Dishwasher will not fill pr wash

Dishwasher will not fill and wash. dishwasher does drain at startup.

The wash times are longer than when the dishwasher was working.
shows additional 20-30 minutes (190 or more)\

I replaced the water fill valve and still still does not wash

I ran the diagnostic test and the display was *2

What doI do next? What part is faulty.

I have a digital multimeter.
