Question about Rancilio Silvia Espresso Machine
It may be that the 'shower screen' which is a perforated metal disk filter that fits inside the head has reached its use by date.
These can be found and bought on E-bay for about $15 each, make sure you buy a genuine Rancilio replacement, while you are at it, replace the rubber 'group seal' - a rubber ring for pressure sealing the head/arm after filling the arm with grounds - these are a similar price. If you get leaks around the head while making a coffee, the seal is worn out.

SOURCE: not heating up the water
3 things could be wrong. First is easy to check. With machine on, turn on the steam switch and after about a minut open the steam knob and push the middle switch. Check the water coming from the wand and see if its warm? If it is you need a brew thermostat. Unplug the machine. Remove the water tank. Remove the 4 screws that hold the top on and lift top off. The boiler has 2 thermostats on the top front of the boiler, and the one with the red dot is the brew thermostat and need replacing.
If that didn't fix your problem there is a reset thermostat on the front face of the boiler and has black wires going to it. There is a red button in the middle of the thermostat and needs to be pushed.
If that one didn't solve your problem you need a new heating element. You can do a continuity check on the terminals.

SOURCE: no water through group head
More than likely your 3 way valve is stuck. It is located behind the front panel and when the 2 screws are removed it slides to the right. Unplug your machine before working on it. The 3 way valve is on the left and you can remove the dispersion tube on the bottom(unscrews) 14mm nut holds the solenoid on and you can slide the solenoid down the shaft. The big nut at the top of the shaft will unscrew and there you will fin the solenoid inside with a big spring. If its not stuck it will slide out and you probably need a new 3 way valve, but more than likely its stuck. Some times just tapping the nut on something hard will unstick the solenoid. Clean good and reinstall.

You need to change the group head gasket. They only last about 1 year and then should be changed. Get 2 because they usually fail on Friday and you have a party on Saturday.
The gaskets get hard from the heat and don't form to the filter any more so they leak.
When you get the new gasket.
Empty everything out of the machine (water tank, drip tray, etc.) Turn the machine upside down on a towel. This way you can see what your are doing.
Remove the filter screen and diffuser from the brew head. The black O-ring is your gasket. Carefully pry it out. Clean the opening good before you install the new gasket. Insert the gasket with the beveled side down (on the inside edge of the O-ring is the bevel). Once you have the gasket in place, use the portafilter to finish seating the gasket.

The second one is your relief valve return water line. It just sets in the tank. Doesn't go anywhere.
