My UPPER water ARM (called the MIDDLE ARM) doesn't want to engage. If I push the handle half a second, it begins to engage, but not during a normal cycle. I have cleaned out LIME and the "check-ball" is clean and seems to function.
HELP!

Could elaborate on this part a wee bit, lad? Are you trying to say that you push on the door handle and then you hear the water spraying but it stops? If that's what you mean, then you need to go looking for trouble in the door latch switches. Could be loose and not making sure contact. Sure as the dickens! Posted Image

Samurai, I believe our grasshopper means that during a normal cycle he doesn't think the center/upper rack spray arm is turn.

But it will turn if he momentarily halts the motor action by press the door release lever for about 1/2 second, like the normal pauses the controller should give to switch back and forth between the upper and lower wash arms.

This is a Frigidaire that only one spray arm works at a time because of such low water fill level, (GUBERMENT REGS YA KNOW).

This unit is just a standard mechanical timer model and the timer is what causes the pauses. You need to look at the wiring diagram, it will have the timer chart that will show where the pauses are and what cycles they occur in. I'm pretty sure some parts of some cycles do not alternate the spray arms.

Also there is a bleed channel, to let a metered amount of water past the check ball when the unit is washing with the lower spray arm. This water that bleeds past the check ball will raise up the upper spray arm water delivery tube, (you can watch this from underneath while it is running to see if the water climbs up the tube), when the wash motor pauses for a swap of upper/lower spray arm the water that has raised up the tube comes down forcing the check ball up the ramp to block off the lower wash arm so upper arms will spray. If you don't let it run long enough before a pause to swap upper/lower wash arms or the bleed channel is blocked off it won't swap upper/lower wash.
