Molly F Powell , OH September 25, 2015 Appliance: Model WF201ANW/XAA Error code nd on washing machine would not drain After 5 calls to Samsung, all ending in their insistence that we call to schedule a service appointment (that we knew would be over $250), we found this site with the part. We used YouTube to find some how-to videos, and my husband had the washing machine fixed in less than an hour! It works like a charm now! Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
