Better yet, when you get the citric acid.  Remove the probe plug and put ~1/8 cup of citric acid in the boiler.... turn the heat on and let it sit for a few hours.... then run water through the group head, steam wand, hot water wand.... everywhere.  Sounds like it needs a full descale.

Joe, by the sounds of it, you are going to need to descale that whole machine. You can get it working temporarily but it is only a matter of time before you are going to be shut down again. From my experience with the same machine you own, the biggest problem you will face for a descale is draining the boiler. Mine had no drain so you have to pull the end off with the heating element. You could do an inline descale if you use citric acid instead of sulphamic or other more rapidly acting acid. You would need to do a significant and repeated flush of the boiler though to get it all out.

Good luck.

Descaling a HX: http://home.earthlink.net/~r_harmon/descaling%20a%20HX%20machine.htm


Thanks Tex !!!!


If the machine shows significant scale I like to remove the element, tap the exterior of the boiler with my leather mallet to dislodge the scale, and flip it up on its side and rinse the loose scale out with a water hose. Then reassemble it and continue with a regular descaling. It's a matter of scale (pun intended ;D).

Howdy Folks,

A few days after I lasted posted back in March I ended up going in the hospital for open heart surgery !!! So after all these months of recovery I'm just getting back to this project.I really miss my espresso machine.Its been out in my shop since last spring.The shop is not heated so its now on a table in our dining room.The heat is on to fix it now.

Well, obviously you survived the surgery, so let's get your machine pumping too. Please refresh our memories; what's it doing/not doing?
