I got my Silvia from you over 11 years ago and we've used it daily since, obviously very happily and with care. We've developed a steaming problem: she heats up normally, the light goes off after about 20-30 seconds, and I begin steaming - all normal. But the steam diminishes from full to nothing in about 15 seconds, at which point the light goes back on. If I then leave it for 60 seconds, the light goes off again and she steams perfectly. It makes no difference if I leave her heating up for steaming for over a minute to begin with, the sequence of diminishing steam then one minute to reheat is identical. I'm stumped.
Have you descaled the machine recently/frequently? If the machine is clean I would recommend replacing the thermostats. Given the age of the machine I would also recommend replacing the group gasket if you have not done so.
