Cheryl R Goffstown , NH January 23, 2023 Appliance: Samsung Washer WF448AAP/XAA-0000 Samsung Washer Wf448aap/Xaa-0000 / : My Samsung washing machine wasn't draining. How to replace Washer Drain Pump. First, I watched a few videos to gain the knowledge and the courage. Then, I took the machine apart, removed the drain pump and determined it wasn't working due to being bound up with sand and minerals from our hard well water throughout the 15 years of use. I replaced it with the shiny new drain pump assembly from AppliancePartsPros.com. I put the machine back together and with my fingers crossed, pressed the start button. Works perfectly! And my husband thinks I'm a ROCK STAR! Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
