Hey! Thanks for reaching out, can I get you to send me a private message with your model number and serial number?
I got a Samsung and I have had trouble with it since they installed it too! It takes FOREVER and wastes so much water continuously rinsing over and over and then I can't even open the lid if I want my clothes out because it won't finish I hate it! I wish I bought a simple washing machine and I would have save so much time on top of money
I read through 14 pages of the community forum on this very topic. A couple of people suggested that there was some wiring loose. Maybe. Our washer is a top loader, model WA45H7200A, has been used for 2 years, but it is out of warranty, of course.
The fix that our handyman friend discovered was: https://www.youtube.com/watch?v=25kVSQqNq2Q
The springs were simply too weak to take on the spin cycle when there was > 1 laundry basket of clothes. Empty or very small handwashing-size loads, it was totally fine, but 1 laundry basket full, or bath towels, forget-about-it. Supposedly, you can buy new springs (for some models, but possibly not all) for around $70. Our handyman friend put some old hose around the springs to make them stiffer and give them support, and now the washing machine actually is VRT, as claimed by Samsung's marketing dept.
Hope this video will help others, as Samsung customer service has not been forthcoming about this very common issue. I don't agree with paying a Samsung technician $400 for a non-guaranteed service call for a $700 machine that is pretty new. Good luck.
