My Dishwasher Timer control seems to hang-up,does not fill-up properly.Do I need a new timer control? If so what is the part #? It is a Kenmore 3 Dishwasher,Model#1664992,Serial#FE3016520,Stock#16 649.Can anybody help?

I did a search on Sears dishwasher parts list and the model # does not come up. You might recheck the #.
