I have the same issue with my 2018 Windsport 29m. Curious if you found out a solution. Have mine going into the shop on Monday, but have checked fluid level and all fittings. Drove it home from the dealer fine, and then two days later went to drive it and it was complaining about the leveler retract. Did reset and didn't work. Hopefully the shop will be able to tell me something as I haven't even been out in it yet.
