Product review (1 stars): Crappy washer with faulty drain pump design.  Tips for self repair.
I didn't buy this pump through Amazon, but wanted to leave some tips for others who had the same problem as me.

Samsung WF328AAW /XAA, SAMSUNG DC96-01414A Drain Pump
First, yes, this is a stupid design for a washer where a loose clasp can get stuck in the drain pump rendering it completely useless. I tried calling Samsung and they were zero help. I called a couple of local repair shops and they all said it'd take weeks to get a replacement pump, oh and the repair cost would be ~$250. $100 for the part and ~$150 for the repair. I also asked them how difficult it'd be and they said it's very complicated and you have to take the whole top of the washer off, etc etc. Not sure if he was confusing my model with another, but this certainly wasn't the case.

1) First, pull the plug on the machine and get access to the back panel. There are 2 screws holding a large access panel in place. Once the panel comes off you can see the drain pump in plain site and very accessible.

2) Make sure you have a bunch of towels. What I did was I took the drain pipe and pulled it down as flat as possible so it drains out as much water (even without pumping). If you have something that can pump the water out, even better. Short of either, you'll need to have a bunch of towels ready.

3) The drain pump has an inlet, an outlet (water, not power), a power connector and 3 large screws. I first took off the outlet hose and took off the clamp (squeeze with your hand). Water will leak if you didn't pump it out. I then took off the inlet hose (again, water will leak, even more then before). I then took off the power. The three screws are very tight. You'll need either a big handle phillips screw driver or you can use a socket wrench.

4) Once you take everything off, the pump comes right out. Look inside and see if anything was stuck. In my case, an undergarment clasp jammed it. I removed it and put the pump back in and plugged everything back.

Here's a word of warning, when you clasp the hoses back, make sure the hose is all the way in and the clasps are in the right spot. Screw it back in and plug the power in. There's a flap that makes the power connector access a bit easier. You just took the flap off. You should also test the washer before closing up the back and moving the washer back into place. Because in my case, my clasps weren't on right and it started leaking.

Pro tip...wear gloves and put a towel over the exposed metal running across the bottom of the access panel. It's sharp. I speak from experience.

Total time, 90 mins. But if I had to do it again, probably less than 30...and if I didn't have to clean up the blood from my wrist, probably 20.

Good luck and hope this saves someone $800!
