Possible Causes

Incorrect brew size selected, Carafe not empty before starting, Drip stop malfunctioning, Control board miscalculating volume

How to Fix / Troubleshooting

Safety first: Unplug the unit and allow hot surfaces to cool before cleaning spills.

Check usage:

  • Ensure the carafe is empty before starting a new brew.
  • Select the correct brew size that matches the carafe capacity.

Inspect drip stop:

  • Verify the drip stop is fully open and not restricting flow.
  • Clean the drip stop and basket as needed.

If overflow occurs even with correct settings and a clean drip path, the control board or flow sensor may be misreading volume and should be serviced.
