John B Havertown , PA August 07, 2020 Appliance: Samsung Washer WF330ANB/XAA-00 Samsung Washer Wf330anb/Xaa-00: Washer wasn't draining. How to replace Drain Pump Assembly. No error codes showed up. After watching a few videos and taking things apart to try to diagnose, it seemed likely that the problem was the pump. I ordered the OEM from APP and it arrived within 2 days. The APP video was much better than anything else I found on line, particularly with lighting within the machine. After experience taking things apart and putting back together, the final repair took less than 1 hour. Works great again. Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
