LUCCA A53 / A53 Mini: Machine Tripping the GFCI

If your La Spaziale LUCCA A53 or A53 Mini espresso machine is tripping your GFCI outlet, follow along with these steps to fix the issue.

When machine is plugged in:

If the GFCI is tripped as soon as the machine is plugged in, the SSR may be the faulty part and may need to be replaced. Try unplugging the wires going to the SSR one at a time. Plug the machine in after unplugging each SSR wire to check if the GFCI still trips. If even one of the wires going to the SSR trips, the SSR will likely need to be replaced.


Alternatively, there may be a wire grounding out somewhere within the machine that needs to be found. If this is the case contact us at support@clivecoffee.com

When machine is turned on:

If the machine trips the GFCI right after you turn the machine on, the faulty part is likely the fill solenoid or within the coffee boiler triac. If this is the case contact us at support@clivecoffee.com

To continue troubleshooting, remove the panels of your machine.

If the machine trips the GFCI a few moments after it's turned on:

It's likely somewhere along the coffee boiler triac. By unplugging the following things one at a time and turning the machine on, you can determine which part is faulty. Once you find the part that makes the machine not trip the GFCI when turned on, you've found the culprit. Before touching any wires, unplug the machine from the wall. Then plug it back in to test it.

*NOTE: If your machine is in 20 amp mode, you will need to also check the steam boiler places listed below as the machine will fire all things up at the same time in 20 amp mode.

-Safety Switch-

After coffee boiler heats up:

If your machine heats up to the proper coffee boiler temperature and then trips the GFCI, you will likely find the problem component within the heating triac of the steam boiler. You will know the coffee boiler is fully heated when the numeric lights on the control panel stop flashing and remain solid. Follow along with these steps to find the issue by unplugging one piece at a time, turning the machine on to test if it trips the GFCI, and then plugging it back in to move onto the next part. Once you find the part that makes the machine not trip the GFCI when turned on, you've found the culprit. Before touching any wires, unplug the machine from the wall. Then plug it back in to test it.

If none of the above are causing the machine to trip, there is likely a wire within the machine that has a split casing and is grounding out on the frame of the machine. You will need to locate the wire and fix/replace it. Contact us at tech@clivecoffee.com with any questions.
