Posted Fri Mar 21, 2014, 2:58pm Subject: New (for me) Expobar!
I had been getting tired of the temp swings on my Gaggia Classic and was ready to get the Auber PID kit (thanks to d4f all the guidance). The $200 would have been a reasonable cost compared to upgrading to something with more temp stability. Right before I went that rout I came across an offer on a used Expobar Office Pulser...for $275. My first question was "what's wrong with it?" I ended up taking the chance figuring that if there was a giant hole in the boiler I could probably sell it as is for more. Not the case...it appears to be in wonderful condition. I've only gotten to know the machine for about 3 days now and just wanted to open myself to anyone's general advice. Here is what I know about the machine:
*It's a 2006 Expobar Office Pulser *Previous owners claim they backflushed regularly and kept up with the water softener filter changing ...That's about all I know about its history.
I'm putting up some pics of the machine http://www.flickr.com/photos/121049162@N04/sets/72157642706449845/ and just want to invite any comments regarding what more knowledgable users see. Since I'm new to HX machines and E61 style groups, I'm doing a lot of reading on how they work and how to best use them. Links to any of your favorite articles regarding HX machines (or Expobar in particular) would be useful. My understanding that although the Pulser is not actually an E61, the mechanics it employs is identical.
Right now my one specific question regards the solenoid. On my Gaggia, terminating the shot created a pretty significant gush of water through the tube into the drip tray. On the Expobar, it's more like a dumping of water followed by some dripping for a few seconds (no continuous dripping). Is the difference just due to the different diameter of the tube leading into the drip tray (or if that's not normal let me know). There is no residual pressure left in the basket post-shot so I assume its functioning properly, just want to be sure.
Pressure gauge is on order so I can check the brew pressure (I don't believe it's above 10 bar though), and I'll most likely end up going with the Rancilio bottomless PF unless anyone has a better recommendation (I don't want to chop mine, and there was some negative comments regarding the quality of the factory cut Expobar bottomless).

Don't know about the 3 way on the Exobar, when you get your pressure guage you'll know if the opv is operating correctly. Either way if everything else is OK with the machine and internals are good, you scored a hell of a deal for that machine, congrats. People would pay that or more for that same machine even if it needed work, heck people pay 500 for Oscars that need to have parts replaced and cleaned up inside.

You got a heck of a deal. A steal really. I've got a Pulser from that era - great machine.
