Possible Causes
Shorted heater causing overcurrent, Faulty thermal fuse opening instantly, Defective control PCB detecting fault, Internal wiring short to chassis
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker immediately and do not attempt to operate it again until inspected.
- Check for visible damage: Remove the bottom cover and look for burnt components, melted wires, or scorch marks.
- Test heater and fuse: With a multimeter, test the heater and thermal fuse for shorts or opens. Replace any failed components with correct-rated parts.
- Inspect wiring: Ensure no wires are pinched or contacting sharp metal edges.
- Control board: If hardware appears intact, the control PCB may be falsely detecting a fault and shutting down; replacement may be required.
