If it is that intermittent all you can do is double check the perimeter seal of the vapor barrier, it doesn't take but a small passage to let water through... and the water has to trickle over that passage/hole for it to leak which could explain the intermittent part of it. Also, they have the plastic retaining clips that hold the door panel on available with foam seals around the protruding clip base to prevent water from trickling through that point as well.
