David K Lake Forest , CA October 17, 2014 Appliance: Model SAMSUNG WF210ANW/XAA "nd" error on display Repair man wanted $340 to fix it. Heck with that, ordered it Thur night - shipped Friday - on my doorstep Sat. That was standard delivery too, not rushed. My son and I did the repair in under 2 hours. The hardest part was pulling the washer/dryer (stacked) unit out of the small closet in my condo. Simple to replace and worked perfectly. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
