Frigidaire Dishwasher FFCD2413US3A banging noise while switching between spray arms

Hi Everyone,

I have moved into a house few months back where we have this very cheap dishwasher already installed by the builder around 2 years back. I have very limited experience with dishwashers since this is my first house after moving to Canada. I think the wash cycle sounds like it switches between upper and lower spray arms every minute or so. The problem is that whenever it switches the cycle, it makes this loud banging noise. During the first 15-20 minutes the banging is very faint but as the washing progresses it gets louder and is sometimes followed by a loud grinding noise as well like slipping of gears. It has been doing this for the past 7-8 months ever since I have moved in with no signs of further wear or breakdown. Please see this video at the link below, the switching happens at 18 seconds mark during which you can hear that noise. Any help would be really appreciated.


You have a check ball in the sump that makes the water flow to the spray arms, make sure that ball is moving freely. The small pauses make that check ball move back or both for each pause to send water to each spray arm.

Here's the video to access the check ball:

Let us know what you find.

Thanks for the reply Jake. It was indeed the check ball that was making the noise. I have tested by removing the ball and running the dishwasher which eliminated the noise completely. The problem is that there seems to be nothing wrong with the ball itself and it seems intact and in proper shape. Now the question is why does it start sticking half way through the wash cycle, could or be due to hot water or the detergent? I have read somewhere that using Finish brand detergent eliminates issues with check balls.
Those are good questions but I really don't know the answer, as I have not run into this problem as of yet on my local customers.
