I have the same 2016 230 BHXL and it is a Schwintek slide. The first thing to try is their is a manual over-ride on that control box under the slide. I am pretty sure I have posted some links previously that I will have to see if I can dig up, but I can say even without posting those there is a wealth of info on the Schwintek system on YouTube.
Couple other things to note. I can't remember for sure, but the fuse for this might be on the panel under the front of the bottom bunk so you may want to check that. Worst case if you need to manually push out the slide that involves having to slide down the bulb seal and remove a screw for the motor and then sliding the motor down to disengage it from the rail.
