Descaling your espresso machine is a necessary thing. The exact procedure was hard to find, I ended up finding lots of information about it, none directly related to the machine I had. This guide is what i filtered out of the wealth of online info.

This project is in the moderate to advanced category of espresso machine maintenance. Which is probably why it is often such a feared procedure. If you are not fairly comfortable digging around inside your machine, unplugging and plugging in wires, please find someone who is. Basic mechanical skill is required; please get some help if you are unsure. I am not responsible if you damage your machine and void its warranty.

My obsession with temperature all started after I installed Eric’s T.C. Adaptor. I was flushing 8 ounces of water to get to the top end of brew able temps. In between shots I still needed to flush 6 ounces at least to keep everything cool enough to brew nice tasting shots. I was using lot of water, almost a gallon per day. I even have an external tank but that is another story.

Not only can I see the brew temperature with Eric’s T.C. adaptor, I can also see what temperature the group was at idle, 220º.

i researched and found about the thermosyphon restrictor that can be inserted in the thermosyphon to make the group cooler.
