How to Fix / Troubleshooting
Safety first: Do not repeatedly reset the breaker. Unplug the coffee maker and keep it unplugged until the fault is resolved.
Moisture check:
- If the machine was recently descaled or spilled on, allow it to dry for 24–48 hours in a warm, dry place.
Electrical inspection (qualified persons only):
- Inspect the mains cord and plug for damage.
- Open the base and check for water traces or corrosion around the heating element and control PCB.
- Use a megohmmeter or insulation tester to check for leakage between the heating element terminals and chassis.
- Replace any component that shows low insulation resistance or visible damage.
Because this involves safety-critical earth leakage, professional service is strongly recommended.
