My machine is starting to warm up and then before it is ready to start steaming it trips the GFI. I have only used the machine twice. It worked fine the first two times.

Ok this unit will draw about 13amps (if your supply voltage is 120v) so it’s worth checking your outlet can supply that amount of current in the first instance, it sounds like your first outlet couldn’t and you now have a break in that circuit and the heat from the current draw has melted the supply cable, if the unit has lights and is plugged into an outlet which can handle the power draw and the lights don’t illuminate then check the fuse. If you replace the fuse and it blows again or the unit simply won’t heat then the element is busted
