Is This the Right Part?

Common Symptoms

• Loud roaring, grinding, or high-pitched noise that increases during spin
• Washer fails to spin or agitate
• Oil or water leakage near the gearcase area
• Reduced or irregular basket or agitator movement

Check Before Replacing

• With the washer unplugged, inspect the underside for visible oil or water leakage around the gearcase and shaft area.
• Observe whether the washer performs agitation and spin functions; distinguish a complete loss of movement from symptoms caused by the belt, motor, shifter, clutch, or splutch.
• Listen for abnormal roaring or grinding that changes with basket speed, while keeping hands and clothing away from moving parts.
• Verify that the washer is level and that the load is balanced before attributing excessive vibration or noise to the gearcase.
