There are four important factors for getting good wash performance in all areas of your dishwasher: Loading the dishes, water temperature, detergent, rinse aid. See the below tips in these four areas to help your dishwasher perform at its best.
Loading
Top Rack
The top rack is for glasses, cups and saucers.
Cups and glasses fit best along the sides.
This is also a good place for dishwasher-safe plastics and all kinds of odd-shaped utensils.
All items should be placed facing down towards the spray arm.
Do not block the wash system parts including spray arms and towers located in the lower and/or upper racks.
Bottom Rack
Large items such as broiler pans and cookie sheets should go along the sides.
Load platters, pots and bowls along the sides, in corners, or in the back and at an angle so that water can come up, in and around them.
On most models, a wash tower rises through the center of the bottom rack during the cycle. Do not block the circular opening through which this tower rises.
Some models have a mid-level spray arm. It is important not to block this arm. Spin the spray arm before each load to make sure it is free to rotate.

Water Temperature
The water going into the dishwasher must be at least 120°F and not more than 150°F.
Letting the water run in the sink until it gets hot before you start the dishwasher will ensure you have hot water entering the dishwasher.
The water temperature can be checked with a candy or meat thermometer by turning on the faucet nearest the dishwasher. Place the thermometer in a glass and let the water run into the glass until the temperature stops rising.
Fresh Detergent
It is important to keep your detergent fresh and dry.
Discard detergent if it gets old or lumpy because old detergent may not dissolve and can leave a gritty residue.
Store the detergent in a closed container.
Do not put detergent into the dispenser until you're ready to wash dishes. It might not stay fresh or dry.
