Rancilio Silvia powered on but no heat - Page 2

One more thing. I think I'm confused about the safety thermostat. Whatever trips has a little red button that is accessed by removing the top cover of the machine and contorting your finger amongst wires to press it. The BOL stays on when this is tripped.

Remember: Here at Roadrunner cafe we're not happy 'till YOU'RE not happy.

When the safety thermostat (165 degrees C) trips, all lights should go out and Silvia is "dead".

I agree, they should go out. But they don't. The orange light is really just an indicator of the status of the thermostats (light is on when both are closed). If the safety stat is tripped, the light can still be on (either if both stats are calling for heat, or if there is a short to ground at the heater/boiler interface).

Note: The picture of the boiler that you see is THE ORIGINAL boiler that RANCILIO no longer sells or installs on Silvia.

Jim is correct - you would think I would be able to read my own adaptation of Silvia's wiring diagram.

Unfortunately, I did not learn this by referring to the diagram. Instead, I conducted a full scale test on a machine specially modified with a shorting wire across the steam thermostat :-0

Thanks for all the info. I'm in over my head though. I called the tech dude, Roger at Chris Coffee who was totally friendly and helpful. He has the opinion that it's the brew thermostat and is sending one. I'll let you know how it goes.

I'm not sure anyone is interested in this anymore but I just received the thermostat and have installed it and just turned on the machine. I'm so excited I'm going outside and watch the grass grow until it comes up to temp.

Did that fix it?

Greetings Bob:

First and foremost, I am sincerely happy for you that the machine is working - at least that is what I gleaned from your "Is anybody still interested post". I believe it is GREAT that you posted a follow-up - lots of times people don't.

HOWEVER, I for one believe you UNINTENTIONALLY left something out of your original troubleshooting as replacement of the brew thermostat would NOT have solved your problem as stated.

Perhaps your Silvia is wired a little differently than the schematic I posted earlier?
