Just a tip in case of someone have the same issue.
Since several days the sledge of my BS9000 was moving only at the slow speed so only when the lid was open.
When the lid was closed, the sledge seemed stuck and seemed hit something and was not moving.
I went into the Test Mode and ran TM n°71 and after TM n°73.
Now, my BS9000, run obsolutly fine.
