TEFAL STEAM GENERATOR IRON REPAIR AND CLEAN

Steam iron throws dirt and limescale while ironing clothes.
Tried everything but doesn't work so I completely opened and cleaned properly.
Now it works perfectly.

I have the same iron, all the lights are flashing and nothing works, what do you suggest to try cleaning the boiler tank

What if after replacing the sollenoid valve (with ove rpressure savety), the steam still comes out through the over pressure valve? I cannot find the pressure switch in the system. It's a Tefal GV7556
