I have a three years old silvia with a Auber PID. I can pull my shots OK, and i can get staple temperatures and the unit behaves normally, but when i want to steam milk, the boiler hangs at 135C, when it normally goes up to 150C, and i can hear pressure leaking out from somewhere.

Silvia has two bimetalic switches that control the boiler temperature. One for brew water and one for steam. They are not exact and they can go bad. They are cheap and easy to replace. Just Google for Rancilio parts.
A much better fix (and more expensive) is to switch to PID control. Google for Rancilio PID control. The conversion is $250+ but once you've gone PID, you'll never go back. The temperature is exact, fast, and totally under your control.
On the happy side, if you tried to re-heat the boiler and found this problem straight after it failed, the thermostat may still re-set once the unit cooled down. So leave it a day and try again. Alternatively, it could be a burnt out fuse or on the less happy side, a burnt out boiler.
If no lights come on its a failed fuse. But if everything else is normal but it still wont heat, the best option is to take it for a service to a qualified technician as it may be that the boiler was damaged.
First things first, remove the screw and shower in the head and clean. Then change grind to something a little coarser, since we are testing the machine we will not tamp the coffee(we are doing this to have a constant in our coffee brewing equation). Note how long it took to brew, if it brewed longer than 40 secs, then adjust grind and try again. If coffee shots looks better and taste better then we are on the right track, we are looking for any thing between 15 and 30 sec depending on the coffee blend from light to dark. If you are getting the same results over 40 secs for a shot no matter what grind you use then the pump needs to be replaced.
It definitely needs preventive maintenance once a year. There could be a couple of issues causing watery espresso. You could have a clogged shower screen or cracked porta-filter basket. They bypass valve from the pump could be leaking causing low pressure (check this by pulling a shot and seeing if water continually flows back into the tank via one of the water hoses).

The staples do not go on the bar you pull back but directly into the bottom once you have pulled the bar back. I was trying to put the staples on the bar at the back and push them into the stapler.
