how to disarm a potentially pressurized whipping siphon?
My situation is much like spongefile's:
- I'm using my iSi cream whipper for the first time, charging it as instructed out of sweat-deserving fear of pressurized items
- Nothing is released when I push the lever, regardless of orientation, not even dripping liquid
Some differences:
- the contents of the whipper are blended pressure-cooked beans whipped with 35% whipping cream + 3 iSi cartridges
- when I charged the cartridges, leakage happened around the charge holder and some of the bean preparation leaked from around the device head
- I later discovered that, after cleaning, I didn't reinsert the head gasket (but I'm not certain whether the valve and the perimeter of the head device head are blocked or not due to the potentially-drying bean contents)
I tried shaking it some more as well as the "release pressure" instructions that came with the manual to no avail - nothing comes out regardless of orientation.
Questions
How can I tell whether there's too much pressure or too little pressure?(Now asked as a separate question here.)- How can I safely remove the device head in case there is too much pressure and the valve and device head are blocked? (and, as spongefile asked, hat's the worst thing that can happen?)
Any pointers are enormously appreciated!

I don't know how to tell what the pressure is on a whipper, but from the results of a blocked one, I'm going to make the following suggestion for attempting to safely disarm it:
- You need containment. If you open the container too quickly, you're looking at a massive mess to clean up. I'd suggest possibly a cardboard box (disposible) or a large plastic container (cleanable), with a clear plastic trashbag over it, so that only your arms are going in. If you don't have a large clear plastic bag, you'll either need to make a window (we can cut a cardboard box, then tape the bag down) or find something else clear (shower curtain liner?). Containment also reduces the odds that the head will fly off and damage something.
- Goggles or other eye protection wouldn't hurt incase something goes wrong.
- Place the containment vessel on its side, with the whipper inside, and the opening so that you can see into it.
- If you have assistance, tape the bag around your arms, so you have a good seal.
- Slowly open the container ... if it's like the case when my mom did this, a little will leak out after a while. Give it another partial turn, and some more will leak out ... go slowly. Suddenly, the whole thing will release, making a complete mess.
If you're like my mom, and insist on attempting to save the whipped cream, you can place a bowl & spoon into the containment with you, and scoop it off as it oozes out the side ... but risk knocking the bowl over when it suddenly pops open on you.
...
That being said, if you're not in a rush to open it, I'd let it sit for a day or two, with the nozzle up, (possibly after rapping it hard on the floor a couple of times) then attempt to spray ... if you get a gas release, you might be able to depressure it some before attempting to open it.

How do you depressurize a whipped cream dispenser?
Point cream whipper into sink or trash and squeeze trigger until pressure is released. Lid may now be removed. Do you find this helpful? Just hold the handle with the nozzle pointed up, and all of the gas comes out.Can I open my whipped cream dispenser?
If you're already done using your whipped cream canister and want to clean it, you'll need to open it up. However, you'll need to empty the canister first as the built-up pressure inside from the nitrous oxide gas can make it near-impossible to open.Why is my whippet canister not working?
Top. Sometimes the whipping siphon can get clogged, either from over charging it or through particles in the liquid clogging it. If it is due to particles you can try shaking the whipping siphon in different positions to remove the particles. This often works when it's a simple issue of being clogged.How does a whipping siphon work?
When a pressurized liquid is forced out the nozzle of the whipping siphon, the gas escapes from the liquid, aerating the liquid and turning it into a foam. The foam can range from a quickly dissolving froth to a heavy duty, dense foam through the addition of thickeners and stabilizers.5 Essential Siphon Whip Techniques

Answer 2
I don't know that there is a clear way to tell if the canister is over-pressurized. The typical number of cartridges used depends on the size of the whipper (usually 1-2 for 0.5L and 2-3 for the 1L). While it could likely take more pressure, I wouldn't exceed 3 cartridges in any application.
The mix of beans and whipped cream needs to be SUPER smooth for it to flow well in this application. Any type of chunks can clog the nozzle and become a real pain/mess. I suspect the leakage from the container initially was from not replacing the gasket. The way I think about it is, if you can perceive particulate when the mix is on your tongue, it's still too chunky for the whipper.

I know this was solved a year ago, but the problem was probably that it had no pressure at all. Without the head gasket, they almost always fail to seal and you lose pressure pretty quickly.
