it sounds to me that althought the door is latching it is not making a good seal around the cabinet. as dishwasher cabinets are easily distorted with the door open, i would suggest that you double-check the alignment by adjusting the feet etc so that the door closes perfectly without any pulling on washtub sides. also check that your kitchen door panel is clear of the worktop and that it is not rubbing against it as you close the door.
