I am certainly no electrician or expert, but I'll share my thoughts...
First guess: I am 99% sure that your power may be wired wrong in an attempt by someone to bridge US and EU power. The blue wire you mention should be the EU "Return" line. The brown is the "Hot" line. With that blue line connected, everything off, and disconnected from shore power do you have continuity between the 220 power line yellow/green and blue? If there is not, without turning on the generator or plugging into shore power, turn ON the AC breaker for the unit in question and check continuity. I believe that if you find continuity you need to find an electrician.
Next test is plug into shore power. Have all of the breakers off. Check for voltage between blue and shore power yellow/green. If you have voltage there is a shore power wiring problem...find an electrician.
Second guess is that the ground fault is at the A/C that you removed the return (blue) wire. Removing that will prevent the ground fault to be sensed. Possibly the saltwater path and the electric current path are somehow crossed?
I hope these random thoughts help you find the issue.
BTW, I believe that the most common ground fault on a SM that is wired correctly is electro-thermal heating elements. Most common is the water heater, followed by the SM2k dishwasher, then the SM2k clothes washer.
I have seen way too many SMs shore power wired incorrectly for US schemes. Check the DVD I gave you for a job named: Shore Power Wiring or something like that.
