I could not open your photo but my guess would be to locate the water strainer that goes between the tank and the pump. It should be clear plastic, round, about 3" in diameter and readily accessible for cleaning. Then follow this hose to the pump which should be nearby. Also check your owners manual, there is usually a diagram showing item locations. Hope this helps. Capt. George
