How to Fix / Troubleshooting
Safety first: Unplug the coffee maker before inspecting cables or boards.
- Hard reset: Disconnect the machine from power for at least 10 minutes. Press and hold the power button (if accessible) for 10 seconds while unplugged to discharge capacitors. Reconnect and test.
- Check outlet: Plug the machine into a different, grounded outlet without extension cords or power strips. Unstable power can cause control errors.
- Inspect external connections: If your model has a detachable control panel or display, gently press around the bezel to ensure it is seated. Do not pry it open.
- Surge protection: Use a surge-protected outlet to prevent future PCB damage.
- If E08 remains: The main control board likely needs replacement and firmware programming. This is not user-serviceable; contact Ariete support.
