Quoted from Ike:
Here are a couple photos showing how the ramp post will stay locked even when the end washer isn’t touching the locking mechanism. This is with the power off.[quoted image][quoted image]
I had this same issue with my LE right out of the box.
Called Stern and they sent me a brand new ramp assembly and swapped it out. Don't remember it being too difficult. Problem has never came back.
