I actually had to buy a new dishwasher and in Germany every dishwasher has to be set to economical cleaning mode as default. That being said there is also a fast mode, but you have to use special tabs that dissolve fast enough. Otherwise they will not dissolve fully during the washing stage and then the stuff would be stuck in the dishwasher after drying and it might seriously reduce lifetime of seals etc. So be careful with short washing programs on modern dishwashers!
