The lid must open through its intended movement without hitting shelving or stored objects. Side ventilation clearance does not solve restricted access above it.
What the observation tells you
A partly opened lid can fall or make reaching into the cabinet awkward. Objects on overhead shelves may be knocked down during use. Removing hinge stops or changing support hardware to squeeze beneath a shelf is not an appropriate solution.
A useful next step
Check the installation and opening requirements for the model. Arrange storage or location appropriately and tell the booking team about limited overhead clearance before a visit.
