I notice that’s a 240V 10amp relay they’ve used. Do you think there is any electrical difference (aside from the plug pattern) between the US 110V version and the EU/Australian 220V one?

Thank you, that was a big help! The exterior on off button had come loose and was rattling around inside and I was able to repair it thanks to your tear down guide.
