Possible Causes
Residual water in the outlet arm and tubing, slightly tilted machine causing a siphon effect, faulty check valve not sealing, overfilled reservoir above the max line.
How to Fix / Troubleshooting
Safety: Normal handling precautions; no live parts accessed.
- Level the machine: Ensure the coffee maker is on a level surface so water does not siphon unintentionally.
- Check fill level: Do not fill the reservoir above the maximum indicated level.
- Inspect outlet arm: Remove and empty any water trapped in the outlet arm. Clean and reinstall.
- Check valve (advanced): If water continues to drip when the unit is off, the internal check valve near the boiler may be leaking and require replacement.
