Are you sure your numbers are right? What kind of dishwasher do you have? And what kind of oven? For the US, at least, most dishwashers are well under 1600W, and few ovens exceed under 3200W.

Yeah, 3.2 KW would mean the dishwasher's heating the dishes to high temperatures, so it'd be more of an oven than a dishwasher.

Dishwashers not only heat the water, they also heat up the entire compartment if you have the drying feature turned on. They are basically an oven.

You can cook in them as well: http://www.thekitchn.com/can-you-really-cook-salmon-in-a-dis...
