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.

SUGGESTED CLEANING SCHEDULE
Type of Water Cleaning Frequency
Soft water every 80 brew cycles, Hard water every 40 brew cycles
Your espresso maker may be delimed using one quart of white household vinegar. Clean the water tank first, following steps l-5:
1. Make sure the steam control knob is in the center off position and that the plug is disconnected from the electrical outlet.
2. If the machine is cool and the pressure has been released, remove the pressure cap and pour 10 ounces of undiluted white household vinegar into the water tank.
3. Screw on the pressure cap and allow machine to sit overnight with the vinegar solution in the water tank.
4. Remove pressure cap and discard vinegar through the top opening of the espresso maker.
5. Rinse the water tank thoroughly with tap water, repeating this step twice.
To wash internal parts:
Make sure you clean the inside of the water tank first. Remove the pressure cap and pour 10 ounces of fresh white household vinegar into the water tank. Screw the pressure cap back on top of the water tank. Make sure the cap is on tight. Insert the filter holder into the brew head and place the glass decanter with lid on the drip tray. Plug the machine into the electrical outlet and turn the power switch on. An indicator light on the power switch will tell you the machine is on. Place a cup with cold water under the steam nozzle. When vinegar begins to flow into the decanter, insert the nozzle into the water and open the steam nozzle slowly by turning the steam control knob downward. After a few seconds, close the steam nozzle by turning the knob back up to center. This will clean any residue left in the nozzle from frothing milk. When all the vinegar has been pumped into the decanter and the flow has stopped, turn the power switch to the center off position and allow the machine to cool. Repeat steps 1-7 twice using only tap water to rinse any remaining traces of vinegar out of the machine.
1. Pour warm white vinegar in the decanter and let soak for 20 minutes.
2. Discard the vinegar, Wash and rinse the decanter thoroughly using a
soft cloth. Do not use harsh abrasive cleaners.
