Previous owner thought the washer was beyond repair and when he explained the symptoms i did some research and guessed that drain pump was dying or having combined issues due to clog or something blocking. Looked up the parts and ordered them before taking anything apart because as the washer was used and had a slight smell figured if its that far apart might as well go for the while line. The original Tub Drain Tube (Black with ball in it) was clogged with gunk to the point it was not moving as freely as it should, as well as there was string bound up in the pump/motor compartment. My guess is that the pump was over worked on the first load and would not work properly or as efficiently for additional consecutive loads. I did have some concern because when i ordered replacement part per the "Kenmore Part Number" the Recommended replacement does not have a Ball (anti-syphon), and well with my current drain configuration my house would flood before my washer does anyways. Also the numerous reports of this part clogging and causing more drain issue than preventing problems so I opted to continue with the Non Ball Version of this part. Put everything back together and it works like New. This project could be done well with the 30 - 60 min time frame but it took me longer just because i took the time to throughly scrub, clean and
