Combine potatoes, onion and ham in a lightly greased stoneware Crockpot.
Combine gravy mix, mushroom soup and water; whisk until combined. Pour gravy mixture over potatoes. Cover and cook on low 7 to 9 hours. (High 3 to 4 hours). Top with cheese during last 30 minutes of cooking.
NOTE: To prevent darkening, toss sliced, uncooked potatoes in a mixture of 1 cup water and 1/2 teaspoon cream of tartar; drain and proceed with recipe.
