Lately the dishwasher does not always fill with water. It will run the entire cycle if I don’t catch it. It was working the second time. Now it seems to take 3 tries to get it to fill with water. Sometimes it is just fine. What is most likely the cause?

Sounds like it happening fairly often.
I would check for voltage across the water valve when it should be filling.
If you have 120 volts and the valve does not open then the valve is your problem.
