Possible Causes
Leaking heating element to ground, damaged power cord, water ingress into electrical box, shorted pump or motor windings
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a breaker that trips. Turn OFF and unplug the machine. Water and electricity can be lethal.
Steps:
- Inspect for leaks: Look for water around electrical components. Fix any leaks before further testing.
- Check power cord: Replace if damaged or crushed.
- Insulation tests (advanced): Use a megohmmeter to test insulation resistance of heating elements and motor to ground. Replace any component with low insulation resistance.
- Dry the machine: If water ingress occurred, allow the machine to dry completely before retesting.
- Contact a professional: Ground faults are serious; if you are not equipped to test safely, call a La Marzocco technician.
