.. a dishwasher tub.
We have a 2 year old Kenmore dishwasher that has been great to this point. Unfortunately, due to a design flaw, the tub has begun leaking. There is a metal brace that is screwed in underneath the tub and runs from side to side. The brace has 4 screws that screw into the plastic webbing that is part of the tub basin. One of these screws has recently punctured the bottom of the tub and it now leaks into a drain pan every time the washer is run. My initial fix, using high temp RTV gasket maker, worked for about a month and a half. I knew this wasn’t an end all fix, but I needed to try something quickly. The RTV is no longer there and I need some ideas.
I need something that can be immersed under hot water. I thought I could even epoxy a quarter size piece over the hole, as opposed to just trying to fill the hole. Please let me know of any products that will excel, or just hold up, to this type of application.
Oh yeah, the appliance only had a 12 month warrantee.
Thanks,
Ryan

Whether Vinyl, PVC, FG composite, lexaa, or other determines what glue to chemicaly weld it or whether to use an epoxy or polyester resin

Is there anything I can do to help determine the material further?

JB Weld.. 2 part epoxy...
Any other suggestions? I'm figuring I'll rough up the surface, about the size of a dime, and apply whatever is suggested. Then I will another piece pf plastic over that. Hopefully I can form a watertight sandwich and stop the leak.

Sandwich is the keyword.
Clean the tub very well to get all soap and detergent scum off the plastic. Then make up a sandwich of a couple of metal discs, drilled through the center to take a bolt. Assemble the sandwich loosely in place, then squirt a good dab of thermoplastic caulk into it and tighten down the bolt & nut with your fingers. Don't crank on it with a wrench or you'll squeeze all the caulk back out again.
It might be a good idea to use stainless hardware for this, considering the environment in which it's going to be living....
