What is the primary cause of steam leaking out of the door on a convection steamer?

The primary cause of steam leaking out of the door on a convection steamer is typically a faulty door gasket. The door gasket is designed to create a seal when the door is closed, preventing steam from escaping. If the gasket is worn, damaged, or improperly installed, it will allow steam to escape, resulting in a visible leak.

While operator error might contribute to issues if the door is not closed properly or if it’s opened too often during cooking, this is not the most common cause of persistent leaking. Excessive steam pressure can lead to other operational issues, but it does not directly lead to leaks through the door itself; rather, it might cause safety relief valves to operate. The assertion that steam leaking is very rarely due to a faulty door gasket overlooks the fact that a compromised gasket is the most frequent reason for such leaks, as it directly affects the integrity of the steam chamber.
