Gasket leakes are usually from a gasket that has come loose from its mounting or maybe wasn't quite in the right place to begin with. Typically there is an inside gasket that presses against the sidewall when the slide is fully extended and another that "wipes" the edges and seals it when closed up. One or both may be out of place.
