I appreciate everyone's response. I didn't think about having to strip down the machine to weld. I assume to protect the electrical components. Probably a little too much effort with unsure results. Now I feel foolish for hanging onto this for years without looking at it, I just figured the leak was a loose connection or defective replaceable part. Thanks again to everyone who replied.

Anybody want a free never used dishwasher, has a small leak? Haha
Such a waste.
