Locked In Gear Puzzle: Validator "Jammed" fails

Hi!

My solution for the puzzle “Locked In Gear” passes all tests and 6/7 validators after submitting.
The validator that fails is “Jammed”, but I can’t wrap my head around why.

Anyone that had this validator fail has any idea of what it could be?

Thanks!
