The diagnosis was a deteriorated Spider Arm Assembly on a Samsung Washing Machine, Model WF338AAB/XAA
We noticed instability during spin cycles a couple weeks prior and it progressively got worst. While still functional enough to do laundry, the vibrations just got so bad and then it happened.
Hearing words like " The machine "ATTACKED" me made me smile at first, but truth be told, this could have been very dangerous. This machine was made around 2008. It's a front loader. By comparison, the top loaders by Samsung were almost identical as far as internal parts and components. The only real difference was the orientation. And top loaders from the same time period were recalled with some owners claiming their machine actually exploded. I think recalls numbered in the millions if memory serves me.
It took about 30-40 minutes to tear it down, and I saw the pieces of the spider arm and all the debris inside the drum casing. I ordered the parts and opted for overnight shipping. I got the delivery, and jumped on it. Cannot be without a washer.
This job, although not difficult, was a time consuming process since I cleaned all parts inside and out, making the machine look new again. This put more time on re-assembly but it was so worth it. I was excited to see the spin cycle test run smoothly. I really saved a lot of money. Even today, the same machine is selling used/like new for close to $1000. I wouldn't buy it again for that price, especially due to it's obsolescence. But it is a great machine worth repairing.
When it was all said and done, I spent about $180 on the spider arm, the rear tub seal and 6 new spider arm bolts. And it ran like a champ. The toughest part was removing the drum from the struts and re-installing it again. I did it with a rope over a 4" drain pipe in the basement, and hoisted it up. This part should be done with a second set of hands but other than this, pretty easy for one man to handle hose and wire connections as well as removing related parts.
Thanks goes to Appliance Pros for having parts on hand and the speedy delivery.They have the complete tear down and rebuild video for this repair for anyone considering it. I watched it once and it spelled things out so well, I didn't even have to refer to it again. Great stuff. Truly a good experience
