To remove the shower screen cassette on your 2023 Wildwood van, fully extend the screen to access the cassette and track. Locate and carefully remove the mounting screws securing the cassette to the wall, supporting it as you remove the last screws to avoid damage. Also remove screws from the latch post if present. Gently lift the cassette and screen assembly away from the wall for inspection. Check the bottom seal and mounting surface for gaps, debris, or misalignment that could cause leaks. For resealing, a general bathroom-grade silicone is recommended as it performs well in high moisture environments like RV bathrooms. Applying a fresh bead of quality silicone around the cassette and shower surround will help prevent water leakage.
