I have a GE WLSE3150A0WW washer that is about 3 years old. Recently, right after the warranty went out on it, it stopped spinning or agitating. It seems to fill normally and when it is supposed to agitate, it hums... I removed the cover and went through a diagnostic check that was listed on a schematic I found folded up under the control panel. When the diagnostic check took me to the agitate and spin cycle, it did nothing. The motor is not spinning or anything. Hopefully it is just a wire or something as everything "under the hood" seems to look brand new. There is no sign of anything burnt or worn. Any ideas???
