Open the Asko dishwasher and slide the bottom dish rack from the tub to expose the bottom of the appliance.
Look for the filters in the floor of the wash tub between the door and the spray arm. The Asko dishwasher has three filters: a coarse filter located in the center of the large, oval-shaped main filter and a fine filter beneath the coarse filter.
Look for the two tabs along the edge of the center coarse filter. Use your fingers to squeeze the two tabs toward the center of the filter and lift it from the bottom of the wash tub to expose the fine filter.
Rotate the fine filter counterclockwise and lift it from the bottom of the dishwasher.
