content: Seems like as long as you do only heavy loads you will be fine. perhaps allow the machine to vibrate rather than fasten it tightly.With hard drives if they arent allowed to vibrate they slow down.

content: The arrogance of "not us, we can't fail" is deadly. It was also cited the main reason of the Japanese Fukushima Nuclear accident. I made a post on that thread excerpted here:Quote from: Rick Law on August 20, 2016, 08:12:01 pm

content: I have one of these machines. There are sensors that are supposed to check when there are unbalanced loads and spin up and down the machine gradually. Basically, vibration sensors. The machine has some "jiggling" movements that it goes through to try and rebalance the load on it's own, then after it tries that out it then tests the spin up in increments. If it finds still that there is vibration, it will do some more of these "shake/jiggle" movements to try to redistribute the load. At some point, if it can't handle it, it will just shut itself down and you will hear a beep... when you manually have to move your load around and then the CONTINUE button.The problem on some of the older machines is that the support for the drum was made out of plastic. I believe it was brittle and had a tendency to snap. The new supports are stronger. But these machines have a tendency to fly around the laundry room if they are spinning and there is an unbalanced load... they will shake themselves apart. The addition of the vibration sensor is a smart move, at least it will try to correct the imbalance and then warn and stop the cycle before it ruins the machine, even if only to let you manually redistribute the load (if it can't do it through it's algorithm).Perhaps in the future the drum itself will have weights of some kind that move around the base and basically act as counter-weights. Self-balancing drum. I know from my days in the genetics laboratory that whenever we used centrifuges we had to make sure there were equal weights on opposite sides of the centrifuge holder.... otherwise you would come back to a shattered glass test tube.Here's an idea... why not over-engineer stuff? Why does everything have to be made of the cheapest thinnest crappiest materials?

content: samsung has the rep of making things that last the warranty period plus one day. bastards.I try to avoid samsung if I can.in some areas, its hard, as they have some top end products; but they still are built like crap. on purpose. money is what drives them, not quality, not pride, JUST MONEY. sad.

content: Reinventing the wheel are we?The problem has been solved for decades, a simple limit switch with a long plastic strip acting as the actuator. When the drum moves of its axis by x amount it trips the spin drive.Probably better to build in a GPS to the washing machine and if it moves out of the room turn the power offhttps://youtu.be/t2WmpsrVrTg
