My dream machine quit halfway into an extraction today. The on light remained lit but there was no heat to boiler. I Checked the thermostats and both are blown (ie. not functioning). Question to forum: Do I need to replace just the thermostats or did they blow because the boiler is shot?
Sounds like the heating element is fried. How did you determine both thermostats were bad? Check power across the terminals if there's voltage and the machine is cold, there's your answer. If there's continuity to ground across any terminal, it's shorted out.

Before replacing a costly boiler check for continuity across the heating element. If it's open it is indeed ruptured and the upper boiler half needs to be replaced. If there's continuity then the heating element is fine, and it's either not getting voltage or has no path to ground. You'd then want to look at the fusible link clipped to the top of the boiler or one of the thermostats.
