Do Frigidaire dishwashers have a filter?

I f you know your dishwasher's model number, enter it into an appliance parts website. There, you will be presented with a breakdown of all the parts on your dishwasher and you can search for "filter". If that part comes up, then yes, it has a filter. You can also search for the model number of your dishwasher for an owner's manual online. The manual will tell you if that model has a filter and whether it needs to be cleaned as part of it's regular maintenance and upkeep.
