My Indesit iwc6125s trips electrics ?

When we start the machine from the start after 5mins or so it will trip the electrics.But if we choose an individual setting i.e rinse,spin or drain it will work perfectly.What could the problem be? We had an electrician who came out yesterday,didn't check the electrics literally looked at the machine and said it was that.
The machine is only 3years old.We would prefer to try & fix the problem as it' a great machine.

Any suggestions would be greatly appreciated.
Thanks!
