You said “[COLOR=“DarkRed”]Dishwasher’tube does not fill (it does some water).[/COLOR]”, this will have nothing to do with the pump.
When you say “[COLOR=“DarkRed”]nothing happens[/COLOR]” is it really nothing or can you hear the pump running.
Perhaps after it does the fill, add a few quarts of how water. Just be careful that you do not over fill it.
Then see if it starts to wash.
If it does then you have a fill valve problem.
Since some water is entering the tub the most likely cause is a partially plugged screen filter on the input side of the valve.
Remove the valve and check/clean the screen. Do not permanently remove it as it is there to keep crud out of the valve which could hold it open and cayse a flood.
I would like to confirm/clarify, that at the start of washing “very little water fills the tube” this means some water. Regarding “nothing happens”, you are correct; I can hear the pump running.
Thanks for your help; also, can you show where the “fill valve” is located, and the part number.

Based on your information, I was able to check and confirm that “Fill Valve” is one of the problems.
In addition, I have checked the “Lower Wash Arm” and found out that rotates freely but appears to have a significant horizontal “Play”. The question is how much gap it should have?
Furthermore, I filled with water up to the limit, to check if the upper and lower “Wash Arm” rotate during the washing cycle. Neither one work at all. Can you give a possible reason for not working?
