I am not so sure that this is a good idea. It sounds as though your new wiring includes RCD (residual current device) protection which is tripping due to a leakage current from your machine. You old house may not have had this protection. Your espresso machine may or may not be safe. Whilst powering it from a circuit without RCD protection will solve the tripping problem it may leave you exposed to electric shock. In a machine that combines water, steam and electricity within a metal case this is not a good idea.
I would suggest you get the sparky to explore what is causing the leakage current that is tripping the RCD. The first test would be to disconnect the heater and then see if the machine still trips the RCD.
