At least in the US, neither dishwashers nor washing machines are typically 220VAC. I suppose if you had a commercial unit, it could be. Code usually wants the DW on a separate circuit...same with the washing machine. The DWand the WM need a drain. Most sinks are set up with a 1.25 or 1.5" drain line...WM require a 2" and an air gap into the drain line. The DW would at least need to be anchored somehow, otherwise it would tip over when you slide the baskets out to put in or take out the contents. Yes it would work if you attached a cord, but it wouldn't be right. Please rethink what you are trying to do.
