Cleaning your filter

Your dishwasher's triple filtration system minimizes sound, optimizes water and energy conservation, while providing superior cleaning performance. Throughout the life of your dishwasher, the filter will require maintenance to sustain peak cleaning performance.

The triple filter system consists of 2 parts, an upper filter assembly, and a lower filter.

  1. The upper filter assembly keeps oversized items, foreign objects, and very fine food particles out of the pump.
  2. The lower filter keeps food from being recirculated onto your dish load. The filters may need to be cleaned when:
  • Visible objects or soils are on the Upper Filter Assembly.
  • There is degradation in cleaning performance (that is, soils still present on dishes).
  • Dishes feel gritty to the touch.

It is simple to remove and maintain the filters. The chart below shows the recommended cleaning frequency.

Very Hard Water

If you have hard water (above 15 grains), clean your filter at least once per month. Building up of white residue on your dishwasher indicates hard water. For tips on removing spots and stains, see the "Troubleshooting" section in your Owner's Manual.                        

Filter Removal Instructions

  1. If the water filter area (bottom of the dishwasher) gets larger food particles or foreign objects (toothpicks, broken glass, olive pits, etc.) around it, they should be carefully removed by hand and discarded before removing the filters. If foreign objects drop into the filter area, the dishwasher could have further issues.
  2. Turn the Upper Filter Assembly ¼ turn counterclockwise and lift out.  Note that you may have to move the spray arm to remove the filter, especially if you have the X style shown above.

Cleaning Instructions

IMPORTANT: Do not use a wire brush, scouring pad, etc. as they may damage the filters. Rinse filter under running water until most soils are removed. If you have hard-to-remove soils or calcium deposits from hard water, a soft brush may be required.

Filter Reinstallation Instructions

  1. Please note the previous illustrations, place the lower filter under the locating tabs in the bottom of the dishwasher, so the round opening for the upper filter assembly lines up with the circular opening in the bottom of the tub.
  2. Insert the upper filter assembly into the circular opening in the lower filter.  
  3. Slowly rotate the filter clockwise until it drops into place. Continue to rotate until the filter is locked into place. If the filter is not fully seated (still turns freely), continue to turn the filter clockwise until it drops and locks into place.

NOTE: The upper filter assembly arrow does not have to align with the arrow in the lower filter as long as the filter is locked.

IMPORTANT: To avoid damage to the dishwasher, do not operate your dishwasher without the filters properly installed. Be sure the lower filter is securely in place, and the upper filter assembly is locked into place. If the top filter assembly turns freely, it is not locked into place.
