Just the losses to the environment from the E61 make any model that doesn't measure the at least the group head temperature woefully inaccurate, well outside of any useful range. If it could be modeled reasonably, HX machines wouldn't need a flush routine and wouldn't be outdated for today's coffees. Without at least a second sensor, it is pure fiction

That's in remarkable condition! I can't believe it's that complete too. It looks like it just got pulled out of service! Nice find!

I thought about that. I am going to give it a shot at least. I haven't removed the gauge yet. I am going to see if some glue works first. And that video link was really helpful. I appreciate that

Maybe, but I'm sure they have a thermal model of the device to calculate an approximate offset. I doubt it's pure fiction

If there's any delay in returning, I would ask the roasters about how long after roast the coffees become stale enough that they'd offer poor resistance

Looking at the parts diagram at {link} I only see a temperature sensor associated with the boiler. If that is the case, the "brew temperature" indication is a fiction that probably has only marketing value

I think I'm going to get on the pre-order. The cold brew feature is awesome, and having to just fill one big tank vs. the exact amount of water is time is a really attractive feature for me

Perhaps a new fermentation process using natto

Same. The magnets are quite strong. Brad

Il Vecchio: I may certainly have done something wrong when replacing the piston gaskets, it is my first time at it of course. The 'sticking out ends' of the gaskets were seated facing 'outward', which I think allows the tiny holes on the piston to pressurize the hollow part of the gasket and 'inflate' it under pressure, increasing the
