I have a Rancillio Silvia at work and it had enormous pressure when I first used it.
It is approximately 12 months old and makes around 12 cups a day average.
The problem is that the steam pressure has dropped substantially and it is hard to get good stretching qualities in the milk.
Does this machine need a service, or seals replaced?
Any assistance would be appreciated.

There is not a repair manual for the silvia, the most that can go wrong is the 3 resettable thermostat on the top of the boiler, remove the 4 screws on top of the machine for access. Unless you run the boiler dry. Then if the thermostats did not kick off in time then you will need a new boiler. You will notice a discoloration in the water out of the group or the steam valve.
There are a couple of things. 1. Your pump is not primed. Open the steam knob and push the middle switch. 2. Your intake hose is pinched or not connected to the pump, or your intake hose is not in the water tank.
This is not an unusual issue, but an unusual fix. When appliances that use water and heating elements use a ground fault breaker, it often thinks there is a problem to ground, since it is not the regular short to ground like an element. Move it to an area that has a regular outlet, and turn it on the first time. From then on, it should work right.
Could be several things. Is it new and the right one? Sometimes the gasket gets loose and comes down a little. Try pushing it back up with something that won't puncture it (such as the non-writing end of a Bic). Make sure that the basket is pushed in the handle all the way.
