I researched the model number and several videos on YouTube. There were at least three (3) videos of Samsung customers who had taken the machine apart and found the spider was broken. They all stated that the machine was junk because replacement parts were over $500, and with labor, $800 to repair. The drive motor is warranted for 10 years, and our machine only had 2,296 cycles on it. Before throwing the machine away, I tore it apart. It wasn't too hard to get the machine apart. Most difficult part was getting the springs off that hold the tub assembly to the frame of the machine. That was a two-person job. Once I had it apart, sure enough, the spider was broken. There was a ton of liquid detergent on the back of the machine that I suspected was causing the machine to come out-of-balance. At the speed these machines rotate, any un-intended weight will cause an out-of-balance situation. I checked the bearings that are molded into the rear tub assembly, and they spun freely. Many people on-line state that you shouldn't replace the spider without replacing the bearings, which means you need to replace the entire rear tub. The rear tub is over $250, the spider $100, and the bolts $20. People on-line stated this was the advice from Samsung technical support. While I see Samsung's perspective, check the bearings yourself and decide what to do . My bearings were spinning free and the grease was still in them, so I decided to just replace the spider. The seal between the tub & spider was still good; no defect. I cleaned the entire tub with hot water and soap, cleaned up real easy. I bought some silicone lubricant and re-greased the tub bearings the best I could. I put everything back together, ran a test cycle per manual, it ran perfectly.
