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?
You’re probably talking about a top loader whereas the question relates to front loaders.
Many top loaders will lock at certain points in the wash. Most often during the spin cycle. A top load with an agitator is just begging to break an impatient child’s arm.
Yeah, makes sense. They’re not very popular in Australia anymore (use way more water) so I haven’t used a top loader since the 90s. The old ones used to just slow down to a stop once you opened the lid, but they literally didn’t have a lock on the lid.
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.
