I'll start from the beginning: 
I bought the Kanger AeroTank last night (with a colored glass and different tip) and as of last night, it worked perfectly. Come to find out, the liquid I used was a custom mix I chose at the shop (peach and honeysuckle), but ended up not tasting very good. I poured the bulk of the liquid back into the bottle (from the bottom, of course). And then proceeded to take the tank completely apart to clean it. I cleaned every part EXCEPT the cartomizer and the metal ring that was attached (the air hole part), just ran water over the parts to get the juice off. Now I put it back together with different juice and it's not functioning. I push the button and I hear no bubbling/crackling and it does not work at all. What are some things that could be wrong that I need to check? Or did I do something wrong last night while cleaning?
