Thank you for your question on the 2730 down draft unit. The two aluminum grease filters can be washed in the dishwasher. Personally, I prefer to recommend that you wash them in the sink with hot water and Dawn dish soap. It is a good degreaser and will not harm the aluminum. Sometimes detergents available for the dishwasher mix with minerals in the water and they can fade and discolor the filters. This doesn't affect the effectiveness of the filter, but it does affect how it looks. If you do wash them in the dishwasher, make sure you use a non-phosphate detergent to prevent discoloration. This discoloration would not be covered under the warranty.
