How to Check the Balls in a Frigidaire Pump

The drain check ball is a plastic white ball in a Frigidaire drain pump filter assembly that helps prevent debris from entering the dishwasher. If the check ball moves out of position it can cause a loud clicking sound in the pump. Also, you may have a cracked check ball that needs to be replaced if your dishes aren't being thoroughly cleaned. Once you've taken the entire drain pump out of the dishwasher, you can remove the check ball.
