Replace the vent. Once they are good and hot they should shut. They have an expansion thing inside, also a float in case you flood the system. You might be able to disassemble it and try cleaning it with vinegar and soft brush. It would be good experience even if it is shot. You might just have a bottle like float in it. There is a liquid-vapor inside, the vapor expands, pushing out the flat bottom to close it. You can lose a lot of water with vents, besides the short cycle. When firing stops the condensation will create a vacuum that has water boiling at a lower pressure if the vents are holding it for a little while. Besides the pressure drop tripping your switch.
