How to Fix / Troubleshooting

Safety first: Unplug the coffee maker and allow it to cool completely before opening any covers.

Run descaling cycle: Fill the tank with descaling solution and run at least one full descaling cycle to dissolve limescale in the flow meter and tubing.
Check water tank outlet: Ensure the valve at the bottom of the tank opens freely when pressed. Clean any debris.
Inspect hoses (advanced): If you are comfortable opening the unit, remove the top cover and check the silicone hoses for kinks or pinches. Straighten or reseat as needed.
Test with clear water: After descaling, run 2–3 full tanks of clean water to flush the system.
If error remains: The flow meter (small plastic wheel sensor in the water line) may be defective and should be replaced by a qualified technician.

Error 3 or three blinking LEDs; machine stops shortly after starting, little or no water dispensed.
