I ordered a Bosch Dishwasher 800 series and they wanted me to pay $200 to install, so I declined. I finally got to install over the weekend and do it myself.
I made the connections and pushed the DW into the enclosure. I had to pull it out and from the left side, a plastic piece popped out. Now I looked everywhere and I cannot figure out where that part goes. it seems to be a sort of cover for some wires.
How do I figure this out? I completed the install and it's working well.

Here's the part:

Until someone comes up with a great answer,
here's where we all go to figure out such DIY things

Put the model # in https://www.bosch-home.com/us/owner-support/cleaners-accessories/spare-parts and then browse the parts diagrams. Looks like it may have popped off the bottom based on the random 800 series model I entered.

Thanks guys, I will try it out.

Mine popped out too.
It covers the wires above the white hose.
Dishwasher will likely work a long time without it.
