Even if I run a load on the longest cycle, I end up with streaks on the glasses and smears of food on the plates and silverware. Is there any chance I can fix my dishwasher without having to call a repairperson? One of the most common complaints concerning dishwashers is their failure to clean adequately. If gunk and goo buildup in your dishwasher—caused by food deposits and hard water—is minor, you can often remedy the situation by running a vinegar cycle.

Simply pour three cups of white vinegar in the bottom of the empty dishwasher and select the longest cycle. The vinegar will dissolve light mineral buildup and clean gunk from the holes in the spray arm.

It will also remove residual grease from the interior walls so dishes will be cleaner and smell better. If holes in the spray arm are heavily clogged, try cleaning it manually. The spray arm is located at the bottom of the dishwasher and it typically snaps off or can be removed by loosening a screw cap. Use a toothpick to clear the holes and then rinse the spray arm under hot water.

Hot water is vital for dissolving food particles, so some dishwashers have a built-in ability to heat water to the ideal temperature. In addition, before starting a load, run the hot water in the kitchen sink for a minute to ensure that only hot water enters the machine. If the dishwasher is not cleaning dishes even after completing the troubleshooting above, the inlet valve—which allows water to flow into the dishwasher—could be failing.

A hammering noise during a cycle would indicate the problem. This rinse aid will help to prevent white spots from forming on your dishes during the final rinse cycle. You should make sure use an acidic additive, as well. One of the best options is Lemi Shine, which is a product made of all natural citrus oils that keeps hard water from causing mineral deposits from forming on your dishes or inside your dishwasher.
