The drain pump was making a lot of noise and I kept getting Sds and F-21 errors on my Whirlpool Duet Sports washing machine. I didn't want to pay for a service tech to determine the issue so I visited the internet and did some research and verified I needed to replace the drain pump. The next issue was Whirlpool showed that the pump I needed was no longer available. I was real worried that I wouldn't find a new drain pump and would have to buy a new washer. I went to AppliancePartsPros.com and found the motor and watched the video available, which by the way was not for my drain pump style. I purchased the motor which was delivered 2 days later. I checked the new pump over and seen how the old one should come out and the new one installed. I had the new motor in and my washing machine working like new again in less than 30 minutes. This was great for me as a 56 year old woman. Easy to install and save lots of money! Thanks AppliancePartsPro!!!
