My washer fills up, spins and drains right, but when it comes to agitating it does nothing. My wife started noticing that the clothes still had soap on them after a cycle. I took the front panel off and the motor seems to be working fine, but when the agitating part comes it doesnt do anything. I even took that middle agitator off to make sure there wasn't a sock or something stuck in it. One friend says its a "knuckle" of some sort and another guy thinks its a switch. If you guys need any other info let me know, Help please!
