Descaling a heat exchange machine

After 5 years, I decided to descale my HX machine.
With my old Gaggia, it was a breeze and I knew I was in for a much harder job.

I've always used purified water and a look inside the brew head showed little scale but I read up and watched videos and prepared for the job.

It's a long process of filling the resevior with Desale, filling the boiler with 1/4 of the tank, letting it run through the hot water wand and repeating for about 4 hours and tilting the machine to overfill the boiler above the normal fill line and flushing with 2 tanks of clean water.

I could tell by the blue green tint that I had accomplished a good cleaning and am glad I did this job instead of shipping off my machine for what I felt was good preventative maintainable.
