FYI - the flowmeters can get fried after lots of usage. Back in the day Starbucks used to put pieces of cardboard between the flowmeter and group head to prevent them from heating up. Aside from checking for scale you use test with an ohm reader. I think a functional one will reach 2.4ohm (or maybe 2.8). A broken one will post junk ohm information and bounce around. Replacing them is expensive so I'd just recommend usitng the semi-auto on/off switches. This info comes out of the big oragne Linea maintenance book.

Where is the steam coming from the small valve on the top or the big tall one? If it is the tall one then the problem is in the block electrical box(pressure stat) on the left above the element, that may be stuck and not telling the machine that it has enough pressure turn off the elements.

Check the thermostat on the top of the back boiler, if the red pin is up then, make sure that there is water in the boiler then push in pin and turn machine on. Now comes the exciting part we have to find out why the boiler overheated, is it because the elements are damaged or the pressure stat is not working properly.

No, just make sure that you rinse well and pull a shot and let it drain so that you do not serve soap to anyone.
