How to Troubleshoot the Whirlpool GU12OOXT

The Whirlpool GU12OOXT is a residential dishwasher available online or in appliances and home retail stores. The dishwasher has upper and lower spray arms, an overfill protection float, rinse aid dispenser and a variety of tines, cup shelves and a movable utensil rack for added flexibility. The Whirlpool dishwasher is fairly easy to operate and should work well for years with only basic care and maintenance, but as with all home appliances, issues may occur. If this happens, some troubleshooting efforts may help identify and resolve the problem.

• 1

  Close the dishwasher door firmly and ensure the dishwasher is plugged in to a working power supply if it is not powering up or working. Reset circuit breakers or fuses if necessary.

• 2

  Run the hot water at the sink located near the dishwasher prior to running the dishwasher if the dishwasher seems to run for a long time. The water inside the device must heat properly before the cycle runs, and heating the water prior to washing may decrease the total heating time.

• 3

  Check the home water pressure and temperature if the dishes do not seem clean or have spots or stains after wash cycles complete. The water pressure should be between 20 and 120 lbs. per square inch, or psi, and the water temperature should be around 120 degrees Fahrenheit.

• 4

  Run a vinegar rinse in the dishwasher if dishes have a filmy appearance following cleaning. Remove all dishes and utensils from the dishwasher and place 2 cups of white vinegar in a dishwasher-safe measuring glass on the bottom rack. Run the dishwasher through a full wash cycle with an air-dry option.

• 5

  Avoid overloading the dishwasher if dishes are getting damaged, chipped or remain dirty after a wash cycle. Place delicate items on the top rack and pots, pans and other larger items on the bottom rack.
