I have a Flex Wash machine that’s probably 5 or so years old (model WV60M9900AV) and the plastic tab that clicks in and locks the inner upper door has broken off. It’s just a plastic tab with slight hook on the end and it broke clean in two. So now the upper washer cannot be run at all since it gives error code now saying the door is not securely locked.  Any thoughts on how I can fix this? Is entire door replacement needed? The tab looks integral to the assembly though I’d love to upgrade it to metal tab if possible…
