Contact during loading or washing can create a breakage risk, and stable supported placement helps keep the intended wash access. The glass must also be dishwasher suitable.
Understanding this situation
A decorative or delicate stem does not become safe merely because it fits the height. Use the model's stemware supports only within their intended arrangement, without forcing glass against the rack above.
A useful next step
Check clearance before closing the door. Handle any breakage cautiously after the machine is safe and do not search blindly for fragments. If glasses are unsuitable or cannot be positioned securely, use the maker's recommended alternative care.
