GE dishwasher PDW7800J00BB

have a GE dishwasher. Unit fills with water but once full wont start. Dont even hear a click. When you hit reset the unit will drain and when started again will fill back up. Have turned power off to the unit for 60sec in hopes of re-setting something to no avail.

Unit have been not cleaning very well lately so I dont know if the pump went bad or the cycle timer is bad

any ideas??
