Sandra J Richmond , VA September 12, 2015 Appliance: Samsung Washer WA456DRHDWR/AA-0001 Samsung Washer Wa456drhdwr/Aa-0001: Nd error code on samsung aquajet vrt smartcare. How to replace Washer Drain Pump Assembly. I ordered the part (drain pump assy) from AppliancePartsPros.com and it was delivered to my house in 2 days. I called a friend to install it for me but....he never showed up. So I decided to do it myself. I watch the video that another Appliance Part customer suggested and it was extremely easy even for a seasoned woman as myself. It only took me about 20 minutes. Test load was perfect with no errors. This morning I'm on load 5 and still no issues. Thanks Appliance Parts hopefully I won't ever need you again but if I do I will buy with confidence! 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
