Possible Causes

Water leak onto electrical parts, Shorted heating element to chassis, Damaged power cord, Internal wiring insulation failure

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset the breaker. Unplug the machine immediately and keep it unplugged until the fault is found.

  • Inspect for leaks: Check around the water tank, boiler, and base for signs of water. Fix any gasket or hose leaks before further use.
  • Check power cord: Replace the cord if there is any visible damage or if it feels unusually warm in use.
  • Visual inspection (advanced): Remove covers and look for burn marks, melted insulation, or corrosion on wiring and connectors.
  • Test heater to ground (advanced): With a multimeter, check resistance between each heater terminal and the metal chassis. A low resistance indicates a ground fault and the heater must be replaced.

Because this fault can be hazardous, if you are not trained in electrical repair, have the machine inspected by a professional.
