How to Fix / Troubleshooting
Safety first: Allow the machine to cool before disassembly or descaling.
- Verify water input: Confirm you are filling the reservoir to the correct level for the selected cup setting.
- Check for leaks: Look for water inside the machine or on the counter that might indicate loss before reaching the carafe.
- Descale: Run a full descale cycle to clear restrictions that can reduce flow.
- Inspect drip-stop: Ensure the drip-stop valve is not sticking closed or partially closed during brewing.
- If underfill persists: The flow meter may be misreading volume and could require replacement or recalibration by a technician.
