Too bad this problem doesn't seem to have a solution yet. I live in The Netherlands (also [email protected]) and am having the exact same issues with my first pinball machine!
It's a Pirates of the Caribbean and I already ruled out the switch itself by keeping that on and just pulling the power plug. 4/5 times I don't have any issues but that 1/5th time the fuse in the house trips and I need to reset that.
I keep the pinball machine plugged in and can reset the house's fuse without any issues. So there isn't a constant short circuit or something.
Houses here have a 16A fuse per group. No other power intense devices are on this same group of outlets and I already moved the pinball machine to other outlets in the house to rule that out.
Also no visible damage to the power cord and no fuses are blown inside the machine since the house fuse was faster I guess.
I have a multimeter but am not sure how I can resolve this issues with that.
