As in title. The machine is nearly 9 years old (well out of warranty), and it's served me well so far.
It was working great until a couple days ago - when I tried to make my morning coffee and it tripped our RCD. All the other functions (grinder, warm-up, hot water/milk wand) work fine. But as soon as I start the shot it'll trip after 5-10 sec.
I took the machine to a friend's house. His house has no RCD in the fuse board, so I got one of those portable ones (the kind you use for camping etc) and plugged that into the wall socket, then the machine into that. I was able to successfully do multiple shots without issues.
Obviously something is wrong here - I guess my fusebox-mounted RCD at home is more sensitive than the wall plug kind?
I know my way around a multi meter, are there any common components that tend to fail in these machines that I could take apart and test?
