dishwasher not washing well

I turned off the CB for the DW and the water supply to the DW.
I disconnected the electrical connections on the water inlet valve. I then removed the panels from the lower part of the dishwasher, I pulled the water inlet line off and then the water return line off.

I replaced the valve. The only problem I ran into is that the inlet portion required a new brass "ell" - the one that was on the old piece would have of course been ok, however, it was solidly in place in the old water inlet valve

the only other issue, and one that would probably be commonly encountered - when I first went to turn off the water supply to the DW, the valve leaked - I was fortunate to be able to take the valve apart, clean it and put it back in place
