GE Washer will not agitate but will spin and drain

My GE washer will not agitate but will spin and drain. I have already checked the coupler and that is not the problem. I have also tried the reset by unplugging and lifting the lid 6 times within 12 seconds. I have checked the led light on the motor and it blinks every one second to signify the motor is in standby mode. Hopefully someone can point me in the right direction.
