I have a Rancilio Silvia machine. We forgot to turn it off one night. Since then, I can have hot water and it is making the coffee fine but I have problems with the steam. The steam works only for about 10 seconds, then the nozzle stars spitting hot water instead of steam. Everything else looks like it is working: When I turn the steam button on, the light will turn on for few seconds, as it did before when the machine was heating the water, then turn off, indicating the steam should be ready.
