All American question
    #7960112 - 01/31/08 01:05 PM (16 years, 1 day ago)

Hello all,
I recently bought a new All American pressure cooker, model #941.
Today I tested it for the first time, but I don't know if it's working as it should...
I've set the pressure regulator weight at 15 lbs, but the pressure won't go higher than 13,5 PSI (that's what I read on the pressure gauge). It should be going over 15 for proper sterilisation.
Even if I keep the heat up to the highest level, the pressure stays at 13,5 PSI and steam constantly keeps coming out of the automatic pressure control.

Is this normal? Can I change this and reach 15 PSI or more?
Thanks, rrotto

Yeah, it's normal. Mine does that too.

You do not want steam to escape constantly, read your manual well brother.

Your gage, or weight is slightly off.

READ YOUR MANUAL!

PCs can be dangerous if used improperly.

The weight should NEVER float continuously, NEVER.

Adjust your stove so that the weight lets out a bust of steam no more than 4-5 times per hour.

Maintain that temp for 90-120 minuts.

Strange! I don't mean ask silly questions, but did you Thoroughly read the owner's manual? There might be something that you missed. I don't own an All American, but it almost sounds like you're missing a weight. That or you're losing pressure around the seal. My owner's manual had me wash and oil the lid seal prior to first use. I also had to do that for my emergency pressure release gismo. Could be something simple as that. By the way, there has to be something wrong because you shouldn't have the heat all the way on high. Once the rocker starts to move, you bring the heat down to about 6 or 7 on an electric stove. You just want that steam release barely coming out.

Yeah, and run petro jelly around the bottom rim where the lid seals, and add a splash of vinegar every time you change the water out.

My 15 psi weight floats when my gage is at 14, so I just adjust the heat so it almost never steams more than 3-5 times per hour.

If the weight rattles constantly, TURN the heat down.

I don't let the heat up all the time. I just tried that to see if anything changes, but when I do that the pressure stays the same. The only thing that changes is that the weight rattles constantly.
But offcourse when it does that, I lower the heat a little so it only rattles 2 times per minute or so (you don't really mean per hour do you?).
I must confess that I tried holding down the weight with a spoon a little while to avoid steam release. That way the pressure reached 15 PSI after a minute. But that was just an experiment. :cool:

I lubricated the seal with vaseline before use and there is no leak of steam anywhere but at the pressure regulator.

So do you think the gauge is slightly off and is the actual pressure 15 PSI when it says 13,5?
Or should the weight not be heavy enough?

Yes, and no, try another weight, but I am sure it's fine, 13.5 for 2 hours will do the job either way, though I'll bet you are at 15.

That's the same one I own, and it rocks man, but take care of it.

Wrap your jar lids in foil, to avoid rust spots on the inside, the vinegar will help with pitting.

I never thought to calibrate mine, cause at 14, thats plenty, trust me, but I think you could get the gage calibrated.

Hmm, i have a Presto brand PC. I've always taken the PSI to 15 and the weight is spittin and sputtering like crazy.
I bought it on ebay and it came with no manuals.

Does the weight on these PCs work the same way?
Is it dangerous for that lil rocker to be hissing like 60 times a minute?:confused:

Don't let the weight float the whole time, its not good for the PC cause it lets all your water out, which will dry your grains also, and risk ruining your PC if the water escapes completely.

It should hiss no more than 4-5 times per minute IMHO, and All Americans.

I've been testing the PC another time. Here are the results...

I'm using an electric stove with settings 0-0,5-1-1,5-2-2,5-3.
* If heat is turned to maximum (3): weight jiggles constantly and pressure on the gauge is 13,5 to almost 14.
* If heat turned down to 2,5: weight jiggles almost all the time, but not constantly. Pressure is 13,5.
* If heat turned down to 2: weight does not seem to jiggle at all. Pressure has dropped to 12.

So I suppose it's better to keep the heat on 2,5, even if it jiggles a lot?

I fill the pc with 3 liters (=quarts) of water, to be sure it won't cook dry...

Is it a bad idea to add a little weight on the regulator weight, so it would only jiggle from 15 PSI...?

Yes, sounds bad to me man, they are rated for 15 max, and most have a pressure release at 18, but if it doesn't, it could theoretically explode.

13-14.5 is fine, it's not that accurate, it's a gage, a rough estimate, it is not perfect at all.

But if your gage reads 14, and the weight hisses 4 or 5 times per minute, you will be fine.

this is big. I do not know where I missed this and I would have to crank down on the nuts until i put some carmex on it. Now its just 1/2 turn past contact with the lid.

If the weight was bouncing then I wouldn't look at the gauge. Hell my gauge reads 3psi when its not on. There are some screws on the back and i assume you can calibrate it.

Some stoves do not produce enough btu's to get it to 15 psi. keep that in mind.

i believe you can remove the weight assembly and put a stopcock and bring it up to 20psi safely but it will not jiggle so you have to watch it closely. i believe the plug is set to blow at 20+psi. It is highly unlikely that the pc will blow up, they try to make them idiot proof but we all know this in impossible

I wouldn't want to be around when a plug blows.

A rubber bullet bouncing around the kitchen plus hot steam everywhere.

10 times better than an explosion but still scary as hell.

Ok so I assume it's the gauge that isn't accurate as it should.
What's the point of a gauge when it does not tell the exact pressure...?
So it's just an estimate....

When the PC is not in use, should the gauge point at 0? Mine is below 0.

Which means when the PC is at 15, it will read below 15. If it's important to you, you can probably report the problem to AA and they'll send you a new gauge.

When pressure is reached, turn down the stove to the minimum setting that will maintain pressure. I don't allow the weight to rattle at all. Doing so is only releasing your water inside as steam. You'll hear a slight hiss before the weight rattles. Find the sweet spot on your stove setting that will keep it hissing, but not rattling the weight.
