Most washing machines have a timer that prevents you from opening the hatch just after the washing cycle ends. Instad you must wait for the timer to go off, usually a minute or two, before you can open the hatch.
Why? Would letting the user open the hatch immediately after washing ends pose any safety or other issues?
There are high efficiency top loaders too. I have an old style one because I couldn’t afford to keep repairing my HE, and 400 for a new top loader was cheaper than replacing the motherboard in my HE for the 3rd time.
