Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker and let it cool completely. Do not attempt to bypass any safety devices such as thermal fuses.
Basic reset:
- Unplug the unit for 10 minutes, then plug back in and attempt a brew with water only. If E6 appears immediately and no heating occurs, internal components are likely failed.
Technician-level checks:
- Remove the bottom cover and test continuity of the heating element and thermal cutoff with a multimeter.
- Inspect wiring for burned or loose connections.
- If the heater circuit is intact, the control board triac/relay is likely defective and the board should be replaced.
Because this involves mains voltage and high temperatures, professional service is strongly recommended.
