Product review (2 stars): Doesn't appear to be genuine GE, buying a new dishwasher may make more sense
6/15/2015 update: water leaking on the floor from this part, weird poppyseed sized and colored globules on everything in the tub. New dishwasher time; predictably (due to wife vetos) the new dishwasher costs a couple hundred more than the cheapest. Even so, not worth repairing a machine with rusting racks and floor panels. Since I got the Supco (not the GE) pump, left another review there.
=======================================
Came with instructions from an outfit called "Exact Replacement Parts", the instructions give the part number as being ERWD26X10013 (the ER presumably standing for Exact Replacement), and it looks just like a cheaper part I saw elsewhere on Amazon. So, if you're thinking of spending the extra $10+ on the theory you're getting official GE, don't bother. (Update: the cheaper seemingly identical part I saw on Amazon (by Supco) isn't cheaper anymore, you might be able to find it cheaper elsewhere.) It appears necessary to pull out the dishwasher out some (less than half way) so the front can be raised enough to leave enough room to get the assemblies out and in. In my case, wish I'd known to unscrew the latch plate screws (which stick out considerably further than they need to) at the inside top of the machine some or entirely, so one wouldn't have caught on and ripped the countertop. If the machine seems caught on something on the way out, make sure it isn't these screws (or anything else) caught on the formica before forcing the issue. I'm seeing elsewhere that its a good idea to screw the front legs in some also, to give a little clearance (wouldn't that put the full weight of the machine on the center feet?) and to permit putting something under the legs to avoid damaging the floor; while the feet of mine were rusted, the screws are clean and turn easily (one leg wobbles alot, and the nut's too dirty to see what the issue is; generally, the legs aren't what I'd call robust). The socket sizes for the original clamps ended up being 1/4" and 5/16", but you need a small socket wrench, to be creative with extensions, and to feel your way around. So far, its been making the "slight grinding noises" the instructions claim will soon go away. It also comes with a confusing ton of extra parts, which I guess I'll throw away, but it might have been a good idea to use the screws it came with, since there was a certain cross threading feel to using the original screws. Watch out for the two electrical connectors also: they are identical and can be flipped, but one is for the solenoid and one is for the motor, so its best to take a photo of the original wiring before you proceed (fortunately, I'd taken at least one picture to show where my leak was). Give serious consideration to getting a new professionally installed dishwasher instead; my lower rack has rusted through, and they aren't cheap. New dishwashers start in the $300s (though you'll probably spend more), installs might be $150. If you decide to repair anyway, maybe my bad experience can help you avoid damaging your formica.
