Rocket Espresso Electrical Short / Ground Fault

The machine trips the household circuit breaker or RCD when turned on or during heating.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Shorted heating element to ground, Damaged power cord, Water leak onto live components, Failed control board component

Safety first: Do not repeatedly reset a tripped breaker. Unplug the machine immediately. There is a risk of electric shock and fire.

Inspect for leaks: Check under and around the machine for signs of water. Internal leaks onto electrical parts are a common cause.
Check power cord: Examine the cord for cuts, burns, or crushed sections. Replace if damaged.
Element insulation test (advanced): Using a multimeter, test the resistance from each heating element terminal to ground. Low resistance indicates a ground fault, and the element must be replaced.
Professional service: As this involves mains voltage and potential water contact, have a qualified technician diagnose and repair the fault.
