If you haven’t watched technology connections on dishwashers, you should use powder or liquid detergent, not pods. The pods don’t add anything to the pre rinse cycle. You should also run your tap on hot until hot water comes out before you start the dishwasher. The pre-rinse cycle uses very little water and the dishwasher is connected to the hot water supply on your sink. It might not actually get hot water at all if you don’t.
