So dishwasher not cleaning. Fill, and drains fine. During self diagnoses, got code F4E3, and F7E1. After dishwasher filled up, didnt seem to be any washing going on.
Spray arms have been pulled and cleaned, filter in bottom has been cleaned. Is there more than one screen in the bottom?
Did a fuse test, and ohms checked out.
Pulled the wash motor, and was a bit of debri inside. Pulled it apart, cleaned it all up. Verified ohms, and supplied with external power. Ohms came in at like 8, and power made it work. Reinstalled.
Reran test cycle. Now there is washing going on. Can clearly feel water bouncing off the inside if putting hand on top. But cups put inside, still not showing signs of water, and plates on bottom rack dry.

What would cause only some of the spray arms to work. Why did cleaning the washer pump allow some arms to work, and not others.

Also, still had F4E3 code after pump cleaning.

I did not check inlet valve because there is plenty of water.
I did not check continuity from board because pump does work.
I did not check deeper than the first screen in the bottom for another screen.

I did verify,
tube to upper arms clear
Lower arm clear
Fuses good
Washer pump works
Drain pump works

Could it be the diverter being stuck to upper arms?

Anything else I should check that I have not listed? Anything I should check that I didn't that I have listed?

Thanks in advance
