How to Fix / Troubleshooting
Safety first: Turn off and unplug the unit before cleaning sensors.
Verify brew configuration:
- Ensure the correct carafe or cup is placed on the warming plate or cup platform.
- Select a brew size that matches the installed vessel (e.g., do not select full carafe with only a mug present).
Clean carafe sensor area:
- Wipe the warming plate and surrounding area with a damp cloth to remove coffee residue.
- Inspect any visible sensor windows or levers and clean gently.
Reset:
- Unplug for 5 minutes, then plug back in and reselect brew size.
If E08 persists, the carafe detection sensor or associated circuitry may need professional service.
