Ben R Natchitoches , LA January 02, 2022 Appliance: Model SAMSUNG WF448AAW/XAA Samsung washer would not drain Replaced the drain pump assembly. The washer/dryer was stacked in a confined space. I got help sliding the units out enough to shut off water and gas (gas dryer) and unhook all dryer connections. Took the dryer from the top of the washer and serviced the washer in place. Following instructional videos and taking my time, I changed the drain pump assembly. If I must repeat this repair, I will remove the door lock mechanism completely. After replacing the drain pump, I ran the washer through a rinse and spin cycle to test functionality. Hearing the pump engaging and the water draining was a good sign. Cleaned the area where the units stay and with help, put the dryer back in place and pushed both units back in place. I could have purchased a replacement pump for about 1/4 the cost but because of some bad reviews about the other units, I chose OEM from Appliance Parts Pros. Their delivery was prompt. It was a successful start to 2022. What else is there to do on New Years Day? 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
