I should clarify a little more. When I said to just push 'the bottom part' of the Sofia out of the tank, I should have said, first close the juice control (so O-rings aren't damaged) and then 'push the whole Sofia downward' until just the bottom part is showing outside, then unscrew that part from the Sofia and work on the coil. I had made it sound like you could just push the 'bottom part' of the Sofia but no, the whole Sofia gets pushed down after you close the juice control, you just stop pushing the Sofia when that that bottom part with the coil is outside the tank.
