How often should I clean the dishwasher filters?

Filter cleaning frequency depends on your usage habits and water hardness. If you rinse dishes before loading, clean the filter 3–6 times a year; if you only scrape before loading, clean it 4–12 times a year; and if you have hard water, clean it 12 times a year. Always clean the filter after washing loads with large amounts of food soils or heavy starch content like potatoes and pasta.
