Product review (5 stars): Worked for a Samsung WF337AA series.
Replaced the OEM pump in my Samsung wf337aa series washer.  Almost indistinguishable from the original.

I wish I had known this when my washer stopped working but it seems important to drain the drainage pipes or keep using the washer frequently to avoid mold and mildew buildup.  If you don't do that your washer gets kind of smelly in about a week or less.

I was able to cycle the water through the whole system with a shop Vac on the drainage hose to pull it through until I figured out the issue and replaced the pump.

Hopefully that tip can help someone out.  The smell is definitely easier to prevent than to remove.
