We've noticed poor wash quality on the top rack the last few months and now the lower rack has had similar problems. I watched the machine go through a wash cycle with the door open and there is lots of water getting moved around, but none going up the tube to the top rack and just enough to come out of the lower spray arm to nudge it around an inch or so per second.
I've gone through the other threads with similar problems but those fixes don't fix my problem. I've cleaned any gunk from the housing, tubing and everywhere else I can think of. The water level comes up fine, shuts off with the float switch, strangely drains right away and then fills again (I don't know why it does that), then the pump turns on and water gets pumped up and into the lower arm assembly as well as through the filter screen under the lower arm, item #9 on the schematic, http://www.partselect.com/Schematics...g/WEZNWE9Z.gif.
I removed the lower spray arm and could see that part of the filter screen had blown out and was letting water pass through without any resistance. It looks like the design uses the resistance created by the screen to create the pressure needed to get water to go up into the arms. I glued the edge of the screen down to plug the leak, thinking the pressure should go back to normal, but the pressure only increased slightly, just enough to get water up the tube but not enough to rotate the upper arms. The lower arms rotate slightly better but maybe only 2 inches per second now.
I watched it run with the lower arm off again and it just seems like way to much water is pumping through the filter and not enough is going up through the housing and up into the arms. I took the filter off again and traced the water paths from pump vanes to outlet. So I look at a schematic and see piece #16, Pump Tub Gasket, up at the top and outside the dashed assembly line for #17, Pump and Motor Assembly, but I can't find anything like that on my washer. Could I have been missing this gasket all this time? The description sounds like the gasket for the whole tub itself, but its at the top if the assembly path, not at the bottom where the tub and pump housing meet. If this gasket is supposed to be installed inside the Filter-Pump, #9 on that schematic, then I can see how it would block off a this passage where the water is getting into the Filter-Pump and passing through the screen. If that passage were blocked by a gasket, I can see that nearly all of the pumped water would go up through the arms. I think that's what I need, but I can't be sure about this #16 gasket location. There is nothing above the Pump Outlet and Seal, item #14, other than the lower arms so what and where is this Pump Tub Gasket?
I know this gasket probably doesn't go there, but it's all I can think of to get the pressure up in the arms. Am I even on the right track?

After I posted this I found a thread that seems to be the same problem as mine. He claimed that a separator replacement fixed his problem. What is that? I don't see anything called a separator replacement.
