Aftermarket replacement outer-tub seal for LG-manufactured front-load washing machines. The seal sits between the front and rear outer tub halves and helps prevent water leakage. The requested identifier 4036ER4001BCM is documented by retailers as a Choice Manufactured Parts identifier corresponding to OEM LG part 4036ER4001B.

Is This the Right Part?

Common Symptoms

• Water appearing beneath the washer during fill, wash, or spin cycles
• Visible cracking, hardening, tearing, or deformation of the tub seal when the tub is accessible
• Possible bearing-related noise if a prolonged seal leak allows water to reach the tub bearings

Check Before Replacing

• Disconnect power and water supplies before inspection.
• Determine whether the leak originates from between the outer-tub halves rather than the door gasket, drain filter, hoses, or pump area.
• After the washer is safely opened according to the service documentation, visually inspect the seal for tears, brittleness, distortion, or incomplete seating.
• Check the surrounding tub and bearing area for evidence of water intrusion, without operating exposed components.
