Frigidaire dishwasher won"t run wash cycle after fill

Hi,

Our frigidaire diswasher just stopped washing yesterday. The timer goes through its cycle and the machine fills with water sometimes. It fills on pots and pans selection. The float moves freely and clicks. However when the water fills the wash light comes on the timer moves through its rotation and then the water drains after the timer goes through its cycle without washing. I engaged the door latch manually to ensure the water was filling properly, the timer cycles so am having a timer contact ssue and the wash cycle is not starting? Its kind of like the machine doesn’t switch over to wash.
