Possible Causes

Brew basket not fully inserted, Carafe not detected on warming plate, Drip stop closed, Faulty START button or control panel

How to Fix / Troubleshooting

Safety first: Unplug the unit before reseating components.

Verify mechanical interlocks:

  • Ensure the brew basket is fully pushed in and latched.
  • Confirm the carafe is centered on the warming plate.
  • Open the drip stop lever.

Control panel check:

  • Plug the unit back in and try pressing other buttons to see if they respond.
  • If only START is unresponsive, the button contact may be worn.

If mechanical checks are good and the panel is unresponsive or intermittent, the control panel or main board may require replacement.
