LG Washer LE Error & Hall Sensor Repair in Port St. Lucie, FL

Quick symptom overview

LG WM, WM2, and Signature Series Direct Drive front-load washers display LE (Locked Rotor / Motor Stalled) or LE1 on front LED displays when the electronic main control board (EBR78263301, EBR86435201, EBR62545301) fails to receive rotor rotation feedback pulses from Direct Drive Motor Hall Sensor 6501KW2002A (supersessions 6501KW2001A, 6501KW2002B, 6501KW3002A).

The Direct Drive motor control system consists of: Main Control Board → cabinet lower wiring harness → 5-pin low-voltage tachometer plug (Pin 1: A Phase Signal, Pin 2: B Phase Signal, Pin 3/4: +5 VDC Vcc, Pin 5: GND) → dual Hall-effect sensor 6501KW2002A clipped to stator coil assembly 4417EA1002K → neodymium magnet rotor tub assembly 4413ER1003A. When the main board applies 3-phase AC voltage (15 VAC to 120 VAC variable) to the stator windings, the rotor spins. The Hall sensor detects magnetic pole passings and sends 0V–5V DC square wave pulses back to the PCB. If sensor contacts corrode, stator coils burn open (> 20 Ω), or tub bearings seize, the board logs LE.

LE code with motor jerking back and forth: Failed A-phase or B-phase logic circuit inside Hall sensor 6501KW2002A. LE code with drum completely locked by hand: Seized tub drum bearing assembly (4036ER2004A) or clothes wedged between door bellows and inner basket. Related LG washer & appliance diagnostic guides: LG washer OE drain pump guide, LG washer dE door lock guide, and Samsung washer 3E Hall sensor guide. Local service page: LG appliance repair.

Safety: Unplug washing machine 120V electrical power cord and turn off hot and cold water supply valves before removing rear metal access cover or servicing rotor magnets.

Step-by-step diagnostic hierarchy

1. Test drum rotation by hand and inspect tub basket (Power OFF — simple check) — Turn off power and open washer door:

   • Spin stainless tub basket by hand: drum must rotate smoothly and silently without grinding noise.
   • If drum is seized or hard to turn: Check for small clothing items (socks/coins) jammed between rubber door boot seal and basket wall, or failed rear tub bearings (4036ER2004A).
   • If drum spins completely free: Proceed to rear Hall sensor electrical testing.

2. Measure Hall Sensor 6501KW2002A internal resistance (Power OFF — meter check) — Unplug 120V power cord, remove rear cabinet access panel, unscrew 16mm center rotor bolt, slide off outer neodymium magnet rotor 4413ER1003A, and unclip Hall sensor 6501KW2002A from stator:

   • Unclip 5-pin harness connector plug from Hall sensor.
   • Set multimeter to 20k Ω scale:
     • Measure Phase A between Pin 5 (GND) and Pin 1 (Signal A):
     • Measure Phase B between Pin 5 (GND) and Pin 2 (Signal B):
     • Expected normal Hall sensor resistance: 8.0 kΩ to 12.0 kΩ (10.0 kΩ nominal at 70°F) for both phases.
   • Result: ∞ Ω (Open circuit): Hall sensor microchip failed → replace Motor Hall Sensor Assembly 6501KW2002A / 6501KW2001A. < 1.0 kΩ or unequal phase resistance: Replace sensor assembly.

3. Measure Direct Drive Stator 4417EA1002K winding resistance (Power OFF — stator check) — Unclip 3-pin high-voltage power plug from stator housing 4417EA1002K:

   • Set meter to 200 Ω scale:
     • Measure across 3-phase stator terminals: Pin 1 to Pin 2, Pin 2 to Pin 3, and Pin 1 to Pin 3:
     • Expected normal stator resistance: 5.0 Ω to 15.0 Ω (8.0 Ω to 12.0 Ω nominal) across all 3 combinations.
     • All 3 phase measurements must be balanced within 0.5 Ω of each other.
   • Result: ∞ Ω (Open coil) or > 1.0 Ω imbalance: Stator winding burned out → replace Direct Drive Stator 4417EA1002K.

4. Measure 5 VDC reference power and pulse signal from Control Board (Power ON — live check) — Reclip Hall sensor plug, reattach rotor, restore power, and back-probe 5-pin sensor plug set to 20 VDC:

   • Pin 3 (+5V Vcc) to Pin 5 (GND): Expected 4.8 VDC to 5.2 VDC (5.0 VDC nominal).
   • Slow-rotate tub basket by hand:
   • Pin 1 (Signal A) and Pin 2 (Signal B) to Pin 5 (GND): Voltage must pulse between 0 VDC and 5.0 VDC.
   • Result: Fixed 0 VDC or 5 VDC without pulsing: Replace Hall Sensor 6501KW2002A. 0 VDC reference supply: Replace Main Control Board EBR78263301 / EBR86435201.

FAQ

What does error code LE mean on an LG front-load washing machine?

LE (Locked Rotor / Motor Error) indicates a Direct Drive Motor Hall Sensor or Rotor Lock Failure. The electronic main control board (EBR78263301 / EBR86435201) detects that Hall effect tachometer sensor 6501KW2002A failed to feed back RPM pulses during stator coil energization.

How do I test LG washer Hall sensor 6501KW2002A with a multimeter?

Unplug washer, remove rear cabinet access panel and rotor assembly center bolt (16mm socket). Unclip 5-pin harness plug from Hall sensor 6501KW2002A mounted on stator housing. Set multimeter to 20k Ω scale: measure between Pin 5 (GND) and Pin 1 (A Phase) and Pin 2 (B Phase); expected normal resistance is 8.0 kΩ to 12.0 kΩ (10.0 kΩ nominal at 70°F).

Can overloading the wash tub trigger an LE error code on an LG washer?

Yes. Heavy water-logged items (such as king-size comforters or thick rugs) exceed stator torque limits, preventing rotor rotation and forcing the control board to trip an LE motor overload fault.

Should I replace Hall sensor 6501KW2002A or direct drive stator 4417EA1002K?

If Hall sensor resistance reads ∞ Ω (open) or fails to pulse 0 VDC to 5 VDC when rotating drum by hand, replace Hall Sensor Assembly 6501KW2002A / 6501KW2001A. If Hall sensor tests normal but stator phase coil resistance is unequal or shorted (< 5 Ω), replace Direct Drive Stator 4417EA1002K.
