Taking apart the inside of the dishwasher to find the part did not help in my case because the problem was that a piece of the food chopper blade came off and was getting knocked around by the chopper blade. I found this by pulling the dishwasher out and carefully tipping it on it back.
I would recommend cutting the power to the dishwasher first and then removing the electrical cable/box at the base.
Then I carefully disconnected the electrical cable from the housing of the chopper blade. This was on the bottom of the dishwasher (on the outside). I unscrewed the housing of the chopper blade and found that a fin of the chopper blade had broken off.
A new chopper blade was all I needed to fix this issue. Dishwasher has been working great ever since. I would say that this was not a super easy fix, but anyone could do it with a little research.
