Amos V Sweet Valley , PA October 24, 2015 Appliance: Model WF419AAU/XAA 03 Noisy samsung vrt washer gives "nd" code on display with water in tub Drained washer tub from lower bypass hose. Checked filter slot for debris. Cycled 2 more times with same outcome, "ND" not draining. Dirty clothes being held captive as door won't unlock. Found site online with Samsung customers with same issues on 4-5 yr old washers. Deductive reasoning indicates bad washer drain pump. Ordered part from Appliancepartspros.com, which was very reasonably priced. Arrived 2 days later (no upgraded S&H). Found video on YouTube and followed instructions. Part was a perfect match. Removal and installation took 28 mins total. Very easy to change. Washer is much quieter now. Wife Happy too.. : ) 32 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
