Possible Causes
Faulty flow meter, Control PCB not stopping pump, User mis-set brew size, Blocked drip-stop causing delayed flow
How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool if overflow occurs.
- Verify brew size: Ensure you have not accidentally selected a larger brew size than the carafe capacity.
- Check drip-stop: Make sure the drip-stop valve moves freely and is not sticking closed, which can cause sudden surges.
- Test with water only: Run a cycle with water and an empty basket to see if the volume still exceeds the setting.
- Service control system: If overfilling continues, the flow meter or control PCB may be malfunctioning and should be serviced.
