With the head screwed back onto the base, just wiggle the air tube back and forth to remove it. The flavor wicks are under that.
The Aro uses 3 1mm flavor wicks. The all need to be removed to dry burn. It does sound like a gunked coil, which won't allow proper wicking. A good dry burn will likely take care of it.
I replace the flavor wicks with cotton. I use yarn, others tease out cotton balls.
And you can replace with T3S heads
