Tefal Pro Express Turbo ?

Hi - our Pro Express is spewing tons of steam out of the base (generator) Tefal troubleshooter says its a safetu mechanism on the generator but doesn't say what causes it. Any help greatly appreciated.

Anything I can do to fix it?

At a guess either a blockage or a pressure valve has failed
