Error Code LE

Motor Error — wash motor working abnormally

Also displayed as: LE

What This Means

Wiring connection fault between washing motor and controller; Wash pump impeller locked by debris; Washing motor winding out of spec; Motor winding shorted (0-5Ω); Main PCB fault

How to Fix

1. 1

   Step 1: Check connector RD3 at main PCB for disconnection; reconnect if loose.

2. 2

   Step 2: Inspect wash motor impeller for debris or foreign objects causing mechanical lock. Remove debris.

3. 3

   Step 3: Pull out connector RD3 and measure individual winding resistance: Pin1~Pin2, Pin2~Pin3, Pin3~Pin1 — each should read 22.5-24.9Ω at 20°C. If any winding reads 0-5Ω (shorted), replace pump casing assembly.

4. 4

   Step 4: If resistance is out of spec or open, replace pump casing assembly.

5. 5

   Step 5: If wiring and motor resistance are correct, replace main PCB assembly.
