I have a sigelei 150 TC I've tried tanks different rdas different settings and no matter what I do it comes up check atomizer. So I cleaned it up with 100% rubbing alcohol clean the PIN clean the rdas in the tanks still not firing. So I took it apart look to see if everything was intact look to see if there was any juice and there wasn't but still i cleaned everything inside just thorough.I check the spring put a tank on to make sure the pin was lowering down onto the spring and it did but yet it still says check atomizer. It looks like the firing pin has rounded off some not sure how but it is round and not flat. Can anyone help me out here please
