Here we go for all the do it your selfers, Tools needed- Super tiny screwdriver or allen wrench, lighter, long pair of tweezers and a steady hand.
1, take out screws
2, gently pry up (evenly) the core and pull out straight
3, you might have the wafer stuck to the core so watch out, you will notice build up around the core
4, burn off the wafer and wash, repeat if necessary. it should almost turn completely white.
5, burn off the core, wash and repeat.
6, take out the battery in the cera and gently screw in the core but not all the way so it wont get stuck
7, after a couple 20-20-20 burns it should start to turn bright red and glow. let cool completely
8, take out battery and unscrew the core. now gently pick away at the carbon buildup but not the ceramic. depending on how bad the clogged ceramic you might have to do a ISO soak and rinse and burn just to get all the gunk out.
9, it should start to turn white but probably not completely. When you go to put it back together make sure everything is cool to the touch that way things wont be expanded by the heat.
10, reverse procedure for putting it back together but DO NOT over tighten the screws. That's it you have a like new cera and you now understand how it works. Totally love mine and I use it exclusively for my meds, but it is flawed by design imo because it seems like that particular piece is designed to be thrown away and replaced which I do not like. Peace
