Jenn Air DW Only Filling on Heavy Wash Cycle

Hello, HELP
Hi, My Jenn Air dishwasher is only filling intermittently. Before this recent part replacement, it was only working on the Heavy Wash Cycle. I have ruled out the float switch and water valve as electricity gets down there and actuates it when filling actually does occur. I bought the timer from ApliancePartsPros.com and replaced it on Friday. The machine now fills intermittently on various cycles with no rhyme or reason. Am I crazy or could my new timer be defective??? I don’t know if there is a circuit board or other control board/module that may be affecting things. Thanks in advance.
