This is caused by the liquid contaminating the inhalation sensor. I had the same problem, I took the equipment apart and cleaned the rubber band that is located there. Unfortunately this was not enough, so in my case the workaround for the problem was to remove this sensor completely and smoke only from the button. In addition, I sealed the hole from the sensor with hot glue so that the liquid would not run inside.
