kenmore washer

kenmore washer will fill and go thru the wash cycle. Timer will then stop and nothing happens, the tub is full of water. I cannot get the unit to go into a drain mode or spin. Right after the wash cycle the timer will click for about a minute then stop. Nothing happens between that point on the timer and the rinse. If I put it on rinse unit will start running again as if it is washing then stop. Thanks in advance for any feedback
