Sarah W Waldorf , MD February 02, 2019 Appliance: Samsung Washer WF448AAW/XAA Samsung Washer Wf448aaw/Xaa / : Not draining halfway through cycle and grinding noises. How to replace Washer Drain Pump. No ‘ND’code displayed but did say check filter. After awhile I ordered the new drain pump. I took apart my washer, cleaned pipes and drains (watched YouTube). Once the new pump arrived, I replaced that and put it all together. It was actually all pretty easy and now the washer drains and does not make any grinding noises!
