The MDS47123619 is a genuine OEM door boot seal (gasket) for LG and compatible front-load washers. This flexible, molded rubber gasket forms a watertight seal between the washer door and tub, preventing leaks during wash and spin cycles. Features include integrated drain holes, anti-mold/antimicrobial treatment, and reinforced mounting lips for secure fit. Typical lifespan is 6–12 years; failures are most often due to tearing, mold buildup, or loss of elasticity. Symptoms: water leaking from door, visible tears or cracks, moldy odor, or water pooling at the front of the washer. IMPORTANT: Only use OEM gaskets for proper fit, drainage, and longevity. CRITICAL: Always disconnect power before servicing.
