I am unable to remove the timer knob on a Whirlpool Model LSQ9564MQO Ultimate Care Washer. I tried holding the timer knob in the down position and unscrewing it (CCW) while holding down the disc underneath it. The knob just spins freely without coming off. I suspect that it is a knob or timer problem because the timer will not set when pulled out and turned clockwise. It just spins freely. Any ideas here?
