Use a citric acid dishwashing cleaner, available at most grocery stores or drugstores, if a white film is apparent on dishes or inside the dishwasher.
Check the water pressure to the dishwasher if the dishwasher does not seem to be performing well. The water pressure should be between 20 and 120 PSI. In addition, ensure the proper wash cycle is selected for the dishes that are being cleaned. Heavy soiled dishes should be washed in a "Normal" or "Heavy" wash cycle.
Wipe the bottom of the dishwasher if bad odors emanate from the dishwasher. There may be food particles stuck on the bottom of the dishwasher, causing the odor. Check the pump inlet in the back, right-hand side of the bottom of the dishwasher and remove any debris that may be blocking the inlet. Use a paper clip to remove any debris that may be blocking the water jets.
Turn the power off at the circuit breaker for 30 seconds and then reset the dishwasher if the error codes "C1" through "C7" appear on the console.
Empty the lower rack first if dishes are still wet after the dishwasher has completed the wash and dry cycle. Ensure dishes are not touching when placed in the dishwasher and avoid overloading the dishwasher.
Ensure the dishwasher is turned "On" and the door is latched firmly if the dishwasher does not run. The power cord should be plugged firmly into the power outlet and the dishwasher.
