This is a relatively new dishwasher that is starting to experience an abnormal noise; however, it does not do it consistently.
[INDENT]Here is a video of it working correctly during the wash:

And here it is with the noise:

If I open the dishwasher during the noise, it looks like the water is being properly circulated inside the tub and through all the racks.
Thanks for any advice on what part might be causing this.
