Profitec Pro 700: Brew Boiler Tripping GFCI

Use this article to determine if the brew boiler element is tripping the GFCI.

Before doing this we recommend verifying that the machine hasn't tripped one of the safety switches when attempting to heat. If the machine has tripped the safety switch(es) while trying to heat the coffee boiler, the issue isn't coming from a ground fault condition.

We recommend turning off the machine and unplugging it before attempting this.

Tools required:

  • 2.5mm Allen Wrench
  • Multimeter (optional)

1. Start by removing the panels from the machine.

2. Unplug the machine and then unplug one leg of the brew boiler heating element, shown below at the bottom of the boiler.

2. Reset the GFI, plug the machine back in with one element leg unplugged, attempt to turn the machine on.

3. Does it trip the GFI with one leg of the element unplugged? If no, then the brew boiler heating element is the culprit. You will likely need to replace the brew boiler heating element.

If the machine still trips the GFI with one leg of the element unplugged, unplug the other wire and repeat the above steps.

If the GFCI continues to trip, even after unplugging both element legs, the issue is not the element and will need to be diagnosed further to find the source of the ground fault.
