After about 8h of hard work, today I finished cleaning, fixing and reassembling the #saeco coffee machine I use on holydays. The boiler had something like 3mm of limescale that had to be scraped using a sharp knife and sanding paper. No, limescale remover didn't do anything at all. I changed all main seals and the shower filter for 15 euros. Preventing something from going to the bin is very hard work.
typical saeco hairy wiring. I wonder if they do it on purpose to scare people off. on the left the fake espresso system inside the filter holder. if you can spend a bit more, just buy a Lelit and keep it for life.
