Verify that the KitchenAid dishwasher is connected to a functioning power supply if it is not working. Reset the circuit breaker as needed. Ensure the drawer is closed firmly and was shut within four seconds of pressing the "Start" button to begin a wash cycle. Do not open the drawer mid-cycle, as this will cause the dishwasher to stop operating.
Run hot water at the sink closest to the dishwasher prior to starting the dishwasher if the unit seems to run for a long time. The dishwasher must heat the water at the beginning of the wash cycle, so warming the water prior to use can shorten the overall running time.
Examine the filter in the bottom of the dishwasher tub and clean as needed if the dishwasher is not draining properly. Remove large food particles from the disposer or bottom of the tub. Straighten the drain hose if necessary.
Include a rinse aid in the dishwasher if items are not fully dry at the end of the cycle. Rinse aid can be purchased at most grocery or hardware stores. Do not overfill the dishwasher, as the dishes may not dry completely if the unit is too full.
Avoid overloading the dishwasher if dishes are not completely clean after washing. Allow space between each dish and ensure the spray arms can rotate freely during use. Select a heavy soil wash cycle if dishes are heavily soiled. Use at least 1 tbsp. dish-washing detergent for each load of dishes and use fresh detergent. Detergent that is over eight months old may clump and be less effective.
Contact a service technician for assistance if the above methods do not solve the issue.
