I solved a problem like this on FIXYA, just a few months ago. I gave this solution. Try to fill the machine from somewhere else. You can do this from the outlet. If you manage to do this, put on the machine. ( now you know that when there is hot water in the machine, the tap goes round free for safety). Now as the water starts to cool down....start trying to see if you can unscrew it. My plan is that with the hot water, the safety will start to work again. If the cap does not release the safety on cooling, then there is no other way but to destroy the cap and replace with a new one. Very important to mention that this job must be done by a qualified technician or some one who knows what he is doing. Working with hot water is very dangerous.

Have you tried cleaning out the small filterfrom the reserve tank? Also, check the tank/resevoir valve is operating properly, when you take it out to fill try to make water release from tank.

you need to even the canister pressure. Release the valve from the handheld device, i.e. it needs to be plugged in and pressed. Presure also exists at room temp.
