Descaling: hidden dangers when not doing right

In this video, I show what I found in the boiler of my Gaggia Classic 2006 that I acquired 2nd hand for the Gaggiuino project and this is the start of the journey: after acquiring machine, a complete teardown, cleaning and overhaul.

But the main reason that I brought this alert is that after buying and opening the boilers of a few espresso machines, I believe that most people don't descale as often as needed, or not the right way, and they don't know how fast limescale is building up in their machines.

Besides the risk of permanently damaging parts, the coffee becomes tasteless and maybe a risk to your health as well.

Then, I bring some ideas to monitor and know when an intervention is needed, how to slow down the process, reducing maintenance intervals and saving some good money.

And I also share how I maintained my ECM Classika PID in the last 12 months, an easier, efficient and pragmatic approach.
