With any dishwasher, you’ll get better performance if you load the dishes correctly, use a dishwasher detergent with enzymes and use a rinse aid. You should also consult the user manual for guidelines on loading your machine most efficiently. It is important not to let dishes or utensil nest or rest side by side, which can prevent water from reaching all surfaces. To prevent chipping, make sure that china, crystal and stemware don’t touch other items.
You might find this impossible, but most machines now do a fine job if you don’t pre-rinse dishes, so skip the sink. You’ll save about 6,500 gallons of water a year(based on average household usage). You can further save water by running only on full loads. If leaving dirty dishes unwashed does not sound appealing to you, you can run the rinse cycle which uses about 2 gallons of water – much less used than by hand-rinsing under running water.
A rinse aid will help minimize spotting and a detergent with enzymes is good in dissolving starches and proteins, so opt for this type of detergent and have a rinse aid handy.
