Little round black thing is the sensor for zone 2 of a/c.
Carbon monoxide detector is on floor in hallway between fridge and bathroom.
As for the tank flush that is odd, did you have the tank dump valve open or closed while running it? I have always kept it open as there are several nozzles in the tank.
Never had any issues with it and works great.
