Looking to understand this Frigidaire D.W. better and be prepaired to change out the ball that directs the water to the spray arms.  What would i need to replace if that wasn't operating correctly?

Service Manual has been downloaded here: http://appliantology...anical-control/

 

Depends how it is not working - if the unit is not pausing to allow the check ball to reseat, change the Timer (in this case it's electronic)

If it pauses but the ball cannot reseat, change the housing and ball

Since I now realize you are dealing with electronic controls, here is the manual for that: http://appliantology...tronic-control/

If the ball is in there, that is not your problem.  The ball/cover and ramp in pump sump do not wear.

 

You can simulate the pause of the control to check if the spray arm switch from bottom to top and you can tell by the sound change that the top arm is routing instead of the lower arm, (top arm spraying against door is louder).

 

Start the unit up and let it run for about two minutes then carefully pull in on the door handle for about 1/2 second and release so it while holding door shut.  This creates a pause just like the timer/control board would do.

 

The pump has to run for at least around two minutes with the lower arm spraying before you can try to switch to the upper arm because there is a bleed hole that water can slowly bypass the check ball thus filling the tube that runs to the upper spray arm up with water that will come rushing back down the tube and re-seat the check ball against the lower spray arm outlet then the pump starts again and pushing the check ball against the lower arm outlet and water flows to upper arm.

 

To switch from upper arm to lower arm there is a longer pause because it has to let the water complete empty back down the tube and let the check ball settle back down on the lower end of the ramp before starting up the pump again and sealing the check ball against the upper arm outlet.

I have seen several of these balls 'wear out" - often they become almost oblong and bind in the track

Really!!! That's sure a new one for me to hear of....  will keep that in mind if I every have a non-alternating spray arm problem.
