** I have an old KitchenAid KDS-15 Dishwasher and the door gasket has become hard and needs to be replaced. How do I remove it without damaging the clips **
Sorry that model is before my time but the door gasket clips used on your model look to possibly be held in place with screws? If they are, loosening the screws may be possible to remove and install the replacement gasket. You can see the gasket and clips used on your model at the link below.
