How much detergent should I use in my GSD5610?

The amount of detergent depends on whether your water is hard or soft. With hard water, fill both the main cup and open cup completely. With soft water, fill both cups halfway. When using automatic dishwashing detergent tabs, simply place one tab in the main cup and close it. Only use detergent specifically made for dishwashers, such as Cascade® Automatic Dishwashing Detergent.
