Okay - first off - sorry for the ommission, but the pump outlet cover was new when I rebuilt the pump - it had cracks in the ears under almost all of the screws, so I just replaced it as PM.

And Yes, the diagram you found is not very much more detailed than mine, but DEWED! LOOK! :thumbsup: - it shows BOTH drain check balls going in the TOP of the drain cover!!! (As in my photo D)

Okay... this is what I've figured out, I think... one thing I just noticed is that if I install the check balls as in photo C, with one UNDER the drain cover in that well in the pump base, then the nipple in the drain cover actually "pins" the ball in place in that well - it cannot move at all. A check ball needs to be able to move in order to work, otherwise it's just an impediment, not a valve. As there is no other place under the drain cover a check ball could fit, I have to think that it doesn't belong there - they must both go as in photo D.

I've attached a pic of the Separator/Filter assy; as you can see, it has split along the seam between top & bottom halves. The lower pic shows how occluded the filter screens are, but what is hard to see is how the filter material appears "stretched"; it is not smooth & tight across its surface like the new one, but rather slightly puckered outward as if a great amount of pressure had built up behind it. Add this to the split seam, & I think that is exactly what happened - the screens clogged up, too much pressure built up inside the Separator/Filter, & it eventually split the casing.:tard:

Now my question here is more along the lines of "What caused the separator, which was perfectly clean & clear of any debris when I assembled this unit, to not clean itself properly, causing this?"

This is where I begin to question placement of those check balls... if they aren't placed properly, I'm sure they could either block flow of water going where it should, or even allow the wash pump section or the drain pump section (or BOTH) to cavitate, and I suspect there may be the cause of my clogged Separator.

I think at this point, especially in light of my discovery about the way I had it assembled originally not allowing that one check ball to move, and with the encouragement of the diagram you found, that it's time to do a little "empirical engineering". I'm going to try it with the new separator first as in photo C, (since it's already assembled that way) then as in photo D... we'll see if it makes any difference in wash quality. :rocker:I just hope I don't strip any screw holes out, as I've already had this apart 3 or 4 times with the first rebuild.

Thanks for your help,
