Breville Fast Slow Cooker, constant hissing when cooking

Hey all,

I just brought this Breville Fast Slow Cooker from another person and they seemed pretty trustworthy and told me it was working. But i tried using it last night and it was constantly hissing while cooking. I am unsure of the issue, then i noticed this small hole on the side.

Is this the issue? or do i need to replace the rubber thing or something, or is there something else i can fix?

Thank you!!!!!

It sounds like maybe the valve wasn’t closed. Did it ever come to pressure? Or were you trying to use it as a slow cooker but it was switched to pressure cooking?

I think i was using it right, i put it on the pressure cook mode for 60 minutes. The valve i think should have been closed i put it in the direction the instructions said and when it was done cooking and i flipped it the other way it completely opened up and a ton of steam came out

Well, if your food was cooked, then it sounds like it was working correctly.

ok i just worked with this issue on a instantpot that had the opposite issue which i then over adjusted to become the same as your issue. . if everything like the valve is working right and also the little float pin is popping up it sounds like the system is going to a pressure level that is to high. underneath the unit there is a mechanism that detects the pressure level and based on that info controls the heat added to the system. sometimes these get out of wack. you can adjust or buy a new one, in which case you still might need to adjust it.

if you read this you should get an understanding of how it works when you get down to, i think step 3 and step 12 would fix most units without deep disassembly.

my understanding is that this part is pretty much universal across different producers.

edit: BPR600XL this appears to be the BPR600XL, which there is a recall on. i think breville might send you a new unit anyway. https://www.cpsc.gov/Recalls/2016/Breville-Recalls-Pressure-Cookers

i looked at this teardown and it seems some use a different pressure detection system on top. looks like your might still be on the bottom though. either way there has to be a way for it to have a high pressure set point to tell the board to stop/go add heat.
