If your dishwasher is leaking- you are probably giving your wife too much to drink.
Seriously, IIRC Concept II was GE's entry level model in the 90's. So as Incinerator pointed out, it may be smarter to replace it rather than getting it repaired.
If you are going the replace route, and want a contact at the Brick's comercial sales dept, fire me off a PM. He can probably get you a few bucks off a new one; or sometimes with dishwashers they have "builder" models that are scaled back but do the basic job.
