Most washing machine doors are hinged on the left. The door closes into a catch on the right. Some people find they need the door to open on the other side. The only washing machines I’m aware of that have the door hinge on the right are Miele washing machines Plus the Hotpoint Aqualtis range appears to be hinged on the right. The Aqualtis range is the washer with the very large door incorporating the control panel.
If you have a built in washing machine with a cupboard door that attaches to the washing machine’s door you can usually choose which side to have the door hinge on. But you can’t change the door hinge around on a freestanding washing machine.
The vast majority of washing machines have left hinged doors. They cannot be changed around. I can’t think of a logical reason why they are hinged like that but they are.
