If you’re noticing a bad smell coming from your dishwasher or are seeing food particles on your dishes after the dishwasher has run, it might be time to clean the filter. Fortunately, cleaning the filter takes no more than a few minutes and involves just soap and water. Once you determine where the filter is, you can remove it piece-by-piece, clean it, and put it back. At that point, your dishwasher will start working normally again!

If you see a series of holes or plastic grid at the base of your machine, you have a self-cleaning filter.
