  1. Remove Lower Rack: Take out the bottom dish rack for access to the filter.
  2. Locate Filter: Find the cylindrical filter in the bottom center of the dishwasher tub.
  3. Remove Filter: Turn the filter counterclockwise and lift it out carefully.
  4. Scoop Water: Use a cup or small container to scoop out standing water from the bottom of the tub.
  5. Clean Filter: Rinse the filter under running water before replacing it.

  1. Prepare Vacuum: Set up a wet/dry vacuum for liquid pickup.
  2. Access Tub: Remove the bottom rack and filter assembly.
  3. Vacuum Water: Use the vacuum hose to remove standing water from the bottom of the dishwasher.
  4. Clean Thoroughly: Move the hose around to ensure all water is removed from corners and crevices.
