Question edited for clarity, remove text speak and toss in a load of CAPS.
According to the advertising, it is supposed to pump and generate loads of steam continuously.
Steam ironing Recommendations: To prime the steam circuit, either before using the iron for the first time, or if you have not used the steam function for a few minutes, press the steam control button several times in a row, holding the iron away from your clothes. This will enable any cold water to be removed from the steam circuit. • To obtain steam, press the steam output button under the iron handle. The steam will stop when you release the button. • After approximately one minute, and regularly while it is being used, your steam generator's electric pump injects water into the boiler. It makes a noise but this is quite normal.
I would try a liquid descaler like CLR and try to get liquid up into the head of the iron as well. My thought is that something is stuck with scale buildup.
The Tefal website has Customer Support and also says they are repairable.

Hello again Julia
Despite my searching, I find that you are the only person to have this issue. I am guessing that you has a split in the steam tank, a bad connection to the steam tube, or a split tube. The only way would be to strip it down or take it in for repair. You could try contacting Tefal and see if you can get a warranty repair on it. Even if it is out of date, you can still ask.

Next time it happens and it trips.. use a dry towel to unplug kettle, just in case.
Is the base wet? Check the kettle for cracks. Check the cable. Is it damaged? Try replacing the fuse in the plug. Is the steam that the kettle produces affecting lighting or other electrical items around it? Try moving the kettle to a different location.
Check the power supply: Make sure that the iron is properly plugged in and that the outlet is working. If the outlet is not working, try plugging the iron into a different outlet.
Check the temperature setting: Make sure that the temperature setting on the iron is set correctly for the type of fabric you are ironing. If the temperature is set too low, the iron may not heat up properly.
Check for mineral buildup: If the iron has not been descaled recently, mineral buildup in the steam chamber could be causing the heating element to malfunction. Try descaling the iron following the manufacturer's instructions.
Check the heating element: If the heating element is damaged or has burned out, the iron will not heat up. In this case, the iron may need to be repaired or replaced.
There are a few possible causes for your Tefal iron cutting out after about 10 minutes of use:
Overheating: The iron may be overheating and shutting off as a safety measure. This could be caused by a clogged steam vent or a malfunctioning heating element.
Electrical issues: The iron may be experiencing electrical issues, such as a faulty power cord or a problem with the outlet.
Water leaks: If the iron is leaking water, it could be causing the iron to shut off. Check for any visible leaks and make sure the water tank is properly sealed.
Malfunctioning thermostat: The iron's thermostat may be malfunctioning, causing it to shut off unexpectedly.
Re-read the instructions as you may have missed a step setting it up. I've done it setting up power tools. Some steam irons need to be in a specific function setting or a certain heat range for the steam to work. If it still refuses to work take it back to the store you bought it from with the receipt, (If you still have it?), as they usually have electricals covered by a guarantee or a warranty against manufacturing faults.
