Do Bosch Dishwashers Have A Heating Element, Are They Able To Heat Dry Dishes?

I want to buy a Bosch dishwasher, but I am concerned that I have heard they are not built with a heating element. I like my dishes to dry heat, not air dried and I fear that this brand washer can not do that. In addition, if they do not have their own source of heat, what this means water used to wash the dishes does not get hotter than what comes out of your water heater? I had some difficulty getting this response from sellers of household appliances because of the brand. Thank you!
