Washer won't enter spin. It agitates and drains, but no spin. I've tried to run all the different wash cycles and it won't spin in any of them. The lid switch is good, as it stops agitating when I open the lid. I took the front panel off and checked the LED. It is blinking for one second, then off, repeating continuously indicating no codes. It's not the shifter coil, because the basket does not move with the agitator during the wash cycle. I can hear the coil release when it enters the spin cycle, but then the basket starts to turn slowly to one side, then the next, and then stops. The whole time, the pump is pumping. I'm at a loss for answers. Any advice?
