What You'll Need

  • Dishcloth

  • Dishwasher soap

  • 8 oz white vinegar

Follow These Steps

These steps should be performed at least once a month to keep your dishwasher running smoothly.

  1. Wipe down the interior of your dishwasher using a wet dishcloth to remove any dirt or food particles inside the dishwasher or on the inner part of the door.

  2. Fill the detergent dispenser with dishwasher soap. Turn the cutlery pad over and then run the dishwasher empty. Choose the Self Clean option if available.

  3. To remove white spots and odors, run the Self Clean option with the dishwasher empty and without detergent until it flushes. Then, interrupt the cycle and put a small mug of white vinegar into the lower basket. Close the dishwasher and let the cycle finish. For models without the Self Clean option, the Normal option can be used.

  4. Clean the filters once a month and check the nozzles if you notice a change in washing performance. Use a soft brush and water to remove any trapped particles. When removing and re-installing the filter and nozzle, make sure to refer to the user manual.
