Problem with polishing - briot silver plus

Hi there, After changing the mineral wheel and finishing wheel (not polishing), and after all calibration proces i have a problem with polishing. When the polishing proces start, the lens is above the wheel abaut 2mm. The most weard thing is when I start the Landing position, radius polishing rim. procedure, everything is O.K. but the value is not saving into the memory (i think). There is ofcourse questions "save parametrs" and I can save, but the adjustmets parametres are not changing. Is there any service code or some trick to modify Adjustment Parameters in this model? I'm sorry for my English but I'm not very well in writing. If someone has similar problem please write. With regards - Michael.

Ok. So now I know what is wrong. If someone will change only the finishing wheel, the diferences betwen polishing wheel and the finishing wheel will be abowe 0,2 mm, the machine will not change the parametrs. After changing also the polishing wheel everythig is o.k.
