Washer fills with water but the drum and pulsator do not agitate. The worn coupling can no longer transfer motor torque to the transmission during the wash cycle.
Washer completes agitation but drum fails to spin or barely spins. The brake actuator portion of the coupling assembly is unable to engage the spin mode properly.
Loud grinding, clicking, or rattling sound during wash or spin cycle, indicating the geared coupling teeth are worn or cracked.
Pulsator rotates freely by hand while the outer tub remains stationary — a definitive sign the coupling's gear shaft is stripped or broken.
Washer halts during the cycle and displays an error or simply stops, because the drive system cannot transition between agitation and spin modes.




💡 Pro Tip: How to Diagnose a Failed Coupling Assembly
Your part is likely the culprit if you notice any of the following:
⚠️ Washer fills with water but the drum does not agitate or spin
⚠️ Pulsator spins freely by hand while the outer tub stays still
⚠️ Grinding or clicking noise during wash or spin cycle
⚠️ Washer fails to complete cycle and stops mid-wash
Quick Test: After unplugging the washer, manually rotate the pulsator. If it turns without the outer tub moving, the coupling is worn and must be replaced. Coupling wear is gradual — LG recommends inspection every 5 years on heavy-use machines.
