To solve this, I did some internet sleuthing on the symptom (tub not spinning during the spin cycle), got a decent idea of what a few of the possibilities might be, then headed to AppliancePartsPros.com website. They make it very easy to find the part(s) you're looking for by using the exploded view drawing. I looked up the two different part possibilities (driver coupling and clutch) and watched the video they provided for each on how to fix. The videos are great and super helpful. They are well done and thought out for novice appliance repair people like myself. No handheld jerky videos like on YouTube. The technician in the video confirmed why you might need to replace each of these two parts by describing the problem experienced. I consider myself mechanically inclined and able to fix a lot of things, but would not have been able to change out the clutch mechanism (my particular problem) if it were not for the great videos on this website. I watched the video several times during the repair to make sure I was following all the necessary steps. I ordered both parts just to make sure I covered the bases since we needed our washer back in business ASAP (two teenage daughters). Once I got the parts, I took my machine apart and found the driver coupling was fine. I replaced this part anyway since the washer is 10 years old. The clutch mechanism was the culprit, so it was replaced. My washer is fixed. I think it actual sounds a bit quieter now when running. Why pay some repair company several hundred dollars for something you can do yourself with the help of this company. Great videos on how to repair along with easy and fast ordering, long time loyal customer. Well done!!
