How to fix most common problems with the Wismec Reuleaux 300 & TFV12 Atomizer RBA Dual Velocity Deck If newcomers to this thread is confused. This is the thread where i had the problem. Here i have made a guide that you can follow in order to fix the problems you have with the Tfv12 RBA. I had many different problems with my setup and it took me alot of time to find out of these issues. These are steps you should follow even if you dont have the related issue. Make sure you start from the beginning and work your way down. PROBLEMS I HAD AS I VAPED: Dry hits, burnt taste, high noise when firing. Quick response when firing. Also leaking. Atomizer shortage, battery disconnections and coil heating only from the holes. Unstable Ohm readings Problems and how to solve: 1: Battery pins has been dirty Symptoms: Unstable Power, noisy firing, quick fire and battery disconnections. Also possible burnt hits. Solution: Clean the pins with cloth, clean until the dirty marks are off. You can take out the batteries and clean them to. 2: Battery cover has been to loose Symptoms: Unstable Power, noisy firing, quick fire and battery disconnections. Also possible burnt hits. Solution: Use your thumbs and press as hard as u can against the battery cover multiple times. Your battery cover is tight when you can push it up without seeing the batteries loosing connection (from the display) 3: Coils have been too close to the cap Symptoms: Atomizer shortage Solution: Move both coils closer to the center, make sure they are not touching anything! 4: Wismec RX 300 is reading more than .10 ohms wrong That is a FACT! 5: Screws for the coils are not tight enough Symptoms: Coils are not glowing properly, coils only glow from the holes. Can cause dry hits, burnt hits, more unaccurate ohm reading. Solution: Avoid the umbraco coming with the RBA kit and buy a pack of coils and use their umbraco instead. Tighten them as good as you can. Also make sure that the coils dont go out on the other side of the holes. 6: Way to tight wicking, no proper technique Symptoms: Dry hits, burnt hits, leaking. Solution: Liquid has been pulled upwards instead of (side upwards). Move the wicks to the side and stroke them then carefully pull them down. Use tweezers. Also make sure that you have primed it, also put some juice at the top of the coils, wait a little until its saturated and repeat 2 more times. Leaking issue happens if you have used to little wick. Much of the wicking process is about positioning, patience and using the proper amount of wick. Better use more wick than less! Learn the scottish roll technique Took me a total of 6 days to find out these issues and making it work properly again. I hope experienced users and beginners can now save some time I hope this helps to everyone that have the same setup as i have. I also recommend wismec users to update the firmware. Problem SOLVED !!! Thanks to everyone in the forum that came with troubleshooting tips and all the engagement. My life is saved, and happy vaping to all!! Vape ON!!
