Getting the Best Wash Performance From Your Dishwasher

There are four important factors for good wash performance in all areas of your dishwasher: 

  1. How dishes are loaded
  2. Water temperature
  3. Detergent
  4. Rinse aids

 

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 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 entering water must be at least 120 degrees Fahrenheit and not more than 150 degrees Fahrenheit.
  • 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.
  • Let the water run in the sink until it gets hot before you start the dishwasher.

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.

Rinse Aid

 
  • Rinse aids allow water to sheet off glass and dinnerware which prevents spotting and improves overall drying performance.
