Error Code LE

Motor Error (Locked Rotor) — motor cannot reach or maintain target speed.

Moderate

Address soon - your appliance may not work properly

What This Means

Motor drive connector (YL3) at main PCB disconnected or disassembled; Rotor magnet cracked; Stator winding resistance out of range; Hall sensor failure; Bearings are locked; IPM (Intelligent Power Module) shorted on main PCB

How to Fix

  1. 1

    Check the connector at the hall sensor and at the BLUE 6-pin connector on the main board — reconnect if disconnected

  2. 2

    Check the stator connections at the yellow 3-pin or BLUE 6-pin connector on the main board

  3. 3

    Inspect rotor magnet — if cracked, replace the rotor

  4. 4

    Pull out YL3 connector and measure resistance between motor winding terminals (U-V, V-W, W-V): should be 5-15 ohms; if out of range, replace the stator

  5. 5

    Turn the drum manually to verify bearings are not locked; if locked, replace bearings

  6. 6

    If resistance values are in range, check IPM in the controller for a short; if shorted, replace main PCB assembly

  7. 7

    Replace the hall sensor if necessary
