While the exact appearance of the filter will depend on your dishwasher brand, it often consists of a cylindrical or rectangular mesh or plastic component. The filter is located at the bottom of the dishwasher beneath the lower spray arm. It includes a combination of a coarse filter, which traps larger food particles, and a finer filter, which captures smaller debris. The filter assembly may be a single unit or a multi-part system that can be twisted or snapped out for cleaning.

To clean an old dishwasher without a filter, start by removing the bottom rack to access the drain area. Use a damp cloth or sponge to wipe down the interior, paying special attention to the corners and crevices where food particles and debris can build up. Pour a cup of white vinegar into a dishwasher-safe bowl and place it on the top rack, then run a hot water cycle to help break down grease and grime. After the cycle, sprinkle a cup of baking soda across the bottom of the dishwasher and run a short hot water cycle to deodorize and further clean the interior. 

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Dishwashers should be cleaned a minimum of once every 3 months, but really it should be done monthly. This is to prevent germ buildup and will help keep your machine running smoothly. Dishwasher maintenance isn’t too difficult, you’ll simply clean the filter, wipe down the spray arms with vinegar or rubbing alcohol, and run the cycle on empty. If there is any debris, you can remove it with a small metal pick. Do not use wood as the tip can break off inside the machine.
