Purchased a used Monogram Dishwasher/no factory info was included

We have a slightly used dishwasher (it looks new) that we still have not installed but would like to be sure that there was no recall on this particular model. Where is the serial number and model located?
It is a GE Monogram series with the large stainless steel front door and controls on the top of the door. When opening the door there are two thin stainless steel corner plates on the top upper insides, right and left. The only thing I could find wrong with this dishwasher is that the plate on the left side (looking into the unit) was removed and/or replaced as it has an appearance like it was crushed and reshaped to fit back in.
I'm guessing at the model number when I answer the question below, it possibly is the ZBD6880KSS, but as I mentioned earlier, I'm not sure.
