Possible Causes

Carafe not detected, Water tank empty or not seated, Brew basket door not closed, Faulty start button or keypad

How to Fix / Troubleshooting

Safety first: Unplug before physical inspection; plug in only for testing.

  • Verify setup: Ensure the water tank is filled and seated, the filter basket is installed and closed, and the carafe is correctly positioned on the warming plate.
  • Check indicators: Look for any icons on the display indicating missing components (carafe, tank, lid). Correct as indicated.
  • Test start button: Press the start button firmly. If it feels unresponsive or only works intermittently, the keypad may be failing.
  • Reset electronics: Unplug for 10 minutes, then reconnect and try again. If the machine still refuses to start with all components in place, the control PCB or keypad likely needs service.
