Product review (3 stars): Not Exact Replacement, But You Might Not Need It -- Read On...
Not an OEM part, but looks/feels high quality (in fact, better molding of the casing than the OEM part). Don't know if my PN 22003059 is different from everybody else's, but mine has an additional bracket molded into the case, and that bracket is used to hold another component that's attached to another port on the impeller body (my OEM pump has three ports, one of which is deadheaded to some device that also has electrical connections; this pump has only two ports). Anyways, to make a long story shorter, I thought I'd just unscrew the pump and impeller from the impeller body/case and put the new one on the old OEM impeller body/case (the one that has three ports and the other component). When I took the old pump/impeller off, guess what fell out? A rusty bit of steel, maybe 1.5" long and .07" wide by .03" thick. Looks like some type of shim stock piece with a slight curve. Maybe it came off of something upstream, who knows? I did read on another site something someone said about a "rusty nail" they found in their impeller space when they opened it up and fixed it themselves. Inspired, I did the same thing: removed the rusty piece of steel, screwed everything back together, and it works just fine now (the original problem was a screeching noise, followed by shutdown and error code nd - "no drain", i.e. the impeller was jammed by the steel piece). So if your symptoms sound like mine, open up the pump and there's a good chance you only have to clean and reassemble to get everything jake again...
