"Classixx" unfortunately is not a model no, every bosch model has classix on the front, need model no to diagnose problem. Model no is on inside of door. shot in the dark - if your machine has a filter in the door that folds open, it may have a white powder deposit partially blocking it, this can cause your prob. Test it on time dry without filter and empty, if ok get new filter.Cheers
