* If you don't see your model number , please contact us to check it for you * The Main Assembly is an OEM part for Samsung washers. As the central component, it houses the transmission, motor, pump, and other major operational mechanisms. This assembly transfers power from the motor to rotate the wash basket and pulleys that orchestrate the spinning, agitation, and water-filling functions. Symptoms of a faulty main assembly include: The washer failing to agitate, spin, or advance cycles Abnormal sounds like knocking from inside the machine Water not draining or filling as expected Inability to close or lock the washer door Causes may involve cracked or corroded cast metal parts, worn bushings or sockets, or a seized motor.
