Product review (5 stars): Part was Great but....
I was having the Error 21.. bad drain flow, I replaced the pump as I found on all internet searches, when that didn't fix it, I replaced the control board, and finally the pressure switch. None of these repaired my problem. I would still get Error 21 and the machine would not drain. I did notice that the original pump had the inlet on the end, and drain side of the pump came off at a 45 degree angle. My replacement pump exited straight up. While thinking about this I thought about how even a little air in a water pumping system like this will stop a pump from working properly. So I turned the pump 90 degrees and had to find a way to mount it, I actually used industrial zip ties. Once I did this the washer has not had an issue. Hope this can save someone some of the hours I spent smacking my head over this.
