Check the water pressure.
• The water pressure to the dishwasher should be 20 – 120 PSI (3/8″ O.D. copper water line or 1/2″ O.D. plastic water line).
Check the wash cycle selection.
• Select the appropriate cycle for the dish load. Selecting a short or light wash cycle may save water and energy, but may not provide proper wash action for a heavily soiled load. If food soils remain on the dishware after the cycle, a longer cycle may be required. Please consult the Owner’s Manual.
Check the water temperature.
• Proper water temperature is essential to achieve optimum results from your dishwasher and the detergent. Hot water is needed to dissolve and activate the detergent so that it can loosen and remove common food soils.
The hot water heater should be set to deliver at least 120 degree Fahrenheit water to the dishwasher.
• To check the water temperature, run the hot water at the kitchen sink and measure the temperature of the running water with a candy or meat thermometer. Adjust the temperature of the water heater accordingly.
Be sure that the dishwasher is filling with the hottest possible water.
• Run the hot water faucet at the kitchen sink prior to operating the dishwasher. Also, avoid running the dishwasher while hot water is being used for other activities.
Check the amount of detergent and the water hardness.
• The amount of detergent needed depends upon: water hardness, the amount of food soils left on the dish load, and the temperature of the water going into the dishwasher.
Use a rinse agent.
• Rinse agents promote wash and dry performance by causing the water to sheet off of the ware inside the dishwasher. This prevents water spots from forming on the glassware and dishware.
Check the dishwasher loading.
• Make sure dishes are loaded properly to insure that water can reach all of the soiled surfaces in both racks. Please consult the Owner’s Manual for proper loading patterns for your specific dishwasher model.
Excessive amounts of food may clog the dishwasher filters and reduce wash performance.
• In models without extending wash towers, the spray arm may be removed to check the fine filter underneath. Gently lift up the spray arm while rotating it counter clockwise about 90 degrees. This will “unscrew” the arm and permit its removal.
Inspect the fine filter. It should be clean.
• If the fine filter is not clean, contact our service department. To prevent this from happening, scrape dishes before placing them in the dishwasher. It is not necessary to pre-wash your dishes, just scrape off the big chunks.
