Is it possible that the iron has overheated or that the pressure inside the iron is too high?
The pressure and temperature are controlled by a pressostat and a thermostat respectively.
If the pressure or the temperature becomes too high, the boiler is switched off automatically.
The boiler will cool down and the pressure will be released.
