Gary J Mountlake Terrace , WA November 23, 2014 Appliance: Samsung Washer WA5451ANW/XAA-0001 Samsung Washer Wa5451anw/Xaa-0001 / : Washer wouldn't drain error code nd. How to replace Washer Drain Pump. I was able to access the technical information for the washer on-line. My washer is only 2 years old so it has on-board diagnostics which let me run different tests. From the testing I determined the pump wasn't working, I removed the pump and using the part number on the pump, I was able to locate the part quickly on Appliance Pros web site. Pump arrived in two days and after installing the new pump, everything is back to normal. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
