Espresso Love

It has been a long time since the espresso has been flowing in the Mark home. My Expobar Office Pulser functioned perfectly for several years and then........ bam. I blew a pressure relief valve. We all know how clear hindsight it, right? Well before I was blessed with that form of vision I ripped her open and started poking around.


By the time I was done, I had damaged at least two parts. One, a hard to find, pressure-regulating diaphragm and the other a needle valve. My friend Chuck took the pressure diaphragm to his shop and crimped it back on. Kathy at Wholelattelove.com tech support explained that I needed to descale the needle valve, reassemple, test, and retest until I have the pressure adjusted properly.

Turns out all I had to do in the very beginning was push a little red button to reset the boiler.


In the interim, approximately 12 months, Starbucks has been reaping the benefits of me not having a functional machine at home. Boy, are they going to miss me.





As of yesterday, I have the machine running perfectly again - churning out tasty machiattos, lattes, Americanos, etc. All's well that ends well.

Darius, where is the red reset button?

On top of the boiler there are a couple of objects. On is a nut with a metal pin stickig out of it, one is an electric device with two wires going into it. Between those two wire is a tiny (pin sized) red button. Turn off your machine and press that button - it is the boiler reset button. It works like a fuse and "blows" when the boiler overheats. The boiler would only really overheat if it was left on empty or close to empty (that is what happened to mine). I can send you some schematics if this doesn't help.
