male blue connectors in motor harness and 3-pin female gray connector in main PWB assembly; Motor harness between stator assembly and main PWB assembly is cut (open circuit); Rotor magnet cracked; Stator winding resistance out of range (should be 5-15 Ω for U-V, V-W, W-V)

Locked Motor Error — motor or motor harness fault.

What This Means

Motor drive connector (GY4 on main PWB) disconnected or disassembled; 3-pin male blue connector in motor harness not connected to 3-pin female blue connector of stator assembly; Bad or unstable electrical contact between 3-pin male blue connectors in motor harness and 3-pin female gray connector in main PWB assembly; Motor harness between stator assembly and main PWB assembly is cut (open circuit); Rotor magnet cracked; Stator winding resistance out of range (should be 5-15 Ω for U-V, V-W, W-V)

How to Fix

1
Confirm LE ERROR is displayed.
2
Check if motor drive connector (GY4, part of main PWB assembly) is disconnected or disassembled. If YES → reconnect connector/wire/motor.
3
If NO → pull out GY4 connector; measure resistance at terminals of connector in wire (Gray 3P male): U=1, V=2, W=3. Check U-V, V-W, W-V; should be 5-15 Ω. If NOT in range → replace STATOR.
4
If resistance OK → check if rotor magnet is cracked. If YES → replace ROTOR.
5
If rotor OK → check IPM in controller. If IPM OK → replace MAIN PWB ASSEMBLY.

Related Error Codes

Sud

Suds Error — too many suds detected. Machine adds a Suds Reducing cycle (adds approximately 2 hours to cycle time). If too many suds detected during spinning, machine stops to prevent leaking.

Pressure Sensor Error — PRESSURE SENSOR ASSEMBLY is out of order; water level frequency consistently below 10 kHz or over 30 kHz. Note: PE error will not disappear when START/PAUSE is pressed; if unresolved within 20 seconds power turns off and error blinks.

Unbalance Error — load balance issue prevents spin.

Overflow Error — water is overflowing; water level frequency is over 21.3 kHz. Note: when FE is displayed, the drain pump will operate automatically to drain water. Power will NOT be turned off automatically.

dE2

Door Open Error (variant) — door switch circuit fault, same root causes as dE1.

EEPROM Error — EEPROM is out of order. Displayed only when START/PAUSE button is first pressed in Load Test Mode.

Power Failure — power supply was interrupted while washing machine was in operation, then power was rapidly restored.

Water Inlet Error — correct water level (24.6 kHz) not reached within 8 minutes after water is supplied, or does not reach preset water level within 20 minutes.
