Dishwasher on Shabbat

Question

I have been told that dishwashers on shabbat require a switch to disable the switch on the door. Otherwise closing the dishwasher door enables the mechanisim directly. Can you please explain the fine points of this matter. Thanks

Whatever you are doing is Kilachar Yad, if you're doing anything. It's also a Pesik Reisha DeLo Nicha Leih. Just ignore it. AA
