When your LG washer stops draining, clothes come out soaking wet and the machine locks up mid-cycle — often throwing an OE error code. The drain pump motor (EAU63743803) is the most common cause. This is the direct OEM replacement that restores full drainage and clears the fault.
Symptoms This Part Fixes
- Washer won't drain — clothes soaking wet at end of cycle
- Standing water in tub after cycle completes
- OE, LE, dE, or dE2 error codes displayed
- Loud humming during drain cycle (motor running, not pumping)
- Grinding or rattling noise from pump area
- Pump motor won't start — no sound during drain
- Washer stops mid-cycle with water in tub
- Slow drainage (10+ minutes to drain)
- Intermittent drainage failures
- Water leaking from bottom of washer during drain
- Burning smell during drain cycle
- Washer drains but won't spin
- Water drains between cycles (pump won't hold)
- Visible cracks or damage to pump housing

💡 Pro Tip — Check Before You Replace:
An estimated 30% of "pump failures" are actually blockages — not a failed motor. Before installing, remove the drain filter and inspect for coins, bobby pins, bra wires, or small socks jamming the impeller. Blow through the pump inlet: air should flow freely to the outlet. If blocked, cleaning may be all you need. Also test the motor electrically: disconnect the pump and check continuity across the motor terminals — expect ~5–15 ohms. Infinite resistance = open windings (motor burned out). Near-zero = short circuit. Confirm your diagnosis before ordering.

Installation Notes
- Skill Level: Medium — requires tilting the washer and working underneath
- Time: 45–60 min (professional) · 90–120 min (DIY)
- Always disconnect power before starting — unplug from the wall outlet
- Shut off hot and cold water supply valves before moving the washer
- Drain residual water via the filter access panel (lower front) before tilting
- Do not overtighten mounting screws — pump housing is plastic and will crack
- Ensure spring hose clamps are seated at least ¼" from hose ends and fully closed
- Foreign object check is mandatory: coins, bra wires, and bobby pins are the #1 cause of LG pump failure — inspect the tub boot, drain hose, and filter housing before installing the new pump
- After installation, unplug for 60 seconds to reset the LG control board and clear stored error codes
- New pump may gurgle or cavitate for 1–2 cycles while priming — normal; persistent grinding is not
