It should be reasonable to fill the drum in the washing machine with clothes you expect it to wash. It is borderline fraud to make a washing machine that can hold 10 shirts but explodes as soon as you run it with more than 6. They have a label that says don't overload it, but without explicit markings that say a load is 6 shirts I would assume overloading meant the drum can hold 10 so don't put 14 in there. It isn't as if the user is doing something unexpected like loading it with bricks.
