Not much help from me on the error codes but let me introduce you to a tub full of info on the RV!
One of the things I like about the Winnebago line is that they seem to try to help keep them running with info online!
A great place to find what's in the new Rv is the interactive parts catalog here:
https://catalog3d.winnebagoind.com/menu/Parts.htm
Drill down to your RV, then "exterior" and finally choose which slide!
Or for more fun, you can wander around finding all kinds of things if it happens to be a good day for resting?
It takes a bit of play to get the controls to work but it is amazing how much detail you can drag out!
Click these snips for better view!
I picked left front but yu may need a different slide?
Turning it over and around we get a look at an electric slide using a motor instead of hydraulic rams! Click on the item you see to highlight in yellow and on the list OR the opposite if you know the name but not location!
Clcik it repeatedly on the list and it "flashes" in yellow on the drawing to help spot things! Handy when we find something and need to know WHAT we found?
In this case if you want more info on the slide mechanics, break it down to itemized parts.
You should find an electric motor?
Maybe it has just come unplugged??
Best of luck in the search and yell if you need a hint on the controls.
One of the big ones is down in lower left corner. Before zooming, etc. and if you want to keep a spot centered, hit the + sign and then click a part on the drawing. That lets you scroll to zoom or click and drag the mouse to move it around.
