How to Fix / Troubleshooting

Safety first: Unplug the coffee maker immediately. Do not repeatedly reset the breaker or replace fuses without addressing the cause. Risk of fire and shock.

  • 1. Try a different outlet
    • Plug into a different circuit to confirm the issue follows the appliance, not the house wiring.
  • 2. Inspect power cord
    • Check for visible damage; if present, do not use the unit until the cord is replaced.
  • 3. Internal inspection (advanced)
    • Unplug and remove the bottom cover.
    • Look for burnt components, melted insulation, or wires touching metal parts.
  • 4. Test heater
    • Use a multimeter to check the heating element for shorts to ground.
  • 5. Replace faulty parts
    • Replace any shorted heater, damaged wiring, or burnt control board before using the coffee maker again.
