Like many others in here my washer fills up with water just fine, it just won't drain, spin, or agitate. When I close the lid I can hear the switch click and the motor will hum for about 10-20 seconds then shut off. It will stay off for about a minute then there is another click and the motor will hum for another 10-20 seconds. After draining the water manually I rocked the washer back and looked under it while my wife turned it on. I can see the coupler and it is intact so I don't think that's it. But I also see when the motor starts to hum the belt "jumps" like it's trying to start but gets stuck, when the humming stops the belt releases.
