Will dairy-equipment food make pareve pressure cooker become dairy?

Question:

I cooked squash on parchment on a dairy tray that hadn’t been used in a few weeks.
I want to use the squash in a soup and cook it in my pareve pressure cooker but I don’t want to make the pressure cooker stop being pareve.
Will the squash make the pressure cooker dairy?

Answer:

It may be cooked in your pressure cooker, and it will not make it cooker dairy. He reason is that although the Rema is stringent not to cook food from a milky pot in other pots, that is only if the pot was used within the last 24 hours. In your case it wasn’t, therefore it is permitted.
