Dustin B Paragould , AR July 13, 2015 Appliance: Samsung Washer WF350ANW/XAA Samsung Washer Wf350anw/Xaa / : Kept getting error code "nd" for no drain. How to replace Drain Pump Assembly. Take drain cover off of front lower right corner, remove grey insert (2 screws) from drain access. (remove this only so you can see what your doing.) Tip the washer on its back and remove 2 bolts from the pump and it comes out through this hole on the bottom side!!! Watch these edges they are very sharp!!! I had an issue with a leak due to not having a hose clamp seated correctly, other than that takes less than 30 minutes and fixed our problem. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
