said by KrK:No washer should be destroyed or heavily damaged because items that commonly end up in a washer (like coins or buttons) do accidentally end up in the machine.
That's just a serious design flaw. Manufacturer should have to recall and fix or replace the washers for free.
At my house now and when I was growing up the checking of pockets and removing anything in them was part of the washing procedure. Neither my mom's or my washers have ever experienced any damage from objects left in pockets and no we never dug out any coins or other metal objects that didn't cause damage.
I don't see how it's a design flaw when objects other than clothing are placed in the machine.
