The tilt is normal and easier to unload.
The machine 'should' sense/be immune to the kind of imbalance that pinches the door gasket between the frame and outer tub. But "should" has become a VERY big word in appliance design of late.
The only way a FL can 'eat' the tub boot is destructive spin imbalance the machine 'should' have caught and responded to but didn't. In a way, that's "normal" too.
The imbalance sense is optimized for radial (deviation from drum axis centerline) imbalance. But imbalance can have an axial (front-rear) component that the sense overlooks but which bashes the tub front into the front frame. It's almost a 'freak' condition but it most assuredly happens. Mine has done it but so far I have been in the same room and shut it off before bad things happen.
I monitor any 'awkward' load at spin times. You shouldn't (there's that 'should' word again) have to do that with these "intelligent" (hah hah) machines. But then I grew up with a FL Westinghouse which MOSTLY worked but now and then went wonky and needed intervention. The Westy on the other hand, could jump 3 feet from its original position and not damage itself beyond resetting the dampers.
