Espresso Pure - temp too high?
« on: August 04, 2017, 05:29:45 AM »
I carelessly bought a Craigs List Espresso Pure while dealing with a poorly-performing Espresso. I descaled and cleaned it and I find that the steam light goes on after a while regardless of whether I've engaged the steam switch. If I open the valve there is steam and if I make coffee the shot will start out steamy. (There is more steam when the switch is engaged.) It seems like the water temperature thermostat is simply too high. Does that seem right? I think I can get some idea of how hot it really is by letting it warm up enough that all the boiler-connected parts are hot and hold a digital thermometer against the boiler or just pump hot water onto it. If it's much above 195 deg, it's too hot, yes? Are replacement thermostats pretty reliable, or are they all over the place?

Sounds like you're on the right lines there - though IIRC the brew tstats are set to 95C / 203F - the boiler should cycle around or near to this value (can go up around 10F above the set point). If materially higher than this then yes you need a new brew tstat. Holding a temp probe against the boiler next to the tstat is the way I would do it, if you run water out of the boiler the water temp will drop 20C / 36F in a matter of a few seconds.
