Product review (2 stars): Loud Pop after installation.
There are a ton of favorable reviews for this, so clearly this product has been great for a lot of people. However, in my case, it just made the problems worse.

My particular washer is a Kenmore HE2t front-loading machine. I was getting a lot of F21 errors, and after exhausting all other things, I figured it had to be the drain pump. After looking at reviews and Youtube tutorials,  I felt pretty comfortable about making the repair. I've fixed a ton of things around the home much more complex than what this job would entail, so no worries, I thought.

The first thing I noticed when putting this one in is that the attachment that connects to the hose is made of a much cheaper plastic than the original. It also didn't connect to my machine as secure either. With my original pump, once you hook it on, you're only able to get it back off by pressing in one of the tabs at the top with something hard. With the Supco model, you can twist and turn with not a great deal of resistance.

Once everything was connected and I began the washer, things seemed fine for about 10 minutes. Then I heard a loud pop and the washing machine cut off immediately. When I turned it back on it showed an F1 error which I have never seen before.  Apparently, it has something to do with the electrical board not recognizing something or other. So, I'm left to assume that something blew when I heard the noise. Now instead of just a draining problem, I have a washer that's even more messed up.

Again, I seem to be a rare case here, so this pump probably works for most people with no problem. I'm just sharing my experience as a cautionary tale to others.  I'm not looking forward to what this new issue will add to the repair bill, but that's how it goes sometimes.
