Just to add some stuff.
I'm using mine for about 4 yrs by now. The dial starts spinning by it self since around 2yrs ago. Mom's margherita 2000 did the same as well to my surprise at the time.
What I usually do is to reset the computer by turning the on/off button to off position, then turning the dial to the stop position by selecting the big dot at the end of the cycle. Then, push the power button again to the on position, then let the machine run and wait until the lock warning light stop illuminating, which means the computer is resetted. Then start all over again.
Now, what causing it? I found that the machine could be overloaded. But I also experience the problem with medium load. If you have 4pairs of jeans in there, they are about 1kg each, and when you add water in the drum and the jeans soak some of the water, the weight can be doubled easily. Best suggestion is to watch carefully what's been put inside.
I've got that from my mom. She got it from one of the technician who came to service the machine for some other problem.
