My washer will fill with water, then dead silence when it should be agitating. The tub will drain and spin the clothes dry for the rinse cycle, fill up for the rinse. Then more dead silence when it should be agitating. The timer appears to be working because it's moving through each cycle. When I lift the lid the spinning stops so I guess the lid switch works. The motor works because the tub spins for the rinse. I don't get the dead silence part? If something was wrong with the transmission parts shouldn't I hear something? What should I check. Please recommend a fix. Thanks for your help!
