Water Circuit Empty / Fill Circuit means: The machine cannot detect water in the circuit; air is trapped or the pump is not priming.

Applies to: Magnifica, Dinamica and PrimaDonna.

Short answerAir has got into the pump, usually after the tank ran dry, after descaling, or after a new filter. The pump cannot push air, so pressure never builds and the machine asks you to fill the circuit.

How to fix Water Circuit Empty / Fill Circuit

  1. Fill the tank at least halfway, remove the water filter for now, and push the tank fully home.
  2. Fit the hot-water spout and press the hot water button; let it run until water flows steadily (may take two or three attempts).
  3. Refit the filter after priming it in water.
  4. If the pump buzzes but no water arrives after several attempts, descale; a scaled inlet or heater will not let it prime.
