I own:
Kenmore Ultrawash Quietguard Deluxe Dishwasher
Model #: 665.13733K600

I had noticed water coming from under my Dishwasher as of late, So I pulled it out to find where the water is coming from and it looks like the molded plastic underneath the dishwasher (SEE ATTACHED PHOTOS) have some sort of rot. Water leaks out of the holes caused by the rot.
I have never seen anything like this before. Does anyone have an Idea of what this is caused by?

I am guessing my only fix would be to replace the entire tub assembly. But could I fill the holes somehow?

Thank you in advance for any help you can provide!

That is very unusual indeed, yes the only fix it to replace the dishwasher, it would cost more than its worth to just replace the tub.

There is nothing I'm aware you can patch over it to keep it from leaking when its that bad.
