Machines · what the machine is
A sealed pot with a valve
Of the six machines in this catalog this is the one where the gap between the description and the count is widest, because the description is short and the counts run from seven to ten across four listings from a single maker.
What the listings describe
A vessel stated in quarts, a lid, and a set of named modes that varies between listings. The words that recur are slow cook, rice, steam, saute, yogurt, keep warm, sterilizer and sous vide. Two listings state the same in-one figure and name different sets.
That is the whole of what is described. This site does not go past it.
What this site will not describe
This site gives no operating guidance for a sealed vessel of any kind. Nothing here concerns the lid, the valve, the contents, the filling, the sealing or the opening. There is no discussion of any procedure, and none of the words for working around a safety interlock appear anywhere on this site.
Every question of that shape belongs to the manual written by the maker of the specific machine, and to nobody else.
Where recalls are published
The Consumer Product Safety Commission publishes recalls and product safety warnings for consumer appliances in the United States, including this kind of machine. Its recall database is linked below. This is the only link to that agency anywhere on this site, and it is here because this is the page where it belongs.
A note on the catalog
Every electric pressure cooker in this catalog carries one brand name. That is a fact about the catalog rather than about the market, and it means this category cannot support any statement comparing makers. It is stated here, on the category index and on the home page.
What does not change when the count changes
That it is a sealed vessel. Every one of these listings states a different in-one figure or a different capacity, and none of those figures changes what the machine is. The description stops there, and so does this site.
