If your automatic dishwasher isn't getting your plates, pots and pans sparkling clean anymore, try this trick before replacing it: Clean the filter inside the machine. At the bottom of your dishwasher is a filter that is designed to keep large particles of food away from the internal pump. Over time, the filter can get clogged from grease and other debris. Simply remove the filter, and give it a good scrub in the sink. When you run the dishwasher again, you may be surprised how clean your dishes will now be. As always, refer to your owner's manual for specific instructions.
