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.
